Abstract of the 244th meeting of CCEP

The 244th meeting of the Coordinating Committee for Earthquake Prediction (CCEP) was held at the Kanto Regional Survey Department of the GSI on August 29, 2024. And the meeting was onsite and online confference. Firstly, the nationwide monitoring data of the seismic activity was reported. Secondary, the CCEP members discussed the intensive discussion subject "30 years since the Great Hanshin-Awaji Earthquake, and 1 year from the Noto-Hanto Earthquake: Advances and challenges in Japan’s inland earthquake forecasting " was explained.
