Japan withdraws mistaken alert for a magnitude 9.9 earthquake

Japan's Meteorological Agency issued an earthquake early warning on Friday afternoon for a magnitude 9.9 quake and withdrew it about eight minutes later. The system overestimated the size of a magnitude 6.9 quake off Russia's Kamchatka Peninsula and placed it near the Kuril Islands. The strongest shaking in Japan was intensity 1, and no tsunami warning was issued. The agency says it is investigating and has no sign of a cyberattack.
