Ground Deformation Survey in Yellowstone National Park

Annual Ground Deformation Survey using a Global Positioning System

The survey is a collaborative effort involving YNP staff, geologists, GPS specialists, and students.

Project Objectives

  1. To demonstrate to undergraduate students how GPS is used to monitor crustal movement at the Yellowstone Caldera
  2. To track and develop a record of ground deformation for the western region of the Caldera



Project Results

  • An ideal training ground for the application of GPS to active volcanic systems.
  • Puts advanced GPS instruments in the hands of undergraduate students.
  • Ground deformation results, in part, mirror the results of more comprehensive monitoring surveys.
  •  Deformation pattern is marked by ongoing uplift of the central region of caldera floor.
