The 2019 Japan-New Zealand-Taiwan
Seismic Hazard Workshop

Welcome to Lake Toya (Toyako), Hokkaido

We hereby invite you and your colleagues to attend the 2019 Seismic Hazard Assessment (SHA) meeting. The Group of SHA (G-SHA) workshop initiated by CJK strategic program after the 2008 Wenchuan earthquake, inherited by Taiwan Earthquake Model (TEM) and Japan (NIED) from 2012, as well as New Zealand (GNS Science) from 2014. The G-SHA workshop holds in every year since 2011 and turns to Japan this year. As consequent, Lake Toya (Toyako in Japanese) was selected. One of reasons is an occurrence of the devastative earthquake nearby, the 2018 Hokkaido Eastern Iburi Earthquake (Mj=6.7, fatality 42), with H=37km, much deep focus than usual inland earthquakes. Recently destructive earthquakes also occurred in Osaka (Mj=6.1), Japan, as well as in Hualien, 2018(Mw=6.4), 2019(Mw=6.1), Taiwan.

The island-arc settings of plate boundaries share many similarities and we all face similar challenges in modelling of seismic hazard. Through this ongoing series of workshops we aim to improve such topics as source characterization, ground motion simulation and prediction, subduction zone modelling and risk assessment. Some newer research topics will be focus on.

Colleagues from neighbor countries, and members of Global Earthquake Model Foundation (GEM) are very welcome to share ideas and join to our regional collaborations.
