More Yellowstone Lake Earthquake Swarm Images
Map showing location of all earthquakes in the Yellowstone National Park area from 1973 to Jan 7, 2009. The red circles
are the Yellowstone Lake swarm earthquakes. All other earthquakes are shown in gray. The yellow stars are known
volcanic vents. The large gray star is the location of the M 7.5 Hebgen earthquake in 1959. The park boundary is
outlined in green and the caldera is outlined in black. The earthquake locations where calculated using techniques described in
Farrell, J. M., R.B. Smith and S. Husen, 2008, Earthquake swarm identification and b-value mapping of the Yellowstone
volcanic-tectonic system, J. Vol. Geotherm. Res, (submitted).
