Japan False 9.9-Magnitude Earthquake Alert Retracted

Japanese authorities mistakenly issued a 9.9-magnitude earthquake warning, the strongest ever recorded, which was retracted after approximately eight minutes. The error was attributed to an overestimation of a 6.9-magnitude quake in the Kuril Islands, not a real seismic event. No damage or casualties have been reported, but the incident raises concerns about the reliability of Japan's early-warning system and public trust.
