The 1812 Ventura earthquake (also known as the Santa Barbara earthquake) occurred on the morning of December 21 at 11:00 Pacific Standard Time (PST). The 7.1–7.5 magnitude earthquake, with a Modified Mercalli intensity scale rating of X (Extreme), along with its resulting tsunami, caused considerable damage to present-day Santa Barbara and Ventura County, California, which was at the time a territory of the Spanish Empire.[2][3] One person was killed as a result of the earthquake while another from the aftershock. The earthquake occurred just as the region was recovering from another event on 8 December the same year. Both events are thought to have been related.
