| スコープ |
Knowledge on subduction zone earthquake phenomena has considerably increased in the last decades. Still, there are limits to comprehensively elucidate the earthquake mechanism in which phenomena differ by 10 orders of magnitude in space and time. One of the primary goals of IODP NanTroSEIZE was to reach and sample the seismogenic portion of plate boundary fault at ~5 km depth below sea floor offshore Kii Peninsula. Unfortunately, that objective has not been achieved due to difficulties in the drilling operations. Nonetheless, the NanTroSEIZE project has significantly advanced our understanding of the mechanics of earthquakes and faulting at the Nankai Trough and elsewhere. This session aims highlighting and synthesizing the scientific outcomes and technological advances from recent NanTroSEIZE expeditions that have advanced our understanding of the mechanics of earthquakes and slip behaviors along thrust plate boundary faults. We welcome, but not limited to, presentations from fields of ocean and land networks observation, seismogenic zone drilling, rock mechanical experiments, fracture process theory, etc. |
