Currently, this investigation risks inspectors’ lives and limbs, costs hundreds of thousands of dollars, and still only crudely classifies buildings. PESES (Post-Earthquake Structural Evaluation System) is a proof-of-concept sensor network focused on estimating the level of structural damage that a building has experienced during ground shaking. Upon shaking, acceleration data is recorded and processed — and structural damage is calculated from this data. The system determines a damage rating (good, fair, poor) for the structure and visually presents this rating to the user, on both a website and an LED board. The team’s hope is that PESES, scaled to a web of buildings, could help communities recover more rapidly after earthquakes.
