Japan Mistakenly Issues Warning for Strongest Ever Earthquake
The Japan Meteorological Agency mistakenly issued an emergency alert for a magnitude 9.9 earthquake at approximately 12:36 p.m. Friday. The warning forecasted strong shaking across much of the country, but officials withdrew the alert at 12:48 p.m. after determining the threat was incorrect. The actual seismic event was a magnitude 6.9 earthquake that struck near Russia's Kamchatka Peninsula. While the false alert suggested the strongest earthquake ever recorded, the actual tremor was hardly felt in Japan. Authorities confirmed the error was not caused by a cyberattack.

Japan Withdraws False Warning for Magnitude 9.9 Earthquake
The Japan Meteorological Agency mistakenly issued an emergency alert for a magnitude 9.9 earthquake at approximately 12:36 p.m. Friday. The warning forecasted strong shaking across much of the country, but officials withdrew the alert at 12:48 p.m. after determining the threat was incorrect. The actual seismic event was a magnitude 6.9 earthquake that struck near Russia's Kamchatka Peninsula. While the false alert suggested the strongest earthquake ever recorded, the actual tremor was hardly felt in Japan. Authorities confirmed the error was not caused by a cyberattack.
Why it matters
Japan maintains a highly sensitive early warning system to protect its population from frequent seismic activity. A magnitude 9.9 event would be unprecedented in recorded history. The timing of the false alert coincided with a real but less severe earthquake in Russia.
