With a moment magnitude of 5.6 and a maximum perceived intensity of VII ( Very strong) on the Mercalli intensity scale, it was the largest earthquake in the Pacific Northwest since the Elk ...
Pacific Northwest Seismic Network. The Pacific Northwest Seismic Network, or PNSN, collects and studies ground motions from about 400 seismometers in the U.S. states of Oregon and Washington. PNSN monitors volcanic and tectonic activity, gives advice and information to the public and policy makers, and works to mitigate earthquake hazard.

A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.
The Cascadia subduction zone is a 960 km (600 mi) fault at a convergent plate boundary, about 100–200 km (70–100 mi) off the Pacific coast, that stretches from northern Vancouver Island in Canada to Northern California in the United States. It is capable of producing 9.0+ magnitude earthquakes and tsunamis that could reach 30 m (98 ft).
