What is an Earthquake Swarm?
An earthquake swarm is a sequence of many earthquakes occurring in the same area over a relatively short period, without a clear mainshock-aftershock pattern. Unlike typical earthquake sequences, swarms don't have a single large earthquake followed by smaller aftershocks - instead, the earthquakes are more similar in size.
The Calaveras Fault Connection
The Santa Clara area is located along the Calaveras Fault, which is known for producing earthquake swarms. The San Ramon/Danville area experiences noticeable swarm activity every few years. While these swarms can be unsettling, they typically consist of small earthquakes that cause no damage.

Should You Be Concerned?
Most earthquakes in this swarm are too small to feel. Earthquake swarms are a normal part of seismic activity in the Bay Area and do not necessarily indicate a larger earthquake is coming. However, they're a good reminder to stay prepared.
