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 mattersJapan
