Abstract of the 193rd meeting of CCEP

 The 193rd meeting of the Coordinating Committee for Earthquake Prediction (CCEP) was held at the Kanto Regional Survey Department of the GSI on November 18, 2011. At first, Observation data and research results about seismic activities and crustal deformations in Japan were reported and discussed. Moreover, "■The 2011 off the Pacific coast of Tohoku Earthquake." as intensive discussion subject were discussed. Finally, purport of next intensive discussion subject "Coupling and slip on the plate boundary;Around the Chishima trench." was explained.

• Deliberation about crusutal activity monitoring.

1.General crusutal activities.
