On Monday, a 5.2 magnitude earthquake shook San Diego. The epicenter was located about 2 miles south of Julian.

It didn't cause major damage and no injuries were reported.

But, it was the biggest earthquake in our region since the 2010 earthquake near Guadalupe Victoria, which was a 7.2 magnitude earthquake.

On Midday Edition, we make sense of the earthquake with a seismologist. Plus, we hear some practical tips on how to prepare for the next quake, whether or not it's "The Big One."

Guests:

• Alice Gabriel, seismologist and associate professor at UCSD's Scripps Institution of Oceanography
