Mw 7.0 Santa Barbara Channel, California

updated 24 January 2023

report

On 21 December 1812 a major earthquake occurred at the Santa Barbara Channel, California. The seismic event occurred around 7:00 UTC and had an estimated moment magnitude (Mw) 7.0.

The estimated primary trigger of this seismic event is critical lunar geometry from 17 to 19 December 1812.

From 17 to 19 December 1812 critical lunar geometry occurred involving Mars, Jupiter, Venus and Uranus, which converged with a lunar conjunction (Full Moon) on 18 December and a lunar conjunction with Saturn on 19 December.

The earthquake was preceded by a major seismic event to the east two weeks earlier.
