Investigating the Largest Landslides on Earth
Abstract: Volcanoes produce the largest mass movement events on earth, capable of containing 10’s of cubic kilometers of material and traveling 100’s of kilometers away from their source. Once considered rare, these catastrophic events are now recognized to be a common process in the evolution of volcanoes. Why are volcanic landslides larger and typically more devastating than their non-volcanic counterparts? How do complicated relationships between hydrothermal systems, magmatism, glaciation, and tectonics uniquely affect the likelihood and scale of landslide hazards? And how do we deal with complex and uncertain hazards that cannot be solved with modern engineering?
This talk will touch on several novel, integrated approaches for understanding the conditions and consequences of volcanic landslides, including: (1) New trends and relationships in volcanic materials from high temperature, high pressure, and dynamic loading experiments; (2) Advanced interferometric synthetic aperture radar techniques to create operational mitigation tools, and; (3) 3D engineering geology maps created from aero-magnetic and hyperspectral remote sensing.
