Japan Retracts Erroneous Magnitude 9.9 Earthquake Alert After Russia Tremor
Japan's Meteorological Agency mistakenly issued a magnitude 9.9 earthquake alert following a 6.9 tremor near Russia's Kamchatka Peninsula on October 16. The warning, which predicted strong shaking across northern and central Japan, was retracted within eight to twelve minutes after officials identified the overestimation. No significant shaking or tsunami warnings occurred in Japan. The agency is investigating the cause of the error and has ruled out cyberattack involvement. A 9.9 quake would have been unprecedentedly powerful, releasing vastly more energy than the actual event.
