Rock arches are dynamic, sensitive and fragile landforms, and are constantly broadcasting their state health; we need only listen with the right set of tools to experience and begin to interpret this language. The iconic arches of Utah’s red rock desert are constantly in motion, trembling in resonance with the forces of the Earth. The natural frequencies of vibration are in turn controlled by geometry and material properties and combine to reveal a distinct vibrational fingerprint unique to every landform. Sped up and amplified, we can now experience these vibrations as sound, hearing the hidden voice of Utah’s red rock icons and forming the basis for a new, non-invasive method of structural health monitoring. Our team measures the ambient vibration of prominent rock arches and towers in Utah. Our results help inform questions of conservation and public safety for some of the world’s most revered geological landmarks, and provide a new way for visitors to engage with these dynamic rock formations aiming to inspire a spirit of respect and care. Lecture will be outside on the patio.
