Earthquake near Ramona, just a small one

It is not unusual to feel the occasional quake where we live just north east of San Diego. Usually the epicenter is far to the east, near or in the desert. In fact there are small quakes all over California and Nevada all the time. So when I heard the rumble and felt a little shudder about an hour ago, I was quite surprised to find out how close to home this one was.

Red indicates an event in the last hour. This one was a magnatude 2.8 event — pretty mild. I would have slept through it had I been asleep.
