I put this in chat not knowing if this is the correct spot. We probably have members in the Portland OR area too, this is closer to the mountain. There were posts on FR recently regarding micro-quakes. Todays quakes were larger, 2.8 richter compared with about 1 on richter.
I was pretty young when that mountain went up last time.
I seem to recall a bunch of tiny quakes happening just like mentioned.
All small 1 or 2 on the richter quakes with a few spiking to 5 or so.
Will have to look it up, but that mountain is unpredictable.
Hope everyone out there stays safe.
