Swarm Numbers

  • As of 17 Jul 2022, 09:52AM PDT, we have recorded 44 events in the swarm (within a 20 km radius, and counting 60 days before the largest event). The smallest event is magnitude 0.7. Many of the smaller events are still being analyzed and will be gradually added to the catalogue.
  • More activity is expected in the next few days, swarm activity in Southern California can continue for hours, days, weeks, months or years. For more information on swarms please see our Swarm page.

Historical Seismicity

  • Since our records began in 1932 we’ve had 19 events of M4 or greater within 10km of today’s event.
  • The largest historic event was M4.9 on 2001/02/02.
  • The most recent historic event was M4.0 on 27 Aug 2021.


  • CFM fault associations: most likely Lake Isabella lineament (61%). Alternates: Not associated with a CFM modeled fault (15%), Other CFM faults (24%).*

Additional Information

Below are the waveform data associated with this event, as recorded in our Live Seismograms Feed.

*Earthquakes can occur both near or on major known faults, and in places where no clear fault zones are known. Using the statistical method of Evans et al. (in prep. 2019) the location and focal mechanism of this earthquake suggest the above association with modeled faults in the Community Fault Model (CFM) provided by the Southern California Earthquake Center (SCEC) and Harvard University. Note that the CFM fault association may be different from the nearby faults list. Differences may arise due to different fault databases, and because the CFM fault association uses the hypocenter with relation to subsurface 3-dimensional fault orientation models, while the nearby faults list utilizes mapped surface traces as they relate to the epicenter.

CFM Fault: SCEC CFM 5.0 Fault name and closest segment if available; The CFM is maintained by Harvard University, Dept of Earth & Planetary Sciences.

Probability: The probability in percent the earthquake is associated with this fault.
