Earthquake!

Today’s magnitude 7.9 earthquake was really interesting! It was centered far enough away from Anchorage (175 miles) to not do any damage, but boy did it rock the house for a long time! It also reminded me that it’s been a number of years since one of our local volcanoes has erupted. I’ve been here for eruptions of Redoubt and Spurr.

UPDATE
Peter Haeussler, of the U.S. Geological Survey, flew over the path of the Denali fault by helicopter to photograph the effects of Sunday’s earthquake. The fault line was visible for 140 miles, and his photos include a 16 foot offset near Augustana Creek, a long crack in Canwell Glacier, two rockslides over Black Rapids Glacier and many more. The Anchorage Daily News also has some photos of cracks in the highways of central Alaska, and the damage to the supports of the Trans-Alaska Pipeline. The pipeline, designed to withstand and 8.2 magnitude quake, successfully passed this test.
