Last night’s earthquake in East Bay
We were awakened by the sudden shake of entire house structure last night. Earthquake! Rushed to kid rooms and David and Emily were still in deep sleep. Waited for a while, and it seemed to be over. Just as we went back to sleep, a second wave of shake rattled the window and door.
I stayed up for a while and checked on earthquake.usgs.gov. The earthquakes were in the mountain area between Moraga and Danville, about 8km from our house in Walnut Creek. The first is 3.0, followed by the second one at 3.5. Both a quite shallow at 7.7km depth. That is why we can felt them so strongly.
We need to be more alert as the images of earthquake in China are fresh, and should put earthquake prep kit in a place that we can dash for cover.
