Jolted out of sleep by a late nigth earthquake...right underneath my house.

Depending on where you live, it lasted between 4 and 30 seconds.

If you zoom in, you can see that the shaking frequency was about 3-4 Hz.

This is how people around the Bay Area reportely felt it.

The automated system will immediately detect a new earthquake, but not rate it until all data is received (it was not yet over in some areas).
