We are pleased to announce that we will hold a workshop of “slow earthquakes” on September 8th-10th at the Uji campus, Kyoto University. In this workshop, we focus on understanding of slow earthquake itself, and relationships between slow earthquakes and megathrust event, such as a future Nankai-Tonankai earthquake. We also focus on seismic and geodetic monitoring of slow earthquake at sea-bottom as well as landward.
Date: September 8th – 10th
Venue: Kihada hall, Uji campus, Kyoto University

Conveners: Yoshihiro Ito, Hitoshi Hirose, Kazushige Obara
This workshop is supported by Joint Usage/Research Center Programs of DPRI Kyoto University and ERI The University of Tokyo, J-DESC feasibility study, JSPS KAKENHI Specially Promoted Research and Scientific Research (A).
