Didn't feel anything here in Walnut Creek, but when I went outside a bit ago, I saw a couple of hanging pots smashed on the ground. The 11 year old Stepson wasn't home from school yet, so it had to be the quake.
There's been about 200 aftershocks from this quake.

This however, can be called the perfect quake! Happened about 20 miles north of Pasa Robles which had major damage from last December's 6.5 quake. No reports of damage or injuries at all. Plus, this quake happened in Parkfield, which also happens to have a USGS Field Survey Office to study, Earthquakes! This area gets a 6.0 every 20 to 25 years. Scientists are saying that today's quake is going to offer a gold mine in information in regards to quake study, and could lead to an early dectection system for quakes.
