Abstract of the 206th meeting of CCEP

 The 206th meeting of the Coordinating Committee for Earthquake Prediction(CCEP) was held at the Kanto Regional Survey Department of the GSI on Feb 16, 2015. 　First the observation data, research results concerning the seismic activity, and the transformation of the hull in Japan were reported, and discussed. Discussions were made under the intensive discussion subject."Progress and problem from southern part of Hyogo Prefecture earthquake of active fault research for 20 years". Finally, purport of next intensive discussion subject "Monitor data and processing method of to grounds of forecast" was explained.

• Deliberation about crusutal activity monitoring.

1.General crusutal activities.
