  • 10 Dec 2015 00:17:33 PST, (34.320, -116.853), depth 3.5km, 7km N of Big Bear City, California
  • Aftershocks: so far there have been 2 aftershocks recorded, the largest M2.5. More 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 47 events of M4 or greater within 10km of today’s event, the largest was M5.3 (1992/11/27) and the most recent was M4.2 on 03 Dec 2005.
  • Nearby faults: North Frontal thrust system, eastern section (4.4 km).
