Silent earthquakes in Cascades

Szeliga et al., AGU

Evidence from GPS and seismometer data indicate that slow faulting has occurred along the plate interface deep beneath the Klamath Mountains nearly every 11 months since at least 1998. Since slow earthquakes occur throughout Cascadia, they may also be prevalent in other subduction zones worldwide. This study provides evidence for the role of fluid migration as the controlling trigger in other slow-slip faults and can be used to refine physics estimates of slow crustal movement.
