Japanese volcano spews plumes of ash, people warned away

TOKYO (Reuters) -A volcano erupted in Japan on Wednesday, blasting ash several miles into the sky and prompting officials to warn against the threat of lava flows and falling rocks, but there were no reports of injuries or casualties.

Mount Aso, a tourist destination on the main southern island of Kyushu, sent plumes of ash 3.5 km (2.2 miles) high when it erupted at about 11:43 a.m. (0243 GMT), the Japan Meteorological Agency said.

It raised the alert level for the volcano to 3 on a scale of 5, telling people not to approach, and warned of a risk of large falling rocks and pyroclastic flows within a radius of about 1 km (0.6 mile) around the mountain’s Nakadake crater.

Local police said there were no reports of people injured or missing as of Wednesday evening, and that 16 people who had gone hiking on the mountain earlier on the day came back safely.

Television networks broadcast images of a dark cloud of ash looming over the volcano that swiftly obscured large swathes of the mountain.

Ash falls from the 1,592-metre (5,222-foot) mountain in the prefecture of Kumamoto are expected to shower nearby towns until late afternoon, the weather agency added.

Mount Aso had a small eruption in 2019, while Japan’s worst volcanic disaster in nearly 90 years killed 63 people on Mount Ontake in September 2014.

UK lowers COVID-19 alert status as pressure on hospitals eases

LONDON (Reuters) – The chief medical officers of the United Kingdom lowered their COVID-19 alert level on Thursday, citing a gradual reduction in pressure on the health service.

“Following advice from the Joint Biosecurity Center and in the light of the most recent data, the four UK Chief Medical Officers and NHS England National Medical Director agree that the UK alert level should move from level 5 to level 4 in all four nations,” Britain’s health ministry said in a statement.

Public health services in England, Scotland, Wales and Northern Ireland operate separately in most cases.

“The health services across the four nations remain under significant pressure with a high number of patients in hospital, however thanks to the efforts of public we are now seeing numbers consistently declining,” the medical officers added.

Alert level raised for Hawaii volcano due to rumbles, quakes

(Reuters) – The Mauna Loa volcano in Hawaii has been hit by at least 50 small earthquakes since October of last year, scientists said on Tuesday, prompting U.S. geologists to raise its alert level to yellow.

An eruption of Mauna Loa, the world’s largest active volcano, did not appear to be imminent. The increased seismic activity indicated a shift in the “shallow magma storage system” under the mountain, the Hawaii Volcano Observatory (HVO) said in an advisory.

“As has happened before, it is possible that current low-level unrest will continue and vary in intensity for many months, or even years without an eruption,” the observatory said. “It is also possible that the current unrest is an early precursor to an eventual eruption. At this time, we cannot determine which of these possibilities is more likely.”

Yellow is the second level on the Hawaii Volcano Observatory’s color-coded alert chart, above green, which is used to indicate “background, non-eruptive state.” Orange signifies a volcano exhibiting “heightened or escalating unrest with increased potential of eruption.” The highest alert level, red, indicates that an eruption is imminent.

“HVO expects that days or weeks prior to an eruption, monitoring instruments will detect signs of an increased potential for eruption,” the observatory said. “However, it is also possible that the time frame to eruption could be shorter – hours to days. All communities on the flanks of the volcano should be prepared.”

The last episode of volcanic activity in Hawaii was a destructive eruption of lava last summer from a series of fissures that opened at the foot of Kilauea Volcano, also on the Big Island.

Kilauea spewed rivers of molten rock that swallowed hundreds of homes before creeping several miles (km) to the ocean, ultimately engulfing two seaside housing developments there.

The property losses from the May-to-August event marked the most destructive eruption event of Kilauea or any other volcano in Hawaii’s recorded history.

Mauna Loa, which takes up more than half of the Big Island, and rises 13,679 feet (4,169 meters) above the Pacific Ocean, last erupted in March and April of 1984, sending a flow of lava within 5 miles (8.05 km) of the city of Hilo.

The volcano has produced voluminous flows of lava that have reached the ocean at least eight times since 1868, and twice its eruptions have destroyed villages, in 1926 and 1950.
