Future slips in this region are naturally being monitored by the Pacific Northwest Seismic Network. Should the slips continue to come early, the conversations will continue & I will do my best to update this page accordingly! Any concerns or comments, email me @

Here are the locations where I found the dates for each SSE/ETS

For the 1/24/2020-2/8/2020, I have not found any confirming data on the PNSN website so I emailed them. Here is my email and their reply.
