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.READ MORE: Fire Risk High As Winds Whip Up In Fontana

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.MORE NEWS: Double Jeopardy Claim Leads To Indefinite Hold On Retrial In Michael Avenatti Case
