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
-
Only limited reports of very minor damage like broken objects from falling from shelves, cupboards etc

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 14:29 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

Structures : Low standard buildings heavily damaged, some collapse. ordinary workmanship buildings damaged, some with partial collapse. Reinforced masonry or concrete buildings damaged in some cases. A few instances of damage to buildings and bridges designed and built to resist earthquakes. Monuments and pre-1976 elevated tanks and factory stacks twisted or brought down. Some pre-1965 infill masonry panels damaged. A few post-1980 brick veneers damaged. Decayed timber piles of houses damaged. Houses not secured to foundations may move. Most unreinforced domestic chimneys damaged, some below roof-line, many brought down. Environment : Cracks appear on steep slopes and in wet ground. Small to moderate slides in roadside cuttings and unsupported excavations. Small water and sand ejections and localized lateral spreading adjacent to streams, canals, lakes, etc.
    MMI IX (Violent shaking) ?
    Structures Many low standard buildings destroyed. Ordinary workmanship buildings heavily damaged, some collapse. Reinforced masonry or concrete buildings damaged, some with partial collapse. Buildings and bridges designed and built to resist earthquakes damaged in some cases, some with flexible frames seriously damaged.
