Abstract of the 211th meeting of CCEP

 The 211th meeting of the Coordinating Committee for Earthquake Prediction(CCEP) was held at the Kanto Regional Survey Department of the GSI on May 18, 2016. 　First of all, nationwide monitoring data of the seismic activity and the crustal deformation were reported. After that, we discussed 2016 Kumamoto earthquakes. 　Please see to the overviews below.
