Session
The 2011 Tohoku earthquake and earthquake cycle

For the 2011 Tohoku earthquake, various models for co-seismic and post-seismic slip distributions, tsunami sources, and source processes have been presented. In this session, we aim to share our results on the Tohoku earthquake and to understand what is going on during megathrust-zone earthquakes and inter seismic periods.
