a few years ago I was in San Diego and In the evening we heard the dogs and coyote's start howling in the canyon. Within 30 seconds we had a small quake. Its true I have been there and heard that !
Security cameras and recorders always have power back up. The cameras run on DC from a central point so power back up is easy. I used to instal them back in the day.
About 6 years ago Boogy, jumped up on my head , I thought what the heck at first, then I felt some thing wet and warm, I jumped up and said what the heck I got up and stuck my head in the shower half asleep and mad, and found out we had a 4.1 earth quake on the news that morning. Boogy was about 3 years old then, she is 5 years old in this picture and know she is going on 8 years old know
