as they relieve stress up and down the fault line. If the stress is relieved, then it builds until a much bigger quake happens.

Common Myths and Misconceptions
Can small EQ's relieve stress to prevent large ones?
If you look at earthquake statistics in most regions of the world, including California, you will find that for every magnitude 5 earthquake, there are about 10 that have a magnitude of 4, and for each magnitude 4, there are 10 with magnitude 3. Unfortunately, this means there are not enough small earthquakes to relieve enough stress to prevent the large events. In fact, it would take 32 magnitude 5's, 1000 magnitude 4's, or 32,000 magnitude 3's to equal the energy produced in one magnitude 6 event.

Another common myth is "earthquake weather"

I'm in San Diego County. I was in a zoom meeting, when all of a sudden things started shaking in the house.

Having lived in California all my life, it's another one of those, 'is it going to get bigger or is it going to go away?' moments. Do I need to leave the zoom meeting, or can I stay?
