  Locating earthquakes in the Yellowstone region Release Date: August 30, 2021 Ever wonder how seismologists determine the location of an earthquake in Yellowstone?  It’s an intricate process, but thanks to experienced scientists, up to thousands of earthquakes are located in the Yellowstone region every year! Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Jamie Farrell, assistant research professor with the University of Utah Seismograph Stations and Chief Seismologist of the Yellowstone Volcano Observatory.
