  • 25 Mar 2023 23:20:45 PDT, (35.790, -116.850), depth 0.4km.
  • 48km E of Trona, California

Aftershocks

  • As of 26 Mar 2023, 09:41AM PDT, there has been 1 aftershock recorded, M1.5.
  • 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.

Historical Seismicity

  • Since our records began in 1932 we’ve had 4 events of M4 or greater within 10km of today’s event.
  • The largest historic event was M4.8 on 1953/11/24.
  • The most recent historic event was M4.1 on 22 Aug 2017.

Faults

  • CFM fault associations: most likely Not associated with a CFM modeled fault (96%). Alternates: Black Mountain fault (3%), Other CFM faults (1%).*
  • Nearby faults: Panamint Valley fault zone, Brown Mountain section (8.2 km).**

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.
