Scientists discovered a crack under the sea off Vancouver Island, NFZ in Cascadia region, that could alter Pacific subduction.

The Cascadia Subduction Zone is unusually quiet for a megathrust fault. Spanning more than 600 miles from Canada to California, the fault marks the convergence of the Juan de Fuca and North American ...
