Abstract of the 187th meeting of CCEP

The 187th meeting of the Coordinating Committee for Earthquake Prediction (CCEP) was held at the Kanto Regional Survey Department of the GSI on Aug. 20, 2010. At first, Observation data and research results about seismic activities and crustal deformations in Japan were reported and discussed. Moreover, "Seismic activities" as intensive discussion subject were discussed. Finally, purport of next intensive discussion subject "Plate Boundary" was explained.
