Abstract of the 217th meeting of CCEP

  The 217th meeting of the Coordinating Committee for Earthquake Prediction (CCEP) was held at the Kanto Regional Survey Department of the GSI on Nov 22, 2017. Firstly, nationwide monitoring data of the seismic activity and the crustal deformaitons were reported. Secondary, the CCEP members discussed the intensive discussion subject "Trial of experimental earthquake forecast Part 4". Finally, the purport of next intensive discussion subject "Tasks seen through 2016 Kumamoto earthquakes" was explained.
