Explore a comprehensive geophysical analysis of the catastrophic 2014 Oso landslide disaster in this 22-minute conference talk from the AGU Fall Meeting. Delve into the unique characteristics of this high-mobility landslide, including its gradual onset, abrupt acceleration, and exceptional runout distance. Examine seismic data interpretations, eyewitness accounts, and numerical simulations to understand the complex factors contributing to the event's devastating impact. Investigate the role of exceptional precipitation, soil properties, and liquefaction in the landslide's behavior. Compare the Oso event to other landslides and discuss its implications for landslide hazard assessment. Gain insights into the latest research on landslide mobility and the physical processes that can lead to catastrophic outcomes.
