Abstract of the 203rd meeting of CCEP

 The 203rd meeting of the Coordinating Committee for Earthquake Prediction(CCEP) was held at the Kanto Regional Survey Department of the GSI on May 19, 2014. First, observation data and research results about seismic activities and crustal deformations in Japan were reported and discussed. Discussions were made under the intensive discussion subject."Wide-area and long-term deformation of the Japanese Islands". Finally, purport of next intensive discussion subject "Evaluation of predictability of earthquakes and crustal deformation" was explained.

• Deliberation about crusutal activity monitoring.

1.General crusutal activities.
（1）Seismic activities of Japan.
