Abstract: The Geotechnical Extreme Events Reconnaissance (GEER) team performed post-earthquake reconnaissance in Taiwan following the 18 September 2022 M6.9 Chihshang, Taiwan earthquake. Our team investigated earthquake-induced landslides, surface fault rupture, and bridge damage using traditional reconnaissance techniques as well as unmanned aerial vehicles (UAVs) equipped with cameras and lidar. In this talk, I discuss the foregoing field observations, provide information about recorded ground motions, and then provide some preliminary physical interpretations. Finally, I discuss implications for the future of post-earthquake reconnaissance research.
