Historic Earthquakes
Vacaville, California
1892 April 19 10:50 UTC
Magnitude 6.4
This earthquake caused severe damage at Allendale, Dixon, Vacaville, and Winters. Property loss was estimated at $225,000, and one fatality was reported.
At Allendale, between Vacaville and Winters, several buildings in the area collapsed, shifted off their foundations, or were wrenched apart. Ground fissures formed near Allendale, which suggests possible faulting. At Vacaville, almost all brick structures were destroyed, many frame buildings were impaired, and chimneys were twisted or knocked to the ground. Similar damage was reported from Winters (Yolo County). Although damage in general was less serious in Dixon, many school buildings were almost ruined. MM intensity VIII or higher was observed over an area of 1,100 km2. Felt north to Redding, east to Virginia City, Nevada, and south to Salinas and Fresno.
