PAHALA, Hawaii (Reuters) – The restive Kilauea Volcano belched clouds of ash into the skies over Hawaii’s Big Island twice more on Wednesday as civil defense authorities reported that pressurized geothermal wells at a nearby power plant had been spared from approaching lava.

The latest back-to-back upheavals of ash from the main summit crater of Kilauea — one before dawn and another several hours later — came on the 21st day of what geologists rank as one of the biggest eruption cycles in a century from one of the world’s most active volcanoes.

The earlier ash plume rose to a height of 8,000 feet (2,438 meters), while the later one reached about 5,000 feet (1,524 meters), authorities said.

Intermittent explosions of ash from the summit, believed to be driven by underground bursts of steam deep inside the throat of the crater vent, are occurring about twice a day, with smaller blasts in between, U.S. Geological Survey (USGS) vulcanologist Wendy Stovall told reporters.

The Hawaii County Civil Defense agency warned in its latest bulletin that residents downwind of Kilauea should take care to avoid exposure to ash, which can cause eye irritation and breathing difficulties, particularly in people with respiratory problems.

“The ash has just been nonstop every day since the summit has been erupting,” said Tiahti Fernandez, 24, as she sat in a car parked outside her father-in-law’s home in the tiny farming village of Pahala, 26 miles (42 km) southwest of the summit crater.

“Every day we have to wash our cars and wash down the patio because the ash just covers everything,” she said over the crowing of four roosters tethered to a chicken coop in the yard. “The air quality has been so bad that everybody has been walking around with a (dust) mask.”

A fine layer of brownish-gray ash coated vehicles and other surfaces, and an ash plume rising from the volcano summit was visible in the distance through the hazy air.

Emissions of sulfur dioxide gas, harmful if inhaled, also remained at high levels from newly opened lava-spewing fissures in the ground running through populated areas on the eastern flank of the volcano, authorities said.

“Residents in the affected area should be prepared to take leave of the area with little notice due to gas or lava inundation,” the civil defense bulletin warned.

CRISIS AVERTED AT GEOTHERMAL PLANT

One potential hazard that appeared to have been brought under control was at the Puna Geothermal Venture (PGV) plant, which provides about a quarter of the Big Island’s electricity.

Lava from an active fissure nearby had flowed onto the property early this week, posing the risk of toxic gases being released in the event molten rock encroached into any of several pressurized deep-underground wells.

Utility crews racing to quench the wells with cold water and plug them with mud had managed to mostly secure the site. The civil defense agency reported on Wednesday, “there is no immediate threat to any of the wells at PGV.”

The facility also received a respite from Mother Nature. Accumulations of cooled, hardened lava created a thick, 30-foot (9.14-meter) high wall of solid volcanic rock channeling fresh lava streams from fissures to the south, away from the PGV plant, USGS scientists said.

Authorities also were monitoring hazards from noxious clouds of acid fumes, steam and fine glass-like particles — called laze — emitted when lava flows pour into the ocean on the island’s southern end.

Laze — a term combining the words “lava” and “haze” — is formed when molten lava, reaching temperatures of 2,000 degrees Fahrenheit (1,093 Celsius), reacts with sea water. Although potentially fatal if inhaled, Stovall said the danger was confined to the immediate vicinity of laze plumes themselves.

Kilauea rumbled back to life on May 3 as it began extruding lava and sulfur dioxide emissions through a series of fissures, marking the latest phase of an eruption cycle that has continued nearly nonstop for 35 years.

The occurrence of new lava vents, now numbering about two dozen, have been accompanied by earthquakes and periodic eruptions from the summit crater.

At least 44 homes and other structures have been destroyed, and a man was seriously injured on Saturday when a chunk of lava shot out of a fissure and struck him in the leg.

Some 2,000 people remain under evacuation orders due to lava flows and sulfur dioxide gas. Civil defense officials said contingency plans for further evacuations were being prepared with National Guard officials in case they become necessary.

HONOLULU (Reuters) – Lava from Hawaii’s erupting Kilauea volcano is exploding as it pours into the ocean, shooting rock fragments that are a danger to boaters. Inland, where molten rock is burning through jungle, methane explosions are hurling boulders while toxic gas is reaching some of the highest levels seen in recent times.

These were new risks geologists warned of on Tuesday as Kilauea’s 19-day eruption showed no sign of easing, with repeated explosions at its summit and fountains of lava up to 160 feet (50 m) from giant cracks or fissures on its flank.

Lava edged towards a geothermal power plant on Tuesday after destroying an old warehouse near the facility, County of Hawaii Civil Defense said.

Workers at the closed Puna Geothermal Venture, which provided around 25 percent of electricity on Hawaii’s Big Island, worked to cap the last of three pressurized wells to reduce the risk of an uncontrolled release of toxic gases should they be inundated by lava.

The race at the site marked the latest challenge facing authorities during what geologists call an unprecedented, simultaneous eruption at Kilauea’s summit and from giant fissures 25 miles (40 km) down its eastern side.

“Fissures near Puna Geothermal Venture are active and producing lava slowly flowing onto the property,” Civil Defense said in a statement. “This activity has destroyed the former Hawaii Geothermal Project site,” it said referring to the warehouse.

An explosive eruption at the Kilauea summit at 3:45 a.m. (9:45 a.m. EST) sent ash to a height of 8,000 feet (2,438 meters) over Hawaii’s Big Island, civil defense said. Communities southwest of the summit were dusted with ash, said National Weather Service meteorologist John Bravender.

On the volcano’s east flank, nearly two-dozen fissures are producing 15,000 tons a day of toxic sulfur dioxide, a level “much higher than seen in recent times,” Bravender said.

MORE VIOLENT PHASE

The Puna district’s geothermal plant has been closed since shortly after lava began erupting on May 3 through newly opened fissures in the ground running through neighborhoods and roads in an area near the community of Pahoa.

About 3 miles (4.8 km) to the east of the plant on the coast, noxious clouds of acid fumes, steam and fine glass-like particles billowed into the sky as lava poured into the ocean from two lava flows.

At least 47 homes and other structures have been destroyed by nearly two dozen fissures in the Leilani Estates and Lanipuna Gardens, and a man was seriously injured on Saturday by flying lava. Around two thousand people have been forced to evacuate, and many others have voluntarily left their homes.

Lava creeps onto geothermal plant site on Hawaii’s Big Island

PAHOA, Hawaii (Reuters) – Molten lava from the erupting Kilauea Volcano on Hawaii’s Big Island crept onto a geothermal power plant site on Monday, as workers rushed to shut down the facility to prevent the uncontrollable release of toxic gases.

Crews worked into the night to cap the 11th and final well at the Puna Geothermal Venture (PGV) plant, which provides about 25 percent of the Big Island’s power, as lava from an active fissure flowed 200 to 300 yards from the nearest well pad, county and federal officials said.

“County, state, and federal partners have been collaborating closely to monitor the situation and work with PGV to ensure the safety of the surrounding communities,” the county said.

The race at the site marked the latest challenge facing authorities as they cope with what geologists rank as one of the biggest upheavals in a century from one of the world’s most active volcanoes.

The latest explosive eruption at the Kilauea summit occurred shortly before 6 p.m. local time, the Hawaiian Volcano Observatory reported.

“The resulting ash plume may affect surrounding areas,” it said.

The plant has been closed since shortly after lava began erupting on May 3 through newly opened fissures in the ground running through neighborhoods and roads on the far eastern flank of Kilauea.

Within a week, some 60,000 gallons (227,124 liters) of the highly flammable chemical pentane, which was stored at the plant, were moved from harm’s way. The state said last week it was pumping cold water into the wells and would cap them with iron plugs.

The plant’s wells run 6,000 to 8,000 feet (1,829-2,438 meters) underground to tap into extremely hot water and steam used to run turbines and produce electricity.

LAZE ALERT

About 3 miles (4.8 km) to the east of the plant on the coast, noxious clouds of acid fumes, steam and fine glass-like particles billowed into the sky as lava poured into the ocean from two flows cutting across Highway 137, one of the main exit routes from the eruption zone.

Laze — a term combining the words “lava” and “haze” — is formed when erupting lava, which can reach 2,000 degrees Fahrenheit (1,093 degrees Celsius), reacts with sea water. It is potentially deadly if inhaled.

“If one were to be near the laze, because of the various acids, it would be corrosive to the eyes, the nose and respiratory tract, and the skin,” Dr. Alvin Bronstein from the Hawaii State Department of Health told journalists on a conference call.

Laze killed two people when a lava flow reached the coast in 2000, and authorities warned residents to stay clear of it.

Another hazard was the potential for methane gas explosions as searing lava neared pockets of rotting vegetation, igniting traces of the flammable gas given off by the decay.

“These are quite a big hazard in vegetative areas and the explosions can occur well away from the lava flow itself,” USGS geologist Janet Babb said on the call.

Geologists say Kilauea’s eruption, which has already produced around two dozen lava-spewing fissures, has now entered a more violent phase, in which larger volumes of molten rock are oozing from the ground and traveling farther than before.

At least 44 homes and other structures have been destroyed in the Leilani Estates and Lanipuna Gardens area of the Puna district, and a man was seriously injured on Saturday when a plate-sized chunk of molten shot out of a fissure and struck him on the leg.

Two thousand people have been ordered from their homes due to lava flows and toxic sulfur dioxide gas, levels of which have tripled in the last two days, according to civil defense officials. The Hawaii National Guard has warned of more mandatory evacuations if further highways are blocked.

Deadly acid cloud rises over Hawaii as lava streams into ocean

PAHOA, Hawaii (Reuters) – Deadly white clouds of acid and fine shards of glass boiled into the sky over Hawaii on Monday as lava from the Kilauea volcano flowed into the ocean, creating a new hazard from a more than two-week eruption.

Hawaii’s Civil Defense agency warned motorists, boaters and beachgoers to beware of toxic clouds of so-called “laze” — a combination of “lava” and “haze” — which formed as two streams of hot lava poured into sea water.

The caustic plume, which can be fatal if inhaled, was the latest danger in an eruption that shows no signs of stopping, Since it started on May 3. It has already produced around two dozen lava-spewing cracks, the same number as a previous 88-day event in 1955.

The eruption has entered a more violent phase, in which large volumes of rich, orange molten rock, hotter and faster than older magma, are streaming out of fissures in the ground that have erupted around a small area of rural communities.

“We’ve seen Phase 1. We’ve seen the clearing out of the system. We call that the ‘throat-clearing’ phase,” Carolyn Pearcheta, operational geologist at the Hawaiian Volcano Observatory, told reporters on a conference call.

Lava has destroyed at least 44 homes and other structures in the Leilani Estates and Laipuna Gardens area of the Puna district.

A “lava bomb”, a plate-sized chunk of lava that flew horizontally out of a fissure, seriously injured one man on Saturday.

Two thousand people have been ordered from their homes due to lava flows and toxic sulfur dioxide gas, levels of which have tripled in the last two days, according to the County of Hawaii Civil Defense. Hawaii National Guard has warned of more mandatory evacuations if further highways are blocked.

Flows of molten rock are traveling at around 400 yards (meters) per hour, twice as fast as earlier streams, Pearcheta said. Lava is expected to begin sending fountains of lava up to 600 feet (183 meters) into the air, three times as high as before, she added.

The new laze threat, which killed two people when a lava flow reached the coast in 2000, is a mix of hydrochloric acid fumes, steam and fine volcanic glass specks created when erupting lava, which can reach 2,000 degrees Fahrenheit (1,093 degrees Celsius), reacts with sea water.

The cloud could extend as far as 15 miles (24 km), mostly along the coast and offshore, geologists said on Sunday. Even a wisp can cause eye and respiratory irritation, and it causes acid rain that has corrosive properties equivalent to diluted battery acid, the U.S. Geological Survey said.

An air quality index for Kona, about 40 miles (64 km) northwest of the eruption site, was at “orange,” meaning older individuals and those with lung problems could be affected.

Hawaii faces new threat of fumes from volcano’s lava

PAHOA, Hawaii (Reuters) – Hawaii faced a new hazard on Sunday as lava flows from Kilauea’s volcanic eruption could produce clouds of acid fumes, steam and glass-like particles as they reach the Pacific, authorities said.

Civil defense notices cautioned motorists, boaters and beachgoers to beware of caustic plumes of “laze” formed from two streams of hot lava pouring into the sea after cutting across Highway 137 on the south coast of Hawaii’s Big Island late on Saturday and early Sunday.

The bulletins also warned that reports of toxic sulfur dioxide gas being vented from various points around the volcano had tripled, urging residents to “take action necessary to limit further exposure.”

Laze – a term combining the words “lava” and haze” – is a mix of hydrochloric acid fumes, steam and fine volcanic glass specks created when erupting lava, which can reach 2,000 degrees Fahrenheit (1,093 degrees Celsius), reacts with sea water, Hawaii County Civil Defense said in a statement.

“Be aware of the laze hazard and stay away from any ocean plume,” the agency said, warning that potential hazards include lung damage, as well as eye and skin irritation.

Under Sunday’s conditions, with strong winds and copious amounts of lava hitting the ocean, the laze plumes could extend as far as 15 miles (24 km), mostly along the coast and offshore, though the hazard would diminish the farther out to sea it blows, according to USGS geologist Janet Babb.

Authorities cautioned, however, that wind patterns can change abruptly. The U.S. Coast Guard was “actively monitoring” the area to keep away all vessel traffic except permitted tour boats, the civil defense office said.

Laze killed two people when a lava flow reached the coast in 2000, and even a wisp can cause eye and respiratory irritation, the U.S. Geological Survey said. Acid rain from laze has corrosive properties equivalent to diluted battery acid, the agency said.

The section of coastal Highway 137 and a nearby a state park in the area where lava was pouring into the ocean were both closed, and another road in the vicinity was restricted to local traffic as a precaution due to elevated levels of sulfur dioxide gas.

An air quality index for Kona, about 40 miles (64 km) northwest of the eruption site, was at “orange” level, meaning that older individuals and those with lung problems could be affected.

EARTHQUAKES, ASH ERUPTIONS

Kilauea, one of the world’s most active volcanoes, began extruding red-hot lava and sulfuric acid fumes through newly opened fissures on the ground along its eastern flank on May 3, marking the latest phase of an eruption cycle that has continued nearly nonstop for 35 years.

The occurrence of new lava-spewing vents, now numbering at least 22, have been accompanied by flurries of earthquakes and periodic eruptions of ash, volcanic rock and toxic gases from the volcano’s summit crater.

The lava flows have destroyed dozens of homes and other buildings, ignited brush fires and displaced thousands of residents who were either ordered evacuated or fled voluntarily.

The volcano has also fed a phenomenon called vog, a hazy mix of sulfur dioxide, aerosols, moisture and dust, with fine particles that can travel deep into lungs, the USGS said.

On Saturday, authorities reported the first known serious injury from the eruptions – a homeowner whose leg was shattered by a hot, solid lumb of lava called a “lava bomb” while standing on the third-floor balcony of his home.

Mark Clawson, a friend of the victim who did not want his name used, lives near where his friend was staying as caretaker, and heard screaming and saw the harrowing aftermath, he told Reuters.

Apparently a fiery 5-pound “lava bomb” about the size of a dinner plate was launched from a fissure about 200 yards from the house, Clawson said.

“Most of them (lava bombs) arc high in the air, but every now and again there’s one that gets shot like a rifle, more horizontal and that’s what happened here,” he said.

It also started a small fire, which Clawson helped douse.

He said doctors had to pick sharp, hardened fragments of lava out of the wound, but the prognosis is good for his friend.

With Highway 137 severed, authorities were trying on Sunday to open up nearby Highway 11, which was blocked by almost a mile of lava in 2014, to serve as an alternate escape route.

The Hawaii National Guard has warned of additional mandatory evacuations if more roads become blocked.

Officials at the Hawaii Volcano Authority have said hotter and more viscous lava could be on the way, with fountains spurting as high as 600 feet (182 meters), as seen in a 1955 eruption.

Hawaii volcano spews 6 mile-high plume of ash, could blow again

PAHOA, Hawaii (Reuters) – Hawaii’s Kilauea volcano spewed ash nearly six miles (9 km) into the sky on Thursday and scientists warned this could be the first in a string of more violent explosive eruptions with the next possibly occurring within hours.

“This has relieved pressure temporarily,” U.S. Geological Survey geologist Michelle Coombs told a news conference in Hilo. “We may have additional larger, powerful events.”

Residents of the Big Island were warned to take shelter from the ash as toxic gas levels spiked in a small southeast area where lava has burst from the ground during the two-week eruption.

The wind could carry Kilauea’s ash plume as far as Hilo, the Big Island’s largest city and a major tourism center, the County of Hawaii Civil Defense warned in an alert.

“Protect yourself from ash fallout,” it said.

Some Big Island residents had feared “the big one” after Kilauea shot anvil-sized “ballistic blocks” into the visitors’ car park on Wednesday and was rocked by earthquakes that damaged buildings and cracked roads in the park that was closed last week.

But geologists said the 4:15 a.m. (10:15 a.m. EDT) explosion was not particularly large and on a par with the last series of steam-driven blasts, which took place in 1924.

“The activity is such that they can occur at any time, separated by a number of hours,” Hawaiian National Volcano Observatory Deputy Scientist-In-Charge Steve Brantley told reporters on a conference call.

Geologists said it was extremely unlikely Kilauea would have a massive eruption like that of 1790 which killed dozens of people in the deadliest eruption to occur in what is now the United States.

Kilauea’s falling lava lake has likely descended to a level at or below the water table, allowing water to run on to the top of its lava column and create steam-driven blasts, they said.

“I don’t think there is a big one that’s coming,” said University of Hawaii vulcanologist Scott Rowland.

“I think it’s going to be a series of explosions similar to the one that happened this morning, and that’s based on what happened in 1924, which is really our only analog,” he said of the nearly century old event, which lasted 2-1/2 weeks and killed one person who was hit by a “ballistic block.”

On Thursday, a 21st fissure also opened in Leilani Estates while other fissures reactivated with lava, the Hawaii Civil Defense said in an alert.

ASH MASKS

A spike in toxic sulfur dioxide gas levels closed schools around the town of Pahoa, 25 miles (40 km) east of the volcano, where lava from giant cracks has destroyed 37 homes and other structures and forced about 2,000 residents to evacuate.

A change in wind direction caused gas spewing from fissures to drift northwest towards Pahoa, prompting National guard troops to don gas masks at a nearby road intersection, according to a Reuters reporter.

Pahoa fire station recorded a “red level” of sulfur dioxide, meaning the gas would cause choking and an inability to breathe, Fenix Grange of the Hawaii Department of Health told a news conference in Hilo.

“If it’s red, it’s get out of Dodge,” she said.

There have been no deaths or serious injuries reported during the current eruption.

Civil defense workers handed out one ash mask per family member in communities close to Kilauea to protect residents from the powdered rock, which is not poisonous but causes irritation to eyes and airways.

Volunteers handed out some 5,000 dust masks in less than three hours in the community of Kea’au, north of Pahoa at one of the four distribution points that were opened on Thursday.

“It was just thick, eyes watering kinda stuff,” said Glenn Severance, 65, a resident of Hawaii Paradise Park.

“I just wanted to have something,” said Severance, adding he knew the mask would not protect against toxic volcanic gases.

An aviation red alert was in effect due to risks ash could be carried into aircraft routes and damage jet engines, USGS said. Passenger jets generally cruise at around 30,000 feet, the height of Thursday’s plume.

Across the Big Island, home to 200,000 residents, people were encouraged to take caution driving, as ashfall can make roads slippery, and not go outdoors unless necessary.

But by 1:30 p.m. (7:30 p.m. EDT) reported ashfall was limited to only light, wet deposits about 3-4 miles (5-6 km) northwest of the summit, as rain over the volcano curbed the spread of ash.

Thursday’s eruption lasted only a few minutes, said Coombs who called it “a big event that got people’s attention, but did not have widespread impact”.

“Tall but small,” she said of Thursday’s plume.

‘Ash fallout’ alert after Hawaii volcano erupts in 30,000-foot plume

PAHOA, Hawaii (Reuters) – An explosive eruption spewed ash 30,000 feet (9,144 meters) into the air above Hawaii’s Kilauea volcano on Thursday and residents of the Big Island were warned to take shelter as the plume engulfed a wide area, authorities said.

The wind could carry the ash plume as far as Hilo, the Big Island’s largest city and major tourism center, the County of Hawaii Civil Defense warned in an alert.

“Protect yourself from ash fallout,” it said.

The 4:15 a.m. (10:15 a.m. ET) blast that sent ash and smoke nearly six miles into the atmosphere was followed by other emissions of up to 12,000 feet, the U.S. Geological Survey said in a statement.

USGS geologists and staff were evacuated from the summit shortly before the blast and a webcam showed a gray plume of ash and chunks of magma known as pyroclasts that showered the volcano’s slopes.

An aviation red alert was issued due to risks that ash could be carried into aircraft routes and damage jet engines, USGS said.

The eruption could not only enshroud large areas of the Big Island in volcanic ash and smog but other Hawaiian Islands and potentially distant areas if the plume reaches up into the stratosphere and ash is carried by winds.

National Guard troops donned gas masks to protect themselves from toxic sulfur dioxide gas at the intersection of highways 130 and 132, the main exit routes from the village of Pahoa, 25 miles (40 km) east of the volcano, where many of the ground fissures have erupted, a Reuters reporter in the village said.

Schools were closed in the area due to “elevated sulfur dioxide (SO2) levels,” according to a phone alert from emergency authorities

The volcano has destroyed at least 37 homes and other structures in a small southeast area of the island where lava has oozed from fissures, forcing around 2,000 people to evacuate their homes.

Geologists had warned explosive eruptions could begin once Kilauea’s falling lava lake descended below the water table, allowing water to run on to the top of the lava column and create steam-driven blasts.

The powerful explosions could hurl “ballistic blocks” the size of refrigerators across a distance of more than half a mile (1 km) and shoot pebble-sized projectiles and debris up to a dozen miles, the USGS has warned.

Kilauea, one of the most active volcanoes in the world, last experienced explosive eruptions in 1924.

‘Ballistic blocks’ shoot from Hawaii volcano, may mark start of violent eruptions

VOLCANO, Hawaii (Reuters) – “Ballistic blocks” the size of microwave ovens shot from Hawaii’s Kilauea volcano on Wednesday in what may be the start of explosive eruptions that could spew huge ash plumes and hurl smaller rocks for miles (km), the U.S. Geological Survey said.

Such eruptions, last seen nearly a century ago, have been a looming threat since Kilauea, one of the world’s most active volcanoes, erupted nearly two weeks ago.

Explosions in Kilauea’s crater sparked an aviation red alert due to risks the ash plume could blow into aircraft routes and damage jet engines.

More explosions are expected and may be more powerful, the USGS warned. These steam-driven blasts could send a 20,000-foot (6,100-meter) ash plume out of the crater, hurling 10-12 ton boulders up to half a mile (800 meters) and scatter pebble-sized rocks over 12 miles (19 km), the USGS has said.

This type of eruption has the potential to carpet the Big Island in much thicker ash than current dustings and possibly spread the powder and volcanic smog across the Hawaiian islands and farther afield if it enters the stratosphere.

“This morning dense ballistic blocks up to 60 cm (2 feet) across were found in the parking lot a few hundred yards (meters) from Halemaumau (Kilauea’s crater),” the USGS said in a statement. “These reflect the most energetic explosions yet observed and could reflect the onset of steam-driven explosive activity.

A 4.2 magnitude earthquake at the volcano at 8.36 a.m. (2:36 p.m. EDT) prompted authorities to issue an alert reassuring rattled Big Island residents that there was no risk of a tsunami from the volcanic activity.

‘DISARRAY AND FRANTIC’

In the community of Volcano, just north of Kilauea’s crater, business was way down and people were on edge.

In just a few hours residents had been shaken by an earthquake, dusted with ash and for the first time since the start of the eruption smelled the rotten-egg stench of toxic sulfur-dioxide gas.

“They’re just in disarray and frantic,” Adele Tripp, an employee at the Kilauea General Store, said of other residents. She said she had lived in Volcano for 30 years and was not personally concerned as she trusted scientists to tell her when to get out.

Smog from Kilauea drifted north up the island chain as the districts of Kau, Puna, and North and South Hilo were told by the National Weather Service to expect ashfall. Hawaii County Civil Defense said a dusting of ash was visible on property and advised residents to avoid exposure to the powdered rock, which can cause irritation to eyes and airways.

There was no effect on air carrier operations to Hawaii on Wednesday, Federal Aviation Administration spokesman Ian Gregor said in an email.

Ash is a new hazard for Hawaii’s Big Island, already grappling with volcanic gas and lava that has destroyed 37 homes and other structures and forced the evacuation of about 2,000 residents from a small area in the southeast Puna district.

Lava has burst from 21 giant ground cracks or fissures and torn through housing developments and farmland, threatening two highways that are exit routes for coastal areas.

Several fissures shot lava into the air on Wednesday but one flow advanced only 100 yards (meters) toward coastal Highway 137, which remains around a mile (1.6 km) distant, County of Hawaii Civil Defense said in a statement.

No serious injuries or deaths have been reported from the eruption.

PAHOA, Hawaii (Reuters) – Explosions intensified on Hawaii’s Kilauea volcano on Tuesday, spewing ash and triggering a red alert for aircraft for the first time since the latest eruption began 12 days ago.

Ash and volcanic smog, or vog, as it is called, rose to 12,000 feet (3,657 meters) above Kilauea’s crater and floated southwest, showering cars on Highway 11 with gray dust and prompting an “unhealthy air” advisory in the community of Pahala, 18 miles (29 km) from the summit.

An aviation red alert means a volcanic eruption is under way that could spew ash along aircraft routes, the U.S. Geological Survey (USGS) says on its website.

Ash was also a new hazard for residents of Hawaii’s Big Island, already grappling with volcanic gas and lava that has destroyed 37 homes and other structures and forced the evacuation of about 2,000 residents.

A shift in winds was expected to bring ash and vog inland on Wednesday and make them more concentrated, said John Bravender of the National Oceanic and Atmospheric Administration (NOAA).

“We’re observing more or less continuous emission of ash now with intermittent, more energetic ash bursts or plumes,” Steve Brantley, a deputy scientist in charge at the Hawaiian Volcano Observatory (HVO), said on a conference call with reporters.

The observatory warned the eruption could become more violent.

“At any time, activity may become more explosive, increasing the intensity of ash production and producing ballistic projectiles near the vent,” the HVO said in a statement on the change in aviation alert level to red from orange.

Ash is not poisonous but irritates the nose, eyes and airways. It can make roads slippery and large emissions could cause the failure of electrical power lines, said USGS chemist David Damby.

 

 

NEW FISSURE

The eruption has hit the island’s tourism industry.

Big Island summer hotel bookings have dropped by almost half from last year, Rob Birch, executive director of the Island of Hawaii Visitor Bureau, told journalists on a conference call.

College exchange student Constantin Plinke, 24, was planning to go to the Hawaii Volcanoes National Park before it was shut.

“We had a big list of things to do and maybe 80 percent of them were in the national park,” he said, after stopping by the side of the road to watch ash plumes rising into the air. “It’s sad.”

The area taking the brunt of the eruption is about 25 miles (40 km) down Kilauea’s eastern flank, near the village of Pahoa. Lava has burst from the ground to tear through housing developments and farmland, threatening one of the last exit routes from coastal areas, state Highway 132.

The latest fissure in the earth opened on Tuesday, spewing lava and toxic gases that pushed air quality into “condition red” around Lanipuna Gardens and nearby farms, causing “choking and inability to breathe,” the Hawaiian Volcano Observatory and Hawaii County Civil Defense said.

Road crews put metal plates over steaming cracks on nearby Highway 130 and reopened it to give coastal residents an escape route should a lava flow reach the ocean and block another road, Highway 137, Civil Defense said.

No major injuries or deaths have been reported from the eruption.

A looming menace remains the possibility of an “explosive eruption” of Kilauea, an event last seen in 1924. Pent-up steam could drive a 20,000-foot (6,100-meter) ash plume out of the crater and scatter debris over 12 miles (19 km), the USGS said.

Lava threatens Hawaii exit routes, could spur more evacuations

PAHOA, Hawaii (Reuters) – Lava flowing from giant rips in the earth on the flank of Hawaii’s erupting Kilauea volcano threatened highways on Monday, raising the possibility officials may order thousands more people to evacuate before escape routes are cut off.

Lava from a huge new fissure tore through farmland towards a coastal dirt road that is one of the last exit routes for some 2,000 residents in the southeast area of Hawaii’s Big Island.

More lava-belching cracks are expected to open among homes and countryside some 25 miles (40 km) east of Kilauea’s smoking summit, possibly blocking one of the last exit routes, Highway 132.

Fountains of magma spouted “lava bombs” more than 100 feet (30 meters) into the air as the molten rock traveled east-southeast towards the coastal road – Highway 137 – the Hawaiian Volcano Observatory said.

Mass evacuations would be triggered if either highway is hit by lava, said Hawaii National Guard spokesman Jeff Hickman.

“There’s a lot of worst-case scenarios and roads getting blocked is one of them,” said Hickman, standing on Highway 137, in the potential path of the lava flow, some two miles (3 km) away.

ERUPTIONS COULD LAST WEEKS

Dozens of homes have been destroyed since eruptions began 10 days ago and officials have ordered the evacuations of nearly 2,000 residents in the lower Puna district of the Big Island, home to around 187,000 people.

The American Red Cross said 500 people sought refuge in its shelters on Sunday night because of worsening volcanic activity.

Two more fissures opened in the past 24 hours, bringing the total to 19.

“It’s optimistic to think that this is the last fissure we’re going to see,” said Hawaiian Volcano Observatory Deputy Scientist-In-Charge Steve Brantley. A similar seismic event in 1955 lasted 88 days, he said.

Unnerved by near-constant small earthquakes and emissions of toxic sulfur dioxide gas, Rob Guzman and his husband Bob Kirk left their home in Kalapana Seaview Estates while they still could.

“We just need the local government to calm down the panic that some of these 2,000 people are feeling, that today, we’re going to be trapped with no way out,” said Guzman, who left behind a banana farm and rental properties to go stay with friends.

The Hawaii Fire Department issued a “condition red” alert on Monday because fissures in the southeast area of the Lanipuna Gardens area were issuing high levels of sulfur dioxide.

“Condition RED means immediate danger to health so take action to limit further exposure. Severe conditions may exist such as choking and inability to breathe,” the department said in the alert.

While residents deal with noxious gas and lava on the ground, the U.S. Geological Survey is concerned that pent-up steam could cause a violent explosive eruption at the volcano crater, launching a 20,000-foot (6,100-meter) plume that could spread debris over 12 miles (19 km).

Scientists had expected such explosions by the middle of this month as Kilauea’s lava lake fell below the water table. The possibility exists, however, that water may not be entering the crater, as feared, and gas and steam may be safely venting, scientists said.

“So far those explosions have not occurred and I think the key here is that the vent system is an open one, therefore pressure is not being built or developed down at the top of the lava column,” Brantley told a conference call.
