A new video from the Pacific Tsunami Warning Center maps every earthquake recorded in California in the last 30 years.  Check it out below.

The video starts in August 1989 and ends July 5, 2019 with the magnitude 7.1 quake in Ridgecrest.  The largest earthquake in the last 30 years was the magnitude 7.3 quake in the small Mojave Desert town of Landers in June 1992.

There is a composite image at the end of the video of all earthquakes, and really there are only a few areas in California that are earthquake free!
