What’s Shaking?

Three recent earthquakes were reminders to many Californians that we live in earthquake country! Yesterday, a 5.1 earthquake occurred near La Habra. 20 apartment units have been red-tagged in Fullerton. On March 9, a magnitude 6.8 earthquake occurred 50 miles offshore of Eureka (Northern California). Then on March 17th, a magnitude 4.4 earthquake occurred 2 miles south of Encino (Southern California), an early morning wake up call for millions of people. Even though it was a much smaller earthquake, its proximity meant that many people felt more intense (though shorter duration) shaking than in the 6.8 earthquake the week before.

These differences show how larger magnitude earthquakes do not always mean greater damage or injuries. To learn more, read the special report featuring the “ShakeMaps” for these two earthquakes, compared with two much more destructive earthquakes for which we will be commemorating anniversaries this year: the October 17, 1989, Loma Prieta earthquake and the January 17, 1994 Northridge earthquake.
