Japan JMA Withdraws False 9.9 Quake Warning, Cites System Error

The Japan Meteorological Agency issued and then retracted a false 9.9 magnitude earthquake warning for the Kuril Islands within minutes, apologizing for public anxiety and transport disruptions. The incident suggests a system malfunction or human error in the early warning process, raising questions about the reliability of Japan's earthquake alert infrastructure. While no damage occurred, the false alarm underscores the potential for cascading societal and market impacts from erroneous disaster warnings.
