Abstract of the 214th meeting of CCEP

 The 214th meeting of the Coordinating Committee for Earthquake Prediction(CCEP) was held at the Kanto Regional Survey Department of the GSI on February 20th, 2017. 　First of all, nationwide monitoring data of the seismic activity and the crustal deformations were reported. After that, we discussed about intensive discussion subject "Trial of experimental earthquake forecast Part 3".　Please see to the overviews below.
