Cascadia subduction zone awakens, 11 earthquakes hit off Oregon coast

Experts warn the Cascadia subduction zone is one of the most dangerous and powerful areas in the world in which a megaquake may occur

(INTELLIHUB) — Eleven earthquakes between the magnitudes of 2.8 and 5.6 occurred off the coast of Oregon Tuesday on the Juan de Fuca tectonic plate six miles below sea level.

The recent uptick in activity is bothersome due to the fact the entire 650-mile-long faultline is one of the most dangerous in the world and is expected to cause a magnitude 9 or greater earthquake in the future which a FEMA official has warned would wipe out everything west of Interstate 5.

No tsunami warning was issued for any of Tuesday’s quakes.
