While dates for Episodic Tremor and Slip (ETS, aka slow-slips) events in the northern region match up with those listed on the Pacific Northwest Seismic Network’s (PNSN) Tremor Logs, there currently aren’t compatible logs for the central (Siletzia) region. These dates are pulled from the PNSN Tremor Map and represent patterns consistent with slip events in the north and south. I’ll keep an eye out for date verification publications (likely coming out from the Cascadia Region Earthquake Science Center (CRESCENT) in the near future).
