AB: The 1914 Reno earthquakes are instructive events that serve as distinct warnings of future potential seismic damage. The earthquakes occurred in two major groups, one in February and one in April. The largest February event occurred mid-morning on the 18th and frightened people enough to cause them to rush into the streets in Reno, Sparks, and Virginia City. This earthquake caused significant nonstructural damage in Reno. The largest event (~M6.3 ±0.3) occurred on April 24th and followed the third largest event (a foreshock) by 28 hours. The main earthquake was a nighttime event and was felt from Berkeley, CA to Winnemucca, NV. Again people ran to the streets and there was nonstructural damage, but this time it was reported as far away as the Great Valley in California. The first detailed intensity maps for these earthquakes are based on 106 accounts we have gathered, and were used to estimate magnitudes. Some accounts hint at the possibility that two or more earthquake sources may have been active during this sequence; however, the main events appear to be located beneath Reno.
