#EarthquakeWarning After 290 Earthquakes In 104 Hours In So. Calif. ‘Swarm’

The first one hit around 4 a.m. Then came another, and another… and then, many more.  Between Monday morning and noon Friday, some 290 earthquakes had shaken the Salton Sea, seismologists tell Patch. The “swarm,” as it’s being called, is one of only three in recorded history at the area, lasting much of the week. Previous occurrences happened in 2001 and 2009.Of the quakes to strike the region– a seismic zone near the southernmost tip of the infamous San Andreas Fault– officials say 17 were greater than a magnitude-3 and 97 were greater than a magnitude-2. The three largest included:Los-Angeles-Hotels-With-The-Best-Views-THE-STANDARD-DOWNTOWN-LA

  • M4.3, Monday at 7:31 a.m. PST
  • M4.3, Monday at 8:23 p.m. PST
  • M4.1, Monday at 8:36 p.m. PST

But though the swarm appears to be tapering off Friday, that doesn’t mean that we’re in the clear quake-wise, officials warn. The California Office of Emergency Services even issued an “earthquake advisory” to remind Southern California residents to always be prepared for temblors.


This comes after the U.S. Geological Survey found the Salton Sea swarm may add stress to the San Andreas Fault, by the slightest amount, potentially increasing the likelihood of an earthquake of magnitude-7 between now and Oct. 4.
