University of Utah geophysicist Christine Puskas

Caption: Christine Puskas, a University of Utah doctoral student in geophysics, sits by a portable Global Positioning System (GPS) antenna near the shore of Yellowstone Lake in Wyoming. Puskas, Utah geophysicist Robert B. Smith and others have published a study based on 17 years of GPS measurements showing how Earth's crust in a large region of the West is deformed by the Yellowstone hotspot, a giant plume of hot and molten rock that powers Yellowstone's hot springs and geysers, generates earthquakes and occasionally produces catastrophic volcanic eruptions.
