Lisa Morgan is a scientist emeritus, former senior research geologist, for the U.S. Geological Survey, whose focus is on the geology and geophysics of volcanic terrains.
She has studied the Yellowstone hot spot and Yellowstone Lake for more than 20 years, and her research focuses on the geology and associated hazards in Yellowstone Lake, physical processes associated with eruption of the post-glacial (100 m diameter) hydrothermal explosion craters, the physical characteristics associated with emplacement of the 0.64-Ma Lava Creek Tuff and development of the Yellowstone caldera, and emplacement of post-caldera rhyolitic lava and pyroclastic flows on the Central Plateau.
