Prehistoric Earthquakes
Earlier earthquakes have been detected by trench exposure and associated carbon dating. Combined with the historic record, the last five major events were in 1315, 1470, 1630, 1725, and 1868, which have intervals of about 140 years (note that 2008 is 140 years from the major 1868 event).
