Just got a text from my daughter in Los Angeles (Miracle Mile area). She was out running errands while she could. It's been raining and windy. She figured she better finish up errands early today. She parked in a newer underground parking garage by the store and her car started rocking back and forth from an earthquake. She said it lasted about 30 seconds.
I looked up USGS and Ojai, California was hit with a 5.1 and since then they've had 5 more of 3.1 - 3.6 magnitude.
So....0.005 psi? If it all fell in unison, whoch it doesnt.
Using bizarre measurement bases to make things sound big is ridiculous.
