Abstract of the 216th meeting of CCEP

  The 216th meeting of the Coordinating Committee for Earthquake Prediction (CCEP) was held at the Kanto Regional Survey Department of the GSI on Aug 21, 2017. Firstly, nationwide monitoring data of the seismic activity and the crustal deformaitons were reported. Secondary, the CCEP members discussed the intensive discussion subject "Earthquake centered just under the capital". Finally, the purport of next intensive discussion subject "Trial of experimental earthquake forecast Part 4" was explained.

• Deliberation about crusutal activity monitoring.

1.General crusutal activities

     p3 (JMA)
（2）Activity of shallow very low frequency earthquakes around Japan.
     p4 (NIED)
（3）Strain changes in the Japanese Islands.
     p5 (GSI)

1.2 The coupling state and change on the plate boundary
