convener:Tatsuya Kubota(National Research Institute for Earth Science and Disaster Resilience), Takashi Tonegawa(Research and Development center for Earthquake and Tsunami, Japan Agency for Marine-Earth Science and Technology), Yukihiro Nakatani(Nansei-Toko Observatory for Earthquakes and Volcanoes, Graduate School of Science and Engineering, Kagoshima University)

On-site poster schedule(2023/5/22 17:15-18:45)

Advances in ocean-bottom seismic observations with seismometers, hydrophones, and pressure gauges have provided us with the opportunity to study seismicity, subsurface structures, earthquake and tsunami generation, and wave phenomena in offshore areas. Permanent (cabled) observatories have enabled long-term monitoring for these targets, and deployments of dense temporary arrays or fiber optic technologies have open techniques for offshore seismic datasetsed up the possibility of higher-resolution researches. Also, such growths of ocean seismology have invoked the community to create data processing and analyzing techniques. The purpose of this session is to share recent advances in the ocean seismology, such as seismicity, seismic velocity structure deduced from active and passive approaches, progresses in the development of seafloor instrumentation, processing and analyzing techniques for offshore seismic datasets, findings of the generation mechanisms of subseafloor earthquakes and tsunamis, observation of the seafloor strong motion, characterization of ambient noise and interpretation of its sources, propagation processes of various waves in the atmosphere, ocean, and solid Earth recorded by ocean instruments, and all relevant topics. We welcome presentations by early-career researchers and students who wish to try the presentation in an international session.
