Multiple earthquakes hit Bay Area as Super Bowl week begins — should fans be worried or not?

It was literally a shaky start to Super Bowl week in the San Francisco Bay Area on Monday morning. A series of earthquakes rattled the region, including a **magnitude 4.2 tremor just as fans, teams, and media were starting to arrive ahead of Super Bowl LX festivities. Thankfully, there are no reports of major damage or serious injuries but residents and transit authorities definitely felt it.

Multiple earthquakes shook the region early Monday

The United States Geological Survey recorded multiple earthquakes near San Ramon, California, early Monday. The largest was measured at magnitude 4.2 around 7:01 a.m., and dozens of smaller quakes occurred before and after it in roughly a 90-minute span.


Seismic activity ranged from around 2.5 up to 4.2 magnitude with the earliest noticeable tremors starting around 6:27 a.m. before the strongest hit. Locals reported feeling shaking in areas as far as Oakland, Richmond, San Leandro and eastern parts of San Francisco.


The quakes happened at the very start of a massive week in the Bay Area. With Super Bowl LX scheduled for Sunday at Levi’s Stadium, thousands of fans, media and NFL personnel are already in the region for events and festivities and many felt the shaking.

Despite the timing, there’s no indication these earthquakes have affected official Super Bowl operations or event schedules so far.


While there have been some minor incidents like items falling off store shelves but no serious damage or injuries have been reported from the quake swarm.

Local transit officials, including Bay Area Rapid Transit (BART), slowed trains temporarily to conduct track safety inspections after the tremors. Riders were warned to expect delays of up to 20 minutes systemwide while crews checked infrastructure.

Why this happened: normal Bay Area seismic activity

The Bay Area sits on a tangle of active fault lines, including the Calaveras Fault and earthquake swarms aren’t unusual for the region. Experts say clusters of smaller quakes often occur without indicating a major quake is imminent.

This particular swarm fits a pattern, San Ramon and the broader East Bay have seen frequent small tremors in recent months. Scientists note this kind of activity tends to happen in sequences and is part of the area’s ongoing seismicity.

For locals, the shaking was a noticeable Monday morning jolt and for visitors here for Super Bowl week, it was an unexpected experience. But so far, everything from transit systems to event plans remains operational and intact.

If anything, the earthquake activity serves as a reminder that being in the Bay Area means living with seismic risk even during one of the biggest sports weeks of the year.
