Abstract of the 186th meeting of CCEP

The 186th meeting of the Coordinating Committee for Earthquake Prediction (CCEP) was held at the Kanto Regional Survey Department of the GSI on May 21, 2010. At first, Observation data and research results about seismic activities and crustal deformations in Japan were reported and discussed. Moreover, "Simulation of coupling and slip on the plate boundary" as intensive discussion subject were discussed. Finally, purport of next intensive discussion subject "Seismic activities" was explained.

Organization of CCEP of the 21st committee.
