This morning brought a literal shake-up for Bay Area riders, as BART warned that an earthquake had hit its service area and that trains would be running at reduced speeds while safety inspections were underway. Trains kept moving, but under slow orders, and passengers were told to expect residual delays of up to 20 minutes systemwide while workers visually checked tracks and infrastructure for any damage.
What BART Told Riders
In an early post today, BART said an earthquake had occurred in the area it serves and that trains were running at reduced speeds while crews conducted safety track inspections. Riders were advised to expect residual delays of up to 20 minutes across the system, according to SFBART. The agency pushed the update through its X feed and rider-notification channels while inspectors were out checking tracks.
Attention Passengers: An earthquake occurred within the area serviced by BART. Trains are running at reduced speeds while we complete safety track inspections. Please expect residual delays of up to 20 minutes systemwide.

How BART’s Earthquake Systems Work
BART is an early adopter of the ShakeAlert earthquake early-warning system and uses automated responses that slow trains to roughly 27 mph when shaking passes key safety thresholds, then require visual track inspections before regular service can resume, according to BART. The procedures are designed to cut the risk of derailment and give crews time to look for any infrastructure damage.
Where The Quake Hit
Data from the U.S. Geological Survey, reported by the San Francisco Chronicle, show the largest temblor struck just southeast of San Ramon on Monday morning at roughly magnitude 4.2 and was one of several jolts in a brief swarm felt across the East Bay. SFGate reported the strongest movement measured about 4.3 and said the series produced eight quakes in that window, with no immediate reports of major damage.
Rider Impact And Tips
Commuters should build in extra travel time and check the latest line-specific updates on the advisories section of BART or in the agency app. Riders may want to consider alternate routes and be ready for sporadic slow orders as inspections continue, and BART has said it will post updates as crews clear tracks…
