[17] The Government Hill school suffered from the Government Hill landslide, leaving it in two jagged, broken pieces. But the damage caused by any single event depends on the quake's depth, proximity to populated areas, building standards in the region, as well as the type of earthquake. Soil liquefaction, fissures, landslides, and other ground failures caused major structural damage in several communities and much damage to property. Studies of ground motion have led to a peak ground acceleration estimate of 0.140.18 g.[7], The Alaska earthquake was a subduction zone (megathrust) earthquake, caused by an oceanic plate sinking under a continental plate. However, due to the remote location of the epicenter and the low population density in the affected areas, the number of casualties was limited. Bulletin of the Seismological Society of America (1996) 86 (5): 12291237. Most coastal towns in the Prince William Sound, Kenai Peninsula, and Kodiak Island areas, especially the major ports of Seward, Whittier and Kodiak were heavily damaged by a combination of seismic activity, subsidence, post-quake tsunamis and/or earthquake-caused fires. [4] The pattern of energy release suggest the presence of three asperities along the plate interface, each causing a pulse of moment release.
