Short summary
Short summary
We investigated the dynamic behavior of a rock arch to understand how fractures influence its stability. Using geophones, we measured its modes of vibration and used numerical modeling to replicate them. We found that higher-order resonance modes are the most sensitive to fractures, indicating their potential as early indicators of structural damage. Therefore, monitoring these higher-order modes could provide a more accurate tool to assess the structural integrity of natural rock landforms.
