As seismologists review available data, they may revise the earthquake’s reported magnitude. Additional information collected about the earthquake may also prompt U.S.G.S. scientists to update the shake-severity map.
Aftershocks in the region
An aftershock is usually a smaller earthquake that follows a larger one in the same general area. Aftershocks are typically minor adjustments along the portion of a fault that slipped at the time of the initial earthquake.
Quakes and aftershocks within 100 miles
Aftershocks can occur days, weeks or even years after the first earthquake. These events can be of equal or larger magnitude to the initial earthquake, and they can continue to affect already damaged locations.
Source: United States Geological Survey | Notes: Shaking categories are based on the Modified Mercalli Intensity scale. When aftershock data is available, the corresponding maps and charts include earthquakes within 100 miles and seven days of the initial quake. All times above are Pacific time. Shake data is as of Monday, Aug. 12 at 12:25 p.m. Pacific time. Aftershocks data is as of Monday, Aug. 12 at 1:05 p.m. Pacific time.
SAN RAMON, Calif. (KGO) — An earthquake with a preliminary magnitude of 3.4 struck near San Ramon at 11:21 p.m. Sunday, the U.S. Geological Survey said.
USGS said the tremor was about 8.4 km in depth.
According to the Geological Survey, people typically report feeling earthquakes larger than about magnitude 2.5.
The closer to the surface an earthquake occurs, the more ground shaking and potential damage it will cause.
No injuries have been reported.
This is the latest quake in San Ramon, which has seen multiple strings of tremors in the past several months.
