Lisa A. Morgan
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.
Science and Products
The dynamic floor of Yellowstone Lake, Wyoming, USA: The last 14 k.y. of hydrothermal explosions, venting, doming, and faulting
Hydrothermal explosions are significant potential hazards in Yellowstone National Park, Wyoming, USA. The northern Yellowstone Lake area hosts the three largest hydrothermal explosion craters known on Earth empowered by the highest heat flow values in Yellowstone and active seismicity and deformation. Geological and geochemical studies of eighteen sublacustrine cores provide the first detailed syn

Fossilized diatoms of siliceous hydrothermal deposits in Yellowstone National Park, USA
The study of eukaryotic extremophiles is relatively novel, and, therefore, documentation of the structure and function of micro-organisms in continental hydrothermal systems globally is limited. In this study, we investigate fossil diatoms in siliceous hydrothermal deposits of the Upper Geyser and Yellowstone Lake hydrothermal basins in Yellowstone National Park, and utilize preserved diatom assem
