报告摘要:
About 75% of global earthquakes and volcanoes are rooted in subduction zones. Subducting plates, or slabs, bring materials from the Earth’s surface to the deep Earth and thus play an important role in Earth’s interior material distribution, recycling, and evolution. Recent seismic observations crossing shorelines greatly advanced our understanding of subduction zone earthquakes, arc volcanoes, and the Earth’s deep material cycle. In this talk, I will first present some new methodology developments utilizing amphibious seismic array data in the Tonga subduction zone, including machine-learning techniques in detecting deep earthquakes and transdimensional MCMC tomography. Then, I will present our latest studies on slab dehydration and mantle wedge melting in the Alaska subduction zone. In sum, subduction zones, particularly the offshore part, are uncharted waters in seismology. New data and emerging methods and technologies will lead us to new discoveries and directions in subduction zone sciences.
