AI Thread Summary
Recent advancements in technology utilizing computer modeling on satellite imagery have revealed that a dormant volcano in the United States, located approximately 6 miles from a depth of 12 miles, is experiencing significant magma rise. This activity has led to notable surface deformation, marking the fastest rate of volcanic deformation recorded in Alaska. The research indicates that while volcanic deformation is not uncommon, the reactivation of dormant systems like Edgecumbe is rare. Edgecumbe is classified as a stratovolcano, which is characterized by explosive eruptions involving magma and potential pyroclastic flows. Its geographical proximity includes being 1200 miles from Vancouver, 600 miles from Anchorage, and just 2.5 miles from the nearest coast.

The discovery came from new technology the facilities employed that uses computer modeling on satellite imagery. The data showed that magma is rising in a United States volcano that’s been long dormant about 6 miles from a depth of about 12 miles.

It has caused significant surface deformation, according to researchers.

“That’s the fastest rate of volcanic deformation that we currently have in Alaska,” said the research paper’s lead author, Ronni Grapenthin, a University of Alaska Fairbanks associate professor of geodesy.

It's also unusual.
“And while it is not uncommon for volcanoes to deform, the activity at Edgecumbe is unusual because reactivation of dormant volcanic systems is rarely observed,” he added.

A little, but crucial note:

It is a stratovolcano, i.e. explodes with magma and possibly pyroclastic flows.
(in contrast to shield volcanos like Mauna Loa, or lava domes like Mount St. Helens)

1200 mi to Vancouver
600 mi to Anchorage
2.5 mi to the nearest coast
 
On August 10, 2025, there was a massive landslide on the eastern side of Tracy Arm fjord. Although some sources mention 1000 ft tsunami, that height represents the run-up on the sides of the fjord. Technically it was a seiche.

Hello, I’m currently writing a series of essays on Pangaea, continental drift, and Earth’s geological cycles. While working on my research, I’ve come across some inconsistencies in the existing theories — for example, why the main pressure seems to have been concentrated in the northern polar regions. So I’m curious: is there any data or evidence suggesting that an external cosmic body (an asteroid, comet, or another massive object) could have influenced Earth’s geology in the distant...
