A 3.9-magnitude earthquake has been recorded in the Los Angeles area, the US Geological Survey reports. Though the quake was shallow, residents across the basin say they were woken up by the tremor.

The shallow earthquake occurred just one mile from View Park-Windsor Hills, California, at 4:07 am on Sunday morning.

The quake, which struck at a depth of 5.6 miles, was classified by the USGS as “light”. However, it was still felt over a wide area of the LA basin.  

It was the second earthquake in less than a month along the Newport-Inglewood fault. A magnitude-3.5 quake hit the same area on April 12.

The Los Angeles Fire Department briefly went into “earthquake mode.” As its helicopters surveyed more than 470 square miles in the area and all 106 fire stations conducted safety checks, the alert was lifted.

California is an active earthquake location, owing to its unsettling geographical position, with tectonic plate motions underneath.

The current seismic period is, however, a relatively calm one. With not many shocks reaching even magnitude 3 in recent months, because “far less” energy is being released in earthquakes than it is being stored from tectonic plate motions.

However, this “won’t last forever”, according to University of Southern California earth sciences professor James Dolan.

At some point, we will need to start releasing all of this pent-up energy stored in the rocks in a series of large earthquakes,” Dolan said.

The earthquake could spark a “super cycle,” meaning “a flurry of other Big Ones, as stresses related to the original San Andreas fault earthquake are redistributed on other faults throughout Southern California,” he said in late April.

  1. “It was the second earthquake in less than a month along the Newport-Inglewood fault.”

    They talk about the San Andreas fault. If THIS b#tch goes, WAY more death & destruction!!!

    I lived within a few miles of it much of my life.

    Not anymore.

    1. look at that sizemograph plot,
      no buildup, no aftershocks.
      THAT WAS A BOMB!!!

      and what’s with the depth!!
      (or lack of it)
