Depth (Hypocenter) : 8.8 km  (5.5 miles)
Geo-location(s) :
2 km (1 miles) N (1°) from El Cerrito, CA
2 km (1 miles) SE (137°) from East Richmond Heights, CA

7 km (4 miles) NNW (341°) from Berkeley, CA   


 

Update 14:55 UTC
– El Cerrito police reported not having received any damage or injury reports.
– An aftershock was reported near the epicenter about 30 minutes later.
– Luckily, still NO reports of damage or injuries

Update 14:41 UTC
BART trains were halted temporarily and service soon resumed.

Update 14:40 UTC
Coordinates released by the U.S. Geological Survey place the epicenter at the Mira Vista Golf and Country Club along the Hayward Fault, which runs through the East Bay hills. The Hayward Fault is considered by many seismologists to be a prime candidate for a major earthquake. The 2010 update of the report, “On Shaky Ground,” by the Association of Bay Area Governments, reported that there’s an estimated 62 percent probability of a destructive quake of magnitude 6.7 or greater in the Bay Area in the years 2003-2032.

Update 14:32 UTC

Update 14:29 UTC
– Based on the current reported shaking values, earthquake-report.com does not expect to see major damage during this earthquake. We do not exclude cracks in walls, objects falling from shelves etc.

Update 14:24 UTC
– The fault line were today’s earthquake took place is the same as the one which was responsible for a number of other quakes from the preceding months.

Update 14:10 UTC
– 27,000 people will have experienced a strong shaking (East Richmond Heights and El Cerrito)
– 276,000 people a moderate shaking (MMI V) (Kensington, Albany, El Sobrante and Richmond)

– This earthquake will probably not lead to any damage but it surely must have been scary so early in the morning

Moderate shallow earthquake 2 km from Berkeley, San Fransisco Bay area

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:  Earthquake-Report.com does not expect damage or injuries based on the depth and the magnitude of this earthquake.

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.
