The 1892 Vacaville–Winters earthquakes occurred in northern California as a large doublet on April 19 and April 21. Measured on a seismic scale that is based on an isoseismal map or the event's felt area, the 6.4 MLa and 6.2 MLa events were assigned a maximum Mercalli intensity of IX (Violent), and affected the North Bay and Central Valley areas. While the total damage was estimated at between $225,000–250,000, one person was killed, but there are no reports on how many people may have been injured. No surface faulting was observed as a result of either strong shocks.
