Abstract of the 242th meeting of CCEP

The 242th meeting of the Coordinating Committee for Earthquake Prediction (CCEP) was held at the Kanto Regional Survey Department of the GSI on February 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 "The 2024 Noto Peninsula Earthquake" was explained.
