The sixth Workshop: 2016 Japan-New Zealand-Taiwan Seismic Hazard Assessment

Meeting report


Major participants in this meeting

The 6th International workshop was held in Beppu from October 31 to November 4, 2016.

Following the Wellington’s workshop in November 2015, this year workshop was hosted in Japan. The 64 scientists in total joined together, 28 participants from Taiwan, five from New Zealand, two from Colombia, one representative from Indonesia, Australia, Singapore and Italy were dispatched, and as well as 25 participants from Japan.

In the year 2016, several destructive inland earthquakes occurred in Meinong, Taiwan, Kumamoto, Japan, Accumoli, Italy, etc. The earthquakes themselves also brought scientists an opportunity to verify existed models of "National Seismic Hazard Map (NSHM)".

The 23 Oral presentations mainly related to "Probabilistic Seismic Hazard Assessment (PSHA)", such as source characterization, earthquake ground motion simulation and prediction, subduction zone modeling and risk assessment. The 32 poster concerning the seven research themes presented on the latest research results and issues.
Both of presentation ways attracted much attentions, especial for the young researchers.

"Seismological Research Letters" just released the special issues "Focus Section on the Joint Japan–Taiwan–New Zealand National Seismic Hazard Model Collaboration" and highlighted the 7 years collaborations between NIED and TEM, and 3 years with GNS, New Zealand.

Following the group discussions of the the Wellington’s workshop, we divided the four groups and discussed the direction of future researches, and the following group representatives made presentations on final summary meeting.

  • Group A (Matt Gerstenberger): PSHA and risk assessment related
  • Group B (Bill Fry): Earthquake observation and inversion, Earthquake source; characterization, Earthquake ground motion simulation and prediction
  • Group C (Yi-Rung Chuang): crustal deformation at the time of earthquake and after the earthquake, active fault
  • Group D (Kuo-Liang Wen): Subsurface Structure, Earthquake Engineering

After the meeting, about 53 people joined the field trip following the order of Beppu - Yufuin - Aso - Kumamoto. Firstly they deepened the knowledge of the geological setting of Kumamoto earthquakes and volcanos crossed Kyushu regions. Furthermore, they visited earthquake fault ruptured areas, Kawayo, Minami-Aso and Mashiki town, where suffered severe earthquake disasters, landslides and fatalities.
