Dynamics of rock arches and towers

Jeff Moore, University of Utah

Utah’s rock arches and towers are dynamic geological features constantly vibrating in response to natural and anthropogenic energy sources. Measured vibrational characteristics are, in turn, controlled by rock mechanical properties, forming the basis for a non-invasion method of structural health monitoring. We measure the resonance properties and vibration response of prominent landforms in Utah, establishing baseline data and searching for trends that indicate reversible and irreversible change. Our results help inform questions of conservation and public safety for some of the world's most iconic geological features.
