Six sizable earthquakes have struck the state of Washington within the last two weeks. Four occurred within the last twenty-four hours. Washington is territory to five highly active volcanoes in the Cascade Range; Glacier Peak, Mount Adams, Mount Rainier, Mount Baker, and Mount St. Helens. This incredibly seismically active region is the northernmost point of the Cascadia Subduction Zone.
The Cascadia Subduction Zone is synonymous with producing some of the largest and most powerful earthquakes in the world, and seismologists expect the infamous Cascadia seismic event to strike in this region. Cascadia has been predicted to be a magnitude 9.0 earthquake and trigger a tsunami that could reach hundreds of miles. Historically, there have been 200-600 years between events of this magnitude in the past. The last Cascadia event occurred on 26 January 1700.
The earthquakes documented below have taken place in a region accustomed to seismic activity, and while their seismicity is being evaluated, there's no need to panic. The reported earthquakes have been documented by USGS and Pacific Northwest Seismic Network, two of the most credible and globally-recognized seismic activity monitoring systems. UTC is an abbreviation for Coordinated Universal Time.
