A zone of deep earthquakes associated with the major Cascadia subduction zone thrust fault. The 1949 Olympia (M 7.1) and 1965 Seattle-Tacoma (M 6.5) earthquakes occurred within this zone. These large earthquakes caused significant damage in the greater Seattle-Olympia region. The next big (M > 8.0) earthquake is likely to be of this type; based on paleoseismicity studies (ref 1), such events are likely to recur at intervals of 300 to 1000 years. In contrast, smaller earthquakes (M 6.0) are likely to recur at 10 year intervals.



Uh the last BIG ONE was in Jan 1700 ( recorded in Japan when a tsunami hit there) there is paleoevidence of 9.0+ magnitude...exists up here in the Seattle area.
