The Seattle Fault (and the related Tacoma Fault) is not the only source of earthquake hazard in the Puget Lowland. Other faults in the near surface continental crust, such as the South Whidbey Island Fault (near Everett), and the yet to be studied Olympia Fault (near Olympia), though historically quiescent, are suspected of generating ...
The epicenter was in the southern Puget Sound, northeast of Olympia, but the shock was felt in Oregon, British Columbia, eastern Washington, and Idaho. [6] This was the most recent of several large earthquakes that occurred in the Puget Sound region over a 52-year period and caused property damage valued at $1–4 billion.

The color-coded map shows a range of earthquake probability across the U.S. Well known high-risk areas, such as California and Alaska, are coded in dark red, denoting the highest risk.
That earthquake caused close to $100 million in damage in the most recent estimate, according to Lori Dengler, an emeritus professor in geology at California State Polytechnic University, Humboldt.
The Puget Sound faults under the heavily populated Puget Sound region (Puget Lowland) of Washington state form a regional complex of interrelated seismogenic (earthquake-causing) geologic faults. These include (from north to south, see map) the:
A map shows earthquakes above magnitude 2.5 that struck in the last week in Southern California. Quakes marked in orange occurred over a 24-hour period ending at 9 a.m. Monday, while those in ...
