The shock occurred on the Calaveras Fault near Coyote Lake in Santa Clara County, California and resulted in a number of injuries, including some that required hospitalization. Most of the $500,000 in damage that was caused was non-structural, but several businesses were closed for repairs. Data from numerous strong motion instruments was used to determine the type, depth, and extent of slip. A mild aftershock sequence lasted throughout the remainder of the month that was of interest to seismologists, especially with regard to fault creep, and following the event, local governments evaluated their response to the incident. ==Tectonic setting== Several strands of the San Andreas Fault System in the eastern region of the San Francisco Bay Area are the Hayward–Rodgers Creek and Calaveras Faults. The Hayward Fault exhibits fault creep, but it also has potential for large earthquakes, like the 1868 M7 Hayward earthquake that occurred on its southern segment. The northern Calaveras Fault meets the Hayward Fault near the Calaveras Reservoir and can also produce large earthquakes, but the central and southern segments might only produce smaller events as well as fault creep. An exception to this is a ~M6.5 shock that occurred in 1911. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1979 Coyote Lake earthquake」の詳細全文を読む スポンサード リンク
