“Dynamic glaciers identified as cause of Southeast Alaska’s summer ‘ice quakes’”

Article by Matt Miller. Listen to the audio of a large iceberg in Antarctica scraping against the ocean floor or another iceberg and read the full article here.

Excerpt from the article:

“This year the ice quakes started in May, with a big spike in activity starting four days before late June’s heatwave in Southeast Alaska. Ruppert said there have already been a hundred ice quakes recorded so far in 2021.”

“Last year, glaciologist Jason Amundson of the University of Alaska Southeast actually flew out to investigate one of the bigger ice quakes near Wright Glacier and Mount Ogden on the United States-Canada border.

“The glaciers in that area are pretty small,” Amundson said. “To produce an earthquake like that, that could be detected regionally, you would need to have a pretty big event.””
