Cascadia Slow Earthquake Behaviors Modulated by Tectonic and Environmental Forcings
Past slow slip events, not yearly water cycles, control when new ones start in Cascadia.
Qingjun Meng, Zhen Liu et al.
Slow earthquakes are gentle fault movements. They release stress without shaking the ground hard. Scientists expected yearly water cycles to control when these events happen along the Cascadia fault zone. Instead, the timing better matches stress changes from earlier slow slip events, and the spots where new events start have shifted over time.
Based on patterns in historical tremor and slow slip data from Cascadia, not new physical measurements.
One fault zone, past data only, no future prediction made.
