It has been three centuries since the last Cascadia Subduction Zone earthquake, which happened in January 1700. People wonder if the 'Big One' is coming soon. KOMO News has a report on an article in the Bulletin of the Seismological Society of America with results of ocean-bottom seismometer monitoring of the Cascadia Subduction Zone. The lack of interplate seimicity indicates that the dangerous Cascadia fault zone is completely locked. The release of this storing energy in the lock zone may lead to a big earthquake in the PNW.

The PNSN reduces risk within the states of Washington and Oregon by
- monitoring ground motions within the region in order to better understand earthquake and volcano hazards and their impacts on the physical, economic, political, and social environment,
- providing the most accurate information about earthquakes and volcanoes as rapidly as possible to public officials, the public, and for education, and
- advocating comprehensive and cost-effective measures for reducing the harmful effects of earthquakes and volcanoes.
