Japan issues first megaquake advisory amid public confusion

Japan issued its first "megaquake advisory" following a magnitude 7.1 quake off Kyushu on August 8, 2024. The Japan Meteorological Agency estimates a 70-80% chance of a magnitude 8 or 9 quake in the next 30 years. The advisory has caused public confusion, leading to increased emergency supplies purchases and event cancellations, despite no abnormal seismic activity detected. Prime Minister Kishida is overseeing government response efforts.
