On March 27, 1964 the Great Alaskan earthquake recorded struck in the middle of Prince William Sound at 5:36pm. Buildings fell and entire villages were submersed by the tsunami that followed. Considering the magnitude of the earthquake, Alaska seemed as if it was barely damaged at all. The residents and economy were still in tact for a number of reasons. On the contrary, the Alaskan economy prospered a little bit from the Great Alaskan earthquake by receiving additional federal funding. Military presence was declining, unemployment was growing, and it was all before the oil was discovered in Prudhoe Bay.
The Great Alaskan earthquake is also known as the Good Friday earthquake, because it happened on March 27, 1964, which happened to be on Good Friday. It is also the largest earthquake that has hit North America. The earthquake registered a magnitude of 8.6 on the Richter scale, although scientists now prefer a different magnitude scale. The new magnitude scaled is designed for very large earthquakes and now this earthquake as a 9.2.
The Geological effects were widespread and very dramatic. Several areas were lifted up or dropped by several feet, there were also landslides and ground failure, which led to large fissures. Several landslides into bays caused waves locally and a tsunami was felt in distant areas. Luckily, the casualties were minimal, than what would have been expected for a disaster of that magnitude. The earthquake itself, did not kill that many people. Such a sparse population in the areas affected can attribute the low number.
The earthquake was the result of the Pacific tectonic plate, being slid under the North American tectonic plate. When a plate doesn’t budge for a long time, it will cause a subduction earthquake, which causes the largest earthquakes. Volcanoes start to erupt as the descending Pacific Ocean plate is being sucked under the North American plate. The rock starts to melt and then magma rises to the surface. Irvine...
