05 Jun 2024 M4 events
- M 4.3 05 Jun 2024 01:42:42 PDT, (32.397, -115.192), 40614631
- M 4.6 05 Jun 2024 04:58:40 PDT, (32.422, -115.180), 40614823
Aftershocks
- As of 05 Jun 2024, 06:23AM PDT, there have been 2 aftershocks recorded.
- The largest was M2.6 (smallest M2.3).
- More aftershocks may be expected in the next few days, the largest expected is approximately 1 magnitude unit smaller than the mainshock.
- There is a small chance (about 5%) that a larger quake could occur, with the likelihood decreasing over time.
Possible Foreshocks
- There were 11 events during the 3 days prior to the earthquake (within a 10 km radius).
- The largest was M4.3 (2024/06/05).
Historical Seismicity
- Since our records began in 1932 we’ve had 88 events of M4 or greater within 10km of today’s event.
- The largest historic event was M7.2 on 2010/04/04.
- The most recent historic event was M4.3 on 05 Jun 2024.
Faults
- CFM fault associations: most likely Not associated with a CFM modeled fault (83%). Alternates: Cierro Prieto fault (10%), Other CFM faults (7%).*

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.
