Synthetic compilation map of the Yellowstone region showing mapped eruptive vents active since the last caldera collapse at 640 ka (Christiansen, 2001; Christiansen et al., 2007) (vents for the Gerrit Basalt within the second caldera are omitted on this map and are not considered in this study); earthquakes recorded between 2003 and 2008 (Smith et al., 2009; Taira et al., 2010); faults (Pierce and Morgan, 1992; Farrell et al., 2009); and ground deformation obtained from InSAR measurements during the 2004–2006 uplift episode (Chang et al., 2007). Map contours modified from Taira et al. (2010). CPM—Central Plateau Member; UBM—Upper Basin Member; BFF—Buffalo Fork Fault; CF—Centennial Fault; EGF—East Gallatin Fault; HLFZ—Hebgen Lake Fault Zone; MF—Madison Fault; ML—Mallard Lake resurgent dome; MPFZ—Mirror Plateau Fault Zone; MSF—Mount Sheridan Fault; TFZ—Teton Fault Zone; UYF—Upper Yellowstone Fault; YLF—Yellowstone Lake Fault.
