Peng, Zhigang
Dear all:
We would like to invite you to submit an abstract to our AGU session S016 - Mechanical State of Subducting Slabs and Physical Mechanisms of Deep Earthquakes: Integrating Seismological Observations, Laboratory Experiments, and Numerical Simulation (https://agu.confex.com/agu/fm22/prelim.cgi/Session/160468):
Subduction zones are the most tectonically active regions in Earth and exert a major force driving mantle dynamics. Slabs exhibit complex lithology and vary dramatically in terms of deformation history, thermal structure and volatile content. Deep earthquakes (depth > 70 km), which can be further categorized as intermediate-depth (70-350 km depth) and deep-focus (350-700 km), are a widespread feature of subduction zones. However, their causes and mechanisms remain a major scientific question. We invite contributions from observational studies, both field and laboratory, that address the properties and physics of deep earthquakes, together with theoretical and numerical modeling of the structure and mechanics of subducting slabs. Novel techniques to image deep slabs and deep earthquakes are especially welcome. Broader issues addressed may include constraints on deep seismogenesis, thermal structure and stress state in subducting slabs, and how to effectively combine the various approaches to better understand the puzzle of deep earthquakes.
As was done in year 2021, this meeting will be in a hybrid format for both in-person and online participation. The abstract deadline is August 3, 2022. Please submit your abstract at https://agu.confex.com/agu/fm22/prelim.cgi/Home/0
Thank you very much for your consideration.
