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

Marine seismic, tsunami and geodetic observations have difficulties compared to land observations. Therefore, few large-scale observation networks had been deployed before the occurrence of the 2011 Tohoku-oki earthquake. As we have rapid progress for technological development, large-scale observation systems were installed after the 2011 Tohoku-oki earthquake and the data from such new marine networks are available at the present. Using the data from up-to-date large-scale seafloor cable observation system and GNSS-A geodetic observation system, we obtained new scientific results such as detailed seismic activities including slow earthquakes and precise coupling between oceanic plate and landward plate. In addition, development of observation system using new technology, for example optical fiber sensing is vigorously progressed. Moreover, we have a plan to install the state-of-the-art seafloor cabled observation system and real-time continuous seafloor borehole geodetic observation system in the western source region of the Nankai trough earthquakes. This session has objective to discuss marine observational researches from views of wide solid-earth sciences such as new marine observation technologies and observation systems, including innovative results from data obtained by up-to-date marine observation system.
