San Francisco: A minor earthquake with a magnitude of 4.0 shook the San Francisco Bay Area on Monday evening, according to the United States Geological Survey (USGS).

The tremor was recorded at 7:46 p.m. Pacific Time, with its epicentre located approximately three miles northwest of Dublin, California, USGS data showed. Initial reports measured the quake at a magnitude of 4.0, though seismologists may revise this figure as they continue to analyse the data. Updates may also be made to the agency’s shake-severity map as additional information becomes available.

There were no immediate reports of injuries or property damage following the quake. However, residents in the affected areas took to social media to describe the brief but noticeable shaking.

Dublin, like much of the San Francisco Bay Area, is prone to seismic activity due to its proximity to the San Andreas Fault. The region has a history of significant earthquakes, including the devastating 1906 San Francisco earthquake, which measured 7.9 in magnitude and is considered one of the deadliest in American history. The disaster claimed an estimated 700 to 3,000 lives and led to the development of stricter building codes and safety regulations that continue to shape the city's infrastructure.

The 1906 earthquake remains one of the largest recorded in California, tied with the 1857 Fort Tejon earthquake. Meanwhile, the most powerful earthquake ever recorded in the United States was the Great Alaskan Earthquake of 1964, which struck near Anchorage. With a magnitude of 9.2, it triggered widespread destruction and deadly tsunamis along Alaska’s southern coastline. It remains the second-largest earthquake ever recorded globally.
