Cascadia event will be staggeringly larger than others Nisqually vs. Cascadia MAGNITUDE:

Geologic forces that shaped many of Washington’s beautiful features also give the state one of the highest earthquake hazards in the nation. The potential impacts of this hazard were demonstrated in 2001 by the Nisqually earthquake, which caused hundreds of injuries and inflicted damage serious enough to prompt federal disaster declarations in 24 counties, but this was not the most damaging earthquake we can expect.
