I've said it before, but that area near San Ramon has been way too seismically active for months and months now. And expert geologists/seismologists say the nearby #HaywardFault is long overdue for a Big One.

For the M4 earthquake on the Hayward fault near the Claremont this past September (9/22), which happened at 3 AM, both me & my wife we’re awakened by the P wave, so we both experienced the S wave when it hit!

Swamp of earthquakes in Hayward today. Our fault is letting out some energy. Hopefully they will stay in the 3 range. 😳 #haywardfault #CAearthquakes

We just had to #evacuate the #HUSD sites because of the second #Jolt of an #earthquake centered right near my house on the #HaywardFault in East #CastroValley. It was pouring rain and I was not dressed for being out in the rain for longer than dashing from car to building today.
