Japan’s meteorological agency mistakenly issued a nationwide earthquake alert warning of a magnitude 9.9 quake, triggering widespread emergency alarms on mobile phones across the country. The agency quickly retracted the alert, explaining it was a false alarm. Investigations revealed the initial alert stemmed from data related to a 6.9-magnitude earthquake that actually occurred near Russia’s Kamchatka Peninsula. This quake was recorded at a depth of 160 kilometers (100 miles). The error caused significant alarm among the Japanese population, prompting questions about the accuracy of the country’s early warning systems. Officials have pledged to investigate the cause of the malfunction and prevent similar incidents in the future. The impact zone of the actual earthquake was far from Japan, posing no tsunami threat to the nation.
