Important Takeaways:
- Iceland Volcano Update: Eruption Map, Experts’ Views ‘Completely Changed’
- In an update on Tuesday, the Icelandic Meteorological Office said that the Reykjanes Peninsula—where an eruption was thought likely after a burst of seismic activity from November 10—would be subject to increased monitoring and more experts drafted in to help.
- On Wednesday, the Icelandic Met Office said the ground around Svartsengi “continues to inflate,” meaning “further dikes or an eruption remain possible.” While the area the previous dike formed is anticipated to be the most likely area of eruption, experts have not been able to discount the possibility that magma propagates elsewhere in the region.
- Between 1,500 and 1,800 earthquakes a day were being recorded from November 10 for nearly two weeks, before dropping to the low hundreds. Between 200-300 earthquakes have been registered a day in the past two days, while the Icelandic Met Office said as of 6:15 a.m. ET on Wednesday there had so far been a hundred.
- While the intense seismic activity around the vertical dike appears to have subsided for the time being, the continued flow of lava into the horizontal intrusion means another could form, or more magma flow into the dike, without warning.

Important Takeaways:
- Iceland Volcano Update: Eruption-Making Magma Shift May Be ‘Days’ Away
- Another upward shift of magma through the Earth’s crust under Iceland that has the potential to cause an eruption “could happen in the next few days or possibly after several months,” as officials have expressed “considerable” uncertainty as to when the next volcanic episode might occur.
- Last week, a decline in the number and severity of earthquakes around the magma intrusion led it to conclude that an eruption from the episode was less likely but still possible. However, experts have warned that volcanic activity in the region could pick up again.
- Between 1,500 and 1,800 earthquakes a day were being recorded from November 10 for nearly two weeks, before dropping to the low hundreds.
- The earthquakes have mostly occurred over and around the site of the magma dike—which is estimated to be around 9.3 miles long and runs alongside the coastal fishing town of Grindavik, on a southwesterly peninsula on Iceland’s main island.
- A sudden shift in the North American tectonic plate away from the Eurasian plate is thought to have allowed magma to suddenly push upwards through a rift that runs between the two of them under Iceland.
- One Icelandic volcanologist previously told Newsweek that while the volcanic episode may have ended, it may mark the start of an “intense” period of tectonic activity based on historic trends.
- “We know that this is not the end of activity on the Reykjanes peninsula”

Important Takeaways:
-
- The heightened seismic activity, which started more than a week ago within the Reykjanes Peninsula, continued into Saturday with approximately 1,700 earthquakes recorded in 24 hours, according to the Icelandic Meteorological Office.
- The office noted a high likelihood of volcanic eruption continues in the southwest along a 9-mile magma tunnel, with the highest likelihood of an eruption starting north of the small fishing town of Grindavík, which has a population of 3,400 and is located near Hagafell mountain
- Grindavík’s residents evacuated from the town last week before the chance to briefly re-enter on Thursday and Friday to collect important belongings, according to NBC…
- A volcanic eruption could disrupt air travel in other countries if it’s large enough. The 2010 eruption of Iceland’s Eyjafjallajökull volcano created massive plumes of ash that were swept into Europe by northerly winds, canceling more than 100,000 flights and creating $1.7 billion in lost revenue to airlines.

Important Takeaways:
- 23,000 Earthquakes in Just Weeks Raise Fears of Volcanic Eruption
- Iceland has recorded thousands of earthquakes, localized in the Reykjanes Peninsula, in recent days, with the Nordic country evacuating its famous Blue Lagoon geothermal spa amid fears of a possible volcanic eruption.
- The effects of the recent earthquakes were felt as far as Borgarnes town, 51 kilometers (~32 miles) away from the peninsula. The Icelandic Meteorological Office (IMO) has documented more than 23,000 tremors since October, including an earthquake of magnitude 5.0 on November 2nd, the largest spike in activity since tremors began.
- The Reykjanes Peninsula laid dormant for an estimated 800 years before an eruption in 2021. There are around 130 volcanoes across the island nation, most of which are active.

Important Takeaways:
- 400 earthquakes recorded under Mount St. Helens since mid-July
- Scientist says small quakes signal volcano is ‘recharging’
- About 400 earthquakes have rumbled under Mount St. Helens since mid-July, the largest chain of shakes since the volcano finished erupting in 2008, the U.S. Geological Survey reported last week.
- Small magnitude earthquakes, detected only by sensitive equipment, signal a volcano’s “recharging” as magma flows through chambers and cracks deep under the ground, said Wes Thelen, U.S. Geological Survey Cascades Volcano Observatory geophysicist and seismologist.
- Between late August and early September, scientists observed 40 to 50 earthquakes per week located between 2.5 to 5 miles below the crater floor, before recently dwindling to 30. To compare, Mount St. Helens averaged roughly 11 quakes per month since 2008.

Important Takeaways:
- Earthquakes Are a Special Kind of Nightmare
- There is something uniquely nightmarish about major earthquakes that strike under or close to villages, towns, and cities
- Tragedies born of geologic forces can be simultaneously extreme and swift. Volcanic eruptions can produce rivers of scorching gas, ash, and debris that move at breathtaking speed, igniting and scouring anything in their path. Tsunamis—caused by the dramatic twitching of tectonic plates and their faults, or by immense landslides, or by volcanic explosions—can, and have, effortlessly swept entire towns and villages aside in a matter of minutes.
- The essentially immediate, invisible arrival of an earthquake is almost supernatural. Science tells us that earthquakes arise from the sudden release of energy accumulated over years, decades, or centuries.
- A tsunami voyaging quickly across the ocean will set off alarms in distant countries, giving those who receive the warning some time to flee or brace themselves.
- Volcanoes usually give off warning signs hours, days, sometimes even months or years in advance that an eruption is likely on its way.
- But we currently do not have any way to know when the next significant earthquake will strike, precisely where it will strike, how powerful it will be, how much shaking it will cause, or what kind of damage it will do.

Important Takeaways:
- PHIVOLCS: Mayon volcanic earthquakes up, lava flows ‘bulked up’
- Slow effusion of lava from Mayon Volcano’s crater continued to feed and bulk up established lava flows amid an increase in volcanic earthquakes, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said Wednesday.
- “Respectively, these lava flows have maintained distal lengths of approximately 2.8 kilometers, 2.4 kilometers and 600 meters from the crater,” it said.
- PHIVOLCS also recorded 304 volcanic earthquakes and 137 rockfall events over the past 24 hours. The number of volcanic earthquakes was higher compared to the 267 recorded the previous day.
- Three pyroclastic density currents (PDCs) and 30 ashing events that lasted 20 to 40 seconds were also recorded.
- “The combined seismic energy release of these, however, has not increased beyond the trend of effusive activity,” PHIVOLCS said.
- “Alert Level 3 is maintained over Mayon Volcano, which means that it is currently in a relatively high level of unrest as magma is at the crater and hazardous eruption within weeks or even days is possible,” PHIVOLCS said.

Important Takeaways:
- Virginia Quakes May be ‘Foreshock’ for Something Bigger
- A series of six small earthquakes in Virginia since mid-June has left scientists concerned a larger event may be inbound, with Virginia Tech geophysics professor Martin Chapman warning: “When you see a series of these things in a smaller area, you have to take into account the fact that they may be foreshocks of a bigger earthquake.”
- The “burst of activity”, as Chapman put it, is unusual in the Old Dominion, with Virginians typically feeling only two or three earthquakes per year.
- “We [need to] take a close look at it and… monitor our instruments a little bit closer to make sure that we’re not missing any more little earthquakes, because if you see a continuous sequence that’s something that you have to pay attention to,” the professor explained.
- Virginia suffered its most powerful earthquake since the 19th century in 2011. The 5.8 magnitude quake inflicted up to $300 million in cost on the state and nearby Washington D.C., with homes and schools demolished, a nuclear power plant forced to shut down, and the Washington Monument and National Cathedral suffering serious structural damage.
- The 2011 quake was not predictable, however, with no “foreshocks” observed before it hit.
