The west coast is shaking again.  In recent weeks we have witnessed so much seismic activity along the portion of the Pacific Ring of Fire that sits directly along the California coastline.  There had been hope that the shaking would settle down, but instead it appears to be accelerating.  As you will see below, there have been 321 earthquakes in the San Francisco area within the past 7 days.  If I was living in northern California, that would definitely get my attention.  Scientists have warned us over and over again that "the Big One" is inevitably coming, and almost every day there are more reminders of this.  In fact, San Ramon was just hit by a swarm of more than 30 earthquakes on Monday morning…

A 4.2 earthquake struck near San Ramon Monday morning, following a 3.8 quake amid a string of over 30 temblors in the area, U.S. Geological Survey said.

The 4.2 quake struck at 7:01 a.m. and followed a string of quakes that began with a 3.8 at 6:27 a.m. Dozens of earthquakes have followed.

USGS said the 4.2 quake was about 9.4 km in depth.

A magnitude 4.2 quake is quite significant.

The shaking that it caused was so extensive that people living in the heart of San Francisco actually felt "windows rattling"…

Residents in San Francisco's Glen Park and Nopa neighborhoods reported rumbling and 'windows rattling' during the quake, and public transportation throughout the area was also affected by the swarm, according to the San Francisco Chronicle.

The moderate quake even activated the National Tsunami Warning Center, however, officials said there was no danger of a major wave hitting the Bay Area.

Of course this was not an isolated incident.

According to the USGS, this latest earthquake swarm was "a continuation" of a pattern of heightened activity that the region has been experiencing since last November…

ABC7 Eyewitness News spoke with the USGS Monday morning, and they say this is a continuation of the swarm of quakes the area has been experiencing.

On Friday, the area saw its first earthquake in several weeks, but there have been dozens of quakes since November.
