Structural Health Monitoring of Rock Arches

Rock arches are dynamic geological features that perpetually vibrate in response to natural and anthropogenic energy sources. Measured vibrational characteristics are, in turn, controlled by internal rock properties, forming the basis for a new, non-invasion method of structural health monitoring. We measure the resonant frequencies and vibrational mode shapes of prominent arches in Utah, establishing baseline data and searching for permanent offsets or trends that may indicate internal damage. Our results can help inform questions of conservation and public safety for some of the world's most revered and iconic geological landforms.


Dr. Jeffrey Moore is an assistant professor of geology & geophysics at the University of Utah. His research interests focus on processes controlling rock slope failure, in-situ and remote monitoring techniques for state-of-health sensing and early-warning, and investigating the hazard and impacts of very large, infrequent landslides. Jeff spent five years studying rock slope instability hazard assessment and monitoring at ETH Zurich in Switzerland after completing his PhD in 2007 at the University of California, Berkeley. He is a native of Arizona and excited to be back working in the western US.
