Science, Hazards and Planning in Subduction Zone Regions I

Date: 4/24/2019

Time: 4:15 PM to 5:30 PM

Room: Cascade II

Subduction zones host the Earth’s largest faults and many of its active volcanoes. Subduction systems also play a central role in the formation and accretion of continental crust and are responsible for recycling oceanic crust and volatiles into the mantle. This session explores the latest multidisciplinary scientific advances in subduction zones around the world, including their mechanics, structure, evolution and dynamics from the trench to the backarc. We welcome studies that explore such topics as seismicity, tremor and deformation transients, including the slip behavior of faults and tsunami genesis, as well as studies that explore the geologic signatures of these processes. Below the arc, studies may explore volatile and magma migration, mantle wedge dynamics and melt production in the lower crust.
The dynamic processes inherent to subduction zones also challenge society’s prosperity given the potential for natural disasters with broad regional impacts. These natural disasters are often compound events, as in the case where large earthquakes can trigger both landslides and tsunamis. The successful mitigation of these natural hazards requires a thorough scientific understanding of the underlying processes. Therefore, we also welcome studies that explore the recurrence, probability, potential impacts and mitigation strategies of these natural hazards.
