The earthquake (6.5 Idaho) was centered in the Yellowstone Magma Chamber
~~~~~~~~~~~~~~~~
uh-oh..rememeber BDA’s worries??
Checked the USGS map and the Idaho quakes (there were about four aftershocks looked like 3.0 or so) are about 125 miles directly West of Yellowstone.
Information I've seen on the magma chamber shows it extending 90-100 miles to the SW of Yellowstone, so the quakes are close but not truly centered on the chamber.
Since we have a clear view of the North edge of the caldera rim from The Homestead's kitchen window, I've got a whole lot more than academic interest in Yellowstone.
Didn't notice anything at all when that quake hit, but guess they're so common around The 'Stone we just tune the little ones out.
If that bugger ever does do something serious I think you'll hear me without the 'net.
First thing that came to mind.
