There are people new to the area and more coming in that I just wanted to share this link for Ready San Diego.
You can sign up to get alerts and reversed 911 calls on your cell phone. Also the site gives tips on how to be ready for wild fires, earthquakes, tsunamis, etc. The disaster I have seen the most here is wildfires so it's really important to know what to do because they can get out of control in a heartbeat.
