US EditionCluster of small earthquakes rattles East Bay, USGS data shows
BART operated at reduced speeds after a series of quakes between magnitude 2.5 and 4.0 caused systemwide delays up to 20 minutes, with no reported injuries or damage.
- On Friday evening, a cluster of small earthquakes struck the East Bay near San Ramon, and Bay Area Rapid Transit ran trains at reduced speeds for safety inspections, disrupting service.
- The San Ramon area has seen notable seismic activity in recent weeks, including magnitude 3.1 and 3.0 temblors on Tuesday and 83 temblors over 10 days ending on Nov. 17.
- Timeline shows the sequence began at 7:41 p.m. with a magnitude 2.5, followed by magnitudes 2.9 and 3.8 at 7:49 and a 4.0 at 7:56, with later 3.1 and 2.9 temblors southeast of San Ramon.
- Inspections finished at 8:41 p.m., BART said safety checks concluded then and regular service resumed just before 8:45 p.m., with residual delays up to 20 minutes expected systemwide.
- Recurring clusters suggest ongoing clustering as eight days earlier three quakes rattled the region over about 100 minutes near four and five kilometers southeast of San Ramon.
