Remembering the Great Alaska Earthquake and Tsunami

The most powerful earthquake ever recorded in North America occurred 50 years ago, on March 27, 1964.

With a magnitude of 9.2, “The Great Alaska Earthquake” caused massive tsunamis that devastated the Alaska coastal communities of Valdez, Seward, Kodiak and Whittier, and caused widespread destruction along the U.S. and Canadian west coasts.

The tsunamis caused an estimated $1 billion in damage and killed 124 people in Alaska, California and Oregon. Tsunami waves reached as far away as Hawaii. Scientists even measured a wave height of 219 feet in Valdez Inlet.

The quake lasted approximately four minutes and powerful aftershocks continued for three weeks.
