Cascadia has been an anticipated event in California along the San Andreas Fault and coastline for decades – and it’s no wonder. The coastline parallels one of the most seismically active zones in the world. While Washington, Oregon, and California face unparalleled side effects from a Cascadia event, the force can only be imagined.
In 1700, a magnitude 8 - 9 earthquake hit the Cascadia Subduction Zone and created a ‘Cascadia’ event like the one anticipated to be repeated by seismologists and geologists.
While earthquakes along the San Andreas Fault area are normal, a Cascadia event of this magnitude (pun intended) is anticipated. Historically, Cascadia events on the West Coast of the United States occur every 500 years.
There’s no need to panic since there’s no way to predict a Cascadia event, and there’s nothing to be done to avoid one. Regions posed by this threat are used to seismic activity and know that the best thing to do is to be prepared. Having an evacuation plan in relation to your location along the coastline/San Andreas Fault Line is the first and best course of action to have in place.
California, Oregon, and Washington have a new ‘MyShake’ app system that acts as an early earthquake detection system along the San Andreas. Since the earthquakes documented below have taken place in a region accustomed to seismic activity, there is no need to panic. The reported earthquakes have been documented by USGS, one of the few credible and globally-recognized seismic activity monitoring systems. UTC is an abbreviation for Coordinated Universal Time.
