The 2015 NIED-TEM workshop of Seismic Hazard Assessment
The purpose of this working group discussion is to strengthen the interaction
between NIED and TEM and ultimately improve our capability on the earthquake
hazard assessment of these two countries. We plan to organize 5 working groups inthis discussion; they are (1) active fault parameters, (2) velocity structure, (3) scenario
earthquake, (4) GMPE, and (5) earthquake hazard. The specific questions and thecorresponding TEM and NIED members for each group are listed as follows:(1) Active fault parameters
J. Bruce H. Shyu, Jian-Cheng Lee, Kuo-En Ching, Ray Chuang, Yuan-Hsi Lee,Ling-Ho Chung, and Ruey-Juin Rau, 粟田泰夫(Yasuo Awata), 吾妻崇(TakashiAzuma), 武田哲也(Tetsuya Takeda)(a) How to deal with fault segmentation and connection (e.g., the 1935
Taichung-Hsinchu event ruptured two adjacent fault segments)? Do we follow
UCERF3 and propose ‘Plausible Rupture Criteria’?
(b) How to deal with Mu (the maximum magnitude of the fault) for active fault
sources? The magnitude estimated from fault source is smaller than thereported magnitude of the historical events (e.g., 1906 Meishan).
(c) How to determine the fault slip rate without trenching data? How to deal with
their uncertainty?
(d) How to determine the slip rate deficit properly on a creeping fault?
(e) How to estimate the earthquake hazard for a creeping fault?

(2) Velocity structure
Kuo-Liang Wen and Chun-Te Chen, 先名重樹(Shigeki Senna), 木村克己
(Katsumi Kimura), 松山尚典(Hisanori Matsuyama)(a) How to obtain the shallow and deep structure? What is the Suggested
resolution? What information and data we need so as to construct the 3D
velocity model?
(b) Can we combine shallow and deep structure with Tomography model?
(c) We have about 128 microtremor array measurements (interval 10~20km) and3917 microtremor single station measurements (interval 1~2km) in Taiwan.
(d) Is these data enough for mapping the subsurface structure?
(e) How to plan appropriate fieldwork survey and how about the budget you needfor the area like Taiwan? What is the current situation in Japan?
(f) How to do model modification compared to observed waveform data withnumerical modeling?

The 2015 NIED-TEM workshop of Seismic Hazard Assessment(3) Scenario earthquake waveform simulation
Yi-Wen Liao and Yin-Tung Yen, 前田宜浩(Takahiro Maeda), 青井真(ShinAoi), 岩城麻子(Asako Iwaki)(a) How to incorporate shallow structure into scenario earthquake simulation?
(b) How to simulate high frequency?
(c) How to create more reliable source models for scenario earthquake simulation(d) How to determine suitable match filter in broadband simulation(e) How to quantify sensitivity of velocity structure in various frequency band ofground motion simulation(4) GMPE
Po-Shen Lin, 森 川 信 之 (Nobuyuki Morikawa), 藤 原 広 行 (HiroyukiFujiwara)(a) How to incorporate shallow structure (e.g., for response spectra)?
(b) How to minimize deviation?
(c) GMPEs in intensity?

(5) Earthquake hazard
Yating Lee, Yu-Ju Wang, Chung-Han Chan, and Kuo-Fong Ma, 井元政二郎(Masajiro Imoto), 森川信之, 河合伸一(Shinichi Kawai), 郝憲生(Ken XS.
Hao), 藤原広行(a) Is fault source independent of background area source? How to deal with Mu(the maximum magnitude of the area seismicity) for a- and b-values of the areasources with and without faults? TEM makes the M>Mu to be fault related.
(b) Use logic tree to implement area source and active fault source independently?
Can area source parameters be modeled by earthquake catalog, whereas active
fault ones by geological, geomorphological and geodetic evidence? How toevaluate the potential maximum magnitude of background area source? How todeal with fault segmentation for PSHA? How to deal with the slip rate for one
segment or two?
(c) Hazard map in intensity? GMPE in intensity? Through a relation between
PGA/PGV/SA and intensity?
(d) How to deal with unexpected extreme events (with extra-large magnitudes)?
(e) How to determine the b-values in characteristic earthquake model for faults
which are spanned two or more areas?
(f) Should time-dependency be implemented? And how to implement it?
Not a well-developed approach.

The 2015 NIED-TEM workshop of Seismic Hazard Assessment
Long-term (e.g., BPT, Lognormal etc.), how to treat non-characteristic events?
How to determine the elapse time for those faults without
historical/paleo-seismic (trenching data) rupture records?
Short-term (e.g., ETAS, Coulomb etc.)
Should time-dependency be magnitude-dependent? And how to quantify
magnitude-dependent term?
