Abstract

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
