Session ID#: 16656

Session Description:
As one of the most tectonically active regions in the world, South and East Asia has been struck by many destructive earthquakes in the past several decades. These seismic activities, both on-land and offshore, are the manifestation of the larger and longer-lasting regional tectonic processes, and highlight the need for a systematic understanding of these processes across various temporal and spatial scales. Furthermore, these short and long-term tectonic processes not only illuminate each other, but they also interact with atmospheric and earth surface processes to shape the Earth’s topography. In this session, we seek contributions from scientists who work on all aspects of the interactions between drivers of tectonism and surface responses to these forces. We encourage submissions from scientists in all related disciplines, including seismology, geodetic analysis, tectonic geomorphology, paleoseismology, paleotsunami studies, and modeling.
