*****************************
1. 13:30-13:45
TITLE: Probing density structure of fault fracture zone with muon detector borehole in a borehole
AUTHOR: *Katsuya YAMAZAKI(Kanagawa University), Akimichi TAKETA
and Kentaro OMURA (NIED)
SUMMARY: We show current status and results of the muography detector
Which is installed in the borehole at Atotsugawa fault fracture zone.

2. 13:45-14:00
TITLE: OpenSWPC: An open-source integrated parallel simulation code for modeling
seismic wave propagation in 3D heterogeneous viscoelastic media
AUTHOR: *Takuto MAEDA, Shunsuke TAKEMURA (NIED) and Takashi FURUMURA
SUMMARY: We have developed an open-source software package, Open-source Seismic
Wave Propagation Code (OpenSWPC), for parallel numerical simulations of seismic
wave propagation in 3D and 2D (P-SV and SH) viscoelastic media based on
the finite difference method in local-to-regional scales.

3. 14:00-14:15
TITLE: A possible explanation for the coseismic electromagnetic signals
AUTHOR: *Hengxin REN・Yaochong SUN (Southern University of Science and Technology),
Makoto UYESHIMA, Qinghua HUANG (Peking University)
and Xiaofei CHEN (Southern University of Science and Technology)
SUMMARY: The combination of electrokinetic effect and scattering effect is
a possible explanation for the coseismic electromagnetic signals associated
with natural earthquakes.

4. 14:15-14:30
TITLE: Development of Historical Felt earthquakes Database Using Historical
Diaries
AUTHOR: Akihiko KATAGIRI, Rei MIZUNO (HI, UTokyo), and Akihito NISHIYAMA
