The large swarm of quakes under the lake ended 1/2 but there were 10 quakes north of the lake yesterday 1/9 including a magnitude 3.3 at 1119 MST. See the link below. I don't think I have seen that many quakes in that area before. http://www.seis.utah.edu/req2webdir/recenteqs/Maps/Yellowstone.html Graham Meech -------------- next part -------------- An HTML attachment was scrubbed...
