Scope Subduction zone megathrust earthquakes and their accompanying tsunamis, such as the Tohoku-oki earthquake on March 11 in 2011, have caused severe damage in the past. Scientists have worked for decades to understand these devastating events, mostly based on seismic, tsunami and geodetic observations. In addition to these remote monitoring studies, the challenge of drilling into and directly sampling megathrust faults at seismogenic depth, analysis of drill core and downhole logs, experiments on sampled fault materials, and borehole measurements at depth has recently been taken up or being planned by the Integrated Ocean Drilling or International Ocean Discovery Program at Nankai Trough (Nankai Trough Seismogenic Zone Experiment), Japan Trench (Japan Trench Fast Drilling Project and Tracking Tsunamigenic Slips in the Japan Trench), offshore Costa Rica (Costa Rica Seismogenesis Project), Sunda Trench (Sumatra Seismogenic Zone Expedition), and at the Hikurangi margin (Unlocking the Secrets of Slow Slip). In this session, we welcome presentations based on such frontier studies, in addition to those based on seismic, tsunami and geodetic observations, numerical modeling, and analyses of fault rocks exhumed from seismogenic depth.
