LOS ANGELES (CBS)— Did you feel that?

Over fifty earthquakes have rattled the state of California over the last 14 hours as of Friday morning, including a 3.2-magnitude earthquake that struck 21 miles outside Moreno Valley in Riverside County at 5:03 a.m., according to the U.S. Geological Survey.

The majority of the tremors have ranged between 2-4 magnitude and have been felt as far north as San Carlos, about 10 miles south of San Francisco, and as far south as Holtville near the U.S – Mexico border.

In addition to the greater Los Angeles, San Diego, and San Francisco areas, quakes as big as over 4.0-magnitude have been recorded in Baja California within the 14 hours, according the USGS website.

The most recent one registered as a 4.1-magnitude on Friday morning at about 3:37 a.m. PDT, about 20 miles south of Guadalupe Victoria, Mexico.

Earthquake swarms are defined as when a local area experiences multiple earthquakes over a short period of time. The USGS notes that swarms can last as short as a day or as long as several months.

Of course, earthquakes — even clusters of them — are not unusual for the seismically-active state, but the swarm does end a period of relative quiet for the region.

The U.S. government recently warned that a major earthquake could disrupt the local labor market and cost Los Angeles as much as $213 billion in losses.

    Yeah, it’s called HAARP and Chemtrails. If we do get the big one make sure we send the bill to our gov.

    I’d rather have a bunch of these small quakes than a giant one!

    It wasn’t earthquakes….it was the thundering of millions of feet running to see Harry Potter at once!

    Media scare tactics.. Earthquakes in California, below 4? Front page news? Child please

  6. R.U. Serious says:

    A swarm is localized, originating from one location. You can’t take the total for the entire state, with different epicenters and call it a swarm. This is at best hype, at worst, irresponsible.
