In the late 1960s, plate tectonics answered the question of why continents drift, in the process shedding light on the origins of earthquakes, volcanoes, mountain ranges, oceanic trenches, and landforms all around the world. Yet this was only one of many great overarching questions in tectonophysics, many of which still remain unsolved. Why do some faults creep while others stick and slip? To what extent can we see earthquakes coming before they happen? What is the state of stress in the Earth? What drives plate motions? What controls the strength of faults and plates? This session is an open discussion of great outstanding questions in tectonophysics and the disciplines it bridges, led by a panel of invited experts but open to all. Bring your own favorite (or least favorite/most troubling) questions to the table and join us for a lively discussion of the present and future of tectonophysics.
