EERI’s Northern California Regional Chapter is hosting a FREE webinar on the recent M7 Alaska Hubbard Glacier Earthquake.
The M7 earthquake struck on December 6 at 11:41 AM local time. It occurred beneath the Hubbard Glacier in the St. Elias Mountains, a remote glaciated mountain region. The quake occurred at the northern tip of the Fairweather Fault System, part of the boundary between the Pacific and North American plates. It was characterized as a strike-slip event with a shallow depth of 3 miles. The epicentral area is sparsely populated having no reports of damage. However, over 700 landslides and snow avalanches across Alaska and Canada were triggered by the quake. The most intense failures occurred in a 10-mile-wide band along the rupture zone. Notably, some landslides had travel distances more than 3 miles.
Speakers:
-
Dr. Michael West is the Alaska State Seismologist and head of the Alaska Earthquake Center located in Fairbanks, Alaska. He will explain the seismology of the earthquake and how the Hubbard quake differs from other Alaska earthquakes from the recent past.
-
Dr. Kate Allstadt is a Research Geophysicist at the United States Geological Survey Geologic Hazards Science Center located in Golden, Colorado specializing in coseismic landslides. She will describe the mechanisms and significance of the numerous landslides and snow avalanches observed.
