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

Welcome Beppu

The series of workshops initiated by CJK strategic program (2010-2013), meanwhile, similar program supported by Taiwan Earthquake Model (TEM) and NIED Japan (2012~ ) started and was fruitfully grown-up. New Zealand National Seismic Hazard Model (GNS Science) joined the latter in 2014.

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 of collaborated results will soon be issued on Seismological Research Letters.

Recently two destructive earthquakes occurred nearby the inland faults as the 2016 Meinong earthquake, Taiwan (M = 6.6, I cwb = 7, 117 fatalities) and 2016 Kumamoto earthquake, Japan (Mj = 6.5 and Mj = 7.3, I jma =7, 49 fatalities). Besides the regular topics, new themes raised such as

  1. A damaging earthquake on a blind fault
  2. Triggered fault displacement at large distances
  3. Mj 6.5 then Mj 7.3, (the tail that wagging the dog)
  4. Cumulated damage due to the two consequential earthquake
  5. Intense near-fault shaking and damages
  6. The fault was mapped and part of NSHA model
  7. Model aftershock sequence behavior

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