Alaska is Prone to Earthquakes

Alaska is faced with so many earthquakes that it has become kind of a common occurrence in that part. According to studies, every one to two years, Alaska or its offshore area is struck by an earthquake of magnitude 7 or more.

An earthquake of magnitude 8 or higher strikes Alaska every 13 years on average. The reason behind this amount of earthquakes being common in Alaska is the stress caused by the tectonic plates present on the planet’s outer shell.

In Alaska and its nearby regions specifically, the Pacific plates present underneath more northward at a steady rate of 2 inches per year and continue to descend or subduct beneath the North American plate.

Following are the steps you should take depending on the place you are in:

  • If indoors, then stay there and hide under a desk or table or stick to an inside wall.
  • If outside, then go into the open and stay away from buildings or similar structures.
