Update : Earthquake-Report.com thanks the people from the Bay Area in sending their I Have Felt It reports. MMI numbers are good but the description of what people exactly felt is always more informative. (see below for the I Have Felt It reports)

Update:  We have no reports of any serious damage or injuries and we do not expect to find them neither. Falling objects and moments of fear are the main disturbances of this earthquake.

Update:  We just received a report from Portland, Oregon, that somebody felt this earthquake as a very weak shaking.

Update:  As most of the people in this part of California know, weak aftershocks can occur after such a mainshock.

Update:  We congratulate USGS for their very good theoretical intensity strength calculation. As they have expected, only the direct epicenter area reports a max. MMI V intensity (moderate shaking).

Update:  Most of our readers are reporting 2 strong jolts from a couple of seconds

Update: The earthquake occurred almost below a known fault line.

Update: As can be seen in the I Have Felt It report (more to come) a lot of people were frightened from the jolts

Update : USGS expects that 88,000 people will have experienced a Moderate MMI V shaking. 901,000 people will have felt a light shaking.
