Publication of Questionnaire Survey Results on the 2024 Noto Peninsula Earthquake - Utilization of Earthquake Shaking, Earthquake Early Warning, and Tsunami Warnings

The Japan Meteorological Agency published questionnaire survey results on August 8, 2025 (Reiwa 7) regarding the January 1, 2024 earthquake in the Noto region of Ishikawa Prefecture (maximum seismic intensity 7). This survey was conducted to investigate the shaking conditions at the time, the acquisition and utilization status of earthquake early warnings and tsunami warnings, with the purpose of reviewing the JMA Seismic Intensity Scale explanatory table and promoting appropriate disaster prevention actions and various information. The survey results confirmed that the correspondence between seismic intensity and perceived shaking and damage conditions in each area was generally consistent with the JMA Seismic Intensity Scale explanatory table, and that many people took appropriate actions (protecting themselves from shaking, evacuating from tsunamis, etc.) when they saw or heard earthquake early warnings and tsunami warnings. Based on the survey results, the JMA will continue to endeavor to issue earthquake and tsunami information in a timely and accurate manner and promote awareness of safety knowledge.
