M 2.7 event east of Winthrop

Post by Marjorie and Sam » Fri Sep 13, 2024 10:14 am

The USGS latest earthquakes page is reporting a M 2.7 other event 15 km east of Winthrop this morning. The depth is -0.8. I thought this was very interesting. Did anyone feel it? I suppose -0.8 means it was above ground but I don't know.

That is interesting. The data I'm reading on the USGS Earthquake page now indicates an M 2.6 (M1) earthquake 14 km E of Winthrop registering 0.4 km depth at 9:12 AM. It now has been "reviewed" as accurate by scientific monitors at the University of Washington.

4 km would indicate a shallow quake. There was one respondent who felt it.

Please, any geologists/seismologists out there feel free add more information.

Do you know the approximate time? I guess our giant dead pine that came down yesterday with a really big boom may not count.

No Pearl, as far as I can tell this was up the North Fork of Beaver Creek but I know those giant trees can shake the ground when they come down.
I was curious about the negative number for the depth, further reading I see it is a result of the way they figure level ground for a given spot. Jim's right it was very shallow.
