The Alaska earthquake was a
subduction zone (megathrust) earthquake, caused by an oceanic plate sinking under a continental plate. The fault responsible was the
Aleutian Megathrust, a reverse fault caused by a compressional force. This caused much of the uneven ground which is the result of ground shifted to the opposite elevation.
Tsunamis
![Calculated Travel Time Map for 1964 Alaska Tsunami](https://upload.wikimedia.org/wikipedia/commons/6/62/Calculated_Travel_Time_Map_for_1964_Alaska_Tsunami.jpg)
Two types of tsunami were produced by this subduction zone earthquake. There was a tectonic tsunami produced in addition to about 20 smaller and local tsunamis. These smaller tsunamis were produced by submarine and subaerial landslides and were responsible for the majority of the tsunami damage. Tsunami waves were noted in over 20 countries, including Peru, New Zealand, Papua New Guinea, Japan, Mexico, and in the
continent of Antarctica. The largest tsunami wave was recorded in
Shoup Bay, Alaska, with a height of about .

Nine more struck over the next three weeks. In all, thousands of aftershocks occurred in the months following the quake, and smaller aftershocks continued to strike the region for more than a year.
Recovery efforts
Alaska had never experienced a major disaster in a highly populated area before, and had very limited resources for dealing with the effects of such an event. In Anchorage, at the urging of geologist
Lidia Selkregg, the City of Anchorage and the Alaska State Housing Authority appointed a team of 40 scientists, including geologists, soil scientists, and engineers, to assess the damage done by the earthquake to the city.
