The earthquake which occurred 20 km northwest of Bishop, California on 23 November 1984 continued the series of moderate magnitude earthquakes which have occurred in the area during the last decade. Many of the earthquakes in this series have generated significant strong motion records. The 23 November 1984 event occurred to the southeast of the May 1980 Mammoth Lakes sequence of four ML > 6 earthquakes. The accelerations from the 1984 earthquake are all significantly less than were recorded in 1980, although one station in this earthquake was located almost directly over the earthquake origin.
