Japonia a emis o alertă de cutremur cu magnitudine de 9,9 grade, cel mai mare înregistrat vreodată în lume, dar pământul nu s-a zguduit

An emergency alert in Japan mistakenly announced a 9.9 magnitude earthquake, causing panic. The alert was retracted after eight minutes when authorities confirmed the actual quake was 6.9 magnitude off the Kamchatka Peninsula in Russia. The early warning system miscalculated the earthquake's magnitude and location, leading to widespread alarm and temporary disruptions in train services. Investigations are ongoing to determine the cause of the error, which was attributed to incorrect data processing and estimation methods. Japan's advanced monitoring systems aim to provide timely warnings, but inaccuracies can occur, especially with distant quakes.
