A new parameter characterizing transverse isotropy





Spatiotemporal evolution of the 2013-2014 Boso slow slip event

* Jun'ichi FUKUDA, Aitaro KATO (Nagoya University), Kazushige OBARA,

Satoshi MIURA (Tohoku University), Teruyuki KATO


We discuss the spatiotemporal evolution of a slow slip event and

associated earthquake swarm activity near Boso Peninsula from

December 2013 to January 2014.




grain size segregation in earthquake faults and its implication

Development of numerical simulation for accurate muographic imaging

of geoscientific targets: current status and future prospects

* Ryuichi NISHIYAMA, Akimichi TAKETA, Seigo MIYAMOTO


We have developed a method for numerical simulation to improve

the accuracy of the density imaging with cosmic-ray muon radiography.

In this talk, we describe our motivation, current status and future

prospects including publication of the source codes.
