Workshop
New perspective on subducting seamounts and slow earthquakes
through drilling and monitoring
Objective
The IODP proposal for Hyuga-Nada drilling to understand the effect of seamount subduction on slow earthquakes were sent to Chikyu IODP Board (CIB) with an excellent rating. The lead proponents (Rie Nakata, Masataka Kinoshita, Yoshitaka Hashimoto and Yohei Hamada) are organizing this workshop and aim to discuss what/how scientific drilling and borehole observatories, integrating with seismological/geophysical observations, can provide the clue for understanding the relationship between subducting seamounts and slow earthquakes .We do not limit our discussions to Hyuga-Nada. We want to be broad and include up-to-date achievements in other significant subduction zones marked by the subduction seamounts. We hope this workshop will be a good oppotunity to make a scientific community for the subject in the future IODP. This workshop is also co-organized by A01 and A02 groups in JSPS KAKENHI, Grant-in-Aid for Transformative Research Areas (A) "Science of Slow-to-Fast earthquakes".
