Soda Springs, ID is about 135 miles from Yellowstone. Seems a fair distance away to me.
I don’t know how accurate is the mapping of the lava pool under Yellowstone. I suspected that an undetected ‘finger’ could be seeking a way to the surface. This swarm was sudden and not similar to aftershocks. The USGS live map showed them to be spread out over a mid-sized area...As though they were independently triggrered.
The caldera is fairly large and possibly irregularly shaped. The quake in Baguio which ‘triggered’ Pinatubo is about 90 miles distant, and there was a delay of nearly a year from trigger to eruption. So this may be just an early warning. Wish I knew!
