With the dramatic earthquake increase in Oklahoma the past 5 years, the USGS has produced a map showing the chances of damage for the year 2016. This forecast covers the 48 states. California remains an area of concern with parts of Oklahoma having a comparable threat.
Western Wyoming is an area of some concern(not to the extent of CA and OK). However the combination of the Yellowstone Caldera and known faults near the WY/ID border, raises the threat levels. This includes the Star Valley region.
