This week Chile experienced an 8.3 earthquake.

Big Bear had a 4.0.
And we had a tsunami alert for the beaches in Los Angeles. We regularly get earthquakes in California and you can see the latest here:

In preparation for our annual Shakeout drill, we have the following earthquake special.
Many people don't understand the Richter scale, as the intensity from one magnitude to the next is not logarithmic, but exponential. Compare equivalent energy release from the Northridge (5.6) vs San Francisco (7.8).
USGS put together the Shakeout Scenario to demonstrate a feasible earthquake and the effects it might have. This video puts that study into an alarming reality.
The best advice is always to DROP, COVER & HOLD. L.A. County Fire Department explain why.
Be prepared, and get an earthquake app. It's free and useful.
