On March 27, 1964, Good Friday, the strongest earthquake ever to be recorded in North America occurred between Anchorage and Valdez, Alaska.
The true strength of the earthquake, to this day, is still unknown. Different recordings of the magnitude of the earthquake were due to a variety of different equipment being used at that time.
Bruce Bolt recorded the earthquake’s magnitude to be 8.6 Ms. USGS recorded the magnitude to be 9.2 Mw (Moment Magnitude). The Epicenter of the earthquake itself was between Anchorage and Valdez, near Prince William Sound. The shaking of the earth triggered several rockslides and avalanches. Property damages skyrocketed to over $311,000,000.
The tectonic plate movement creating the earthquake caused the seafloor to rise, creating a strong Tsunami. The Tsunami traveled the Pacific Ocean at 400 miles per hour. It hit the Hawaiian Islands, California, and Oregon, killing over one hundred people.
The Earthquake was later followed by almost 60 aftershocks.
