According to many scientists, the next rupture of the Cascadia Subduction Zone will spell the worst natural disaster in the history of North America…

So those interested in tremor and seismic swarms will have noticed an episode under North Vancouver Island that has been progressing for 9 days.

This kind of tectonic tremor occurs at multiple subduction zones on the planet. 'A' theory is that it's related to fluid movements in porous rocks at the subducting plate interface with the overlying crust. If it means more than that scientists haven't found data to substantiate/prove that/those conclusion(s).

Or maybe the Cascadia is about to blow and trigger the largest disaster in North American history… [PNSN, Nature]
