Earthquake swarm rattles California region facing a 75% chance of a major quake,Moreover, one geophysicist has urged Americans to prepare for a so-called mega-quake in California, pointing to a trend of major earthquakes moving north from South America

A swarm of earthquakes has been detected in Northern California, just miles from what experts call ‘America’s most dangerous’ fault line.

The US Geological Survey has monitored more than two dozen minor seismic events over the last day, all taking place within 30 miles of the San Andreas Fault.

The strongest and most recent was a magnitude 2.7 quake that took place at 10.14am ET Monday morning in The Geysers, a large geothermal field north of San Francisco known for frequent swarms of tiny tremors.

Several other noticeable quakes were detected much closer to the San Andreas, near several populated communities around the San Francisco Bay Area.

This includes a trio of magnitude 2.5 earthquakes near Berkeley, Concord and Gilroy, shaking areas just 10 to 20 miles from the massive fault.

All of the quakes have been considered minor, but the fresh activity along a 150-mile stretch of the San Andreas comes after scientists warned there is nearly a 75-percent chance of a major earthquake erupting in the Bay Area by 2055.

In September, USGS increased the risk of a major disaster in Northern California from 72 to 74.1 percent within the next three decades.

Moreover, one geophysicist has urged Americans to prepare for a so-called mega-quake in California, pointing to a concerning trend of major earthquakes moving north from South America over the last year.
