Yellowstone movement continuing. I've been watching this slow motion swaying of a number of seismographs in the Yellowstone area. Namely Dillon, MT, Flagg Ranch, WY, and Fox Creek, WY. I've put pointers on them to outline the area moving.
The movement is very long period swaying, not the herky jerky typical of earthquakes and other disturbances. These movements occur over the spans of hours.
Anybody got ideas?
