I finally found the location on the USGS site that has realtime maps of earthquake activity, so I was able to verify the shaking that I felt. It still hasn’t shown up on the list of quakes, but at least the map there told me there was a big quake in central California. And other people in San Francisco said they felt it too. Ah, an update from the USGS site. It’s really really official now. I feel validated.
