Why is Alaska so susceptible to earthquakes and tsunamis?
Subduction zone earthquakes follow the descent of the Pacific plate down to 200 km or more. Alaska’s largest earthquakes, exceeding magnitude 8 and even 9, occur primarily in the shallow part of the subduction zone, where the crust of the Pacific Plate sticks and slips past the overlying crust.
What damage did the Great Alaska earthquake cause?
The four minute duration of shaking triggered many landslides and avalanches. Major structural damage occurred in many of the major cities in Alaska. The damage totalled 300-400 million dollars (1964 dollars). The number of deaths from the earthquake totalled 131; 115 in Alaska and 16 in Oregon and California.
