On March 27, 1964, a 9.2-magnitude earthquake struck south-central Alaska. The quake fell on Good Friday (the Friday before Easter Sunday), and was named after the religious holiday.The Good Friday earthquake was a megathrust quake. Megathrust earthquakes occur in subduction zones, where one tectonic plate violently slides beneath another. Off the coast of Alaska, the Pacific plate jolted beneath the North American plate.The Alaskan coast was largely unprepared for the Good Friday earthquake. Houses, schools, and other buildings collapsed. Water and sewage pipelines were destroyed. Landslides wrecked electrical and gas lines. The quake resulted in several tsunamis, which caused damage as far away as California, Hawaii, and even Japan. More than 125 people died.
