Cascadia Subduction Zone Tremors: 36,377 in 2018

In 2018, the Cascadia Subduction Zone saw 36,377 Episodic Thrusts & Slips (ETS). These tremors are different from earthquakes, which are generally more sudden, and that of other, shallower faults, which can be generated from the pressure buildup of magma sitting under Cascadia’s many volcanoes along the Pacific Ring of Fire.
