Japan Issues First Megaquake Advisory Amid Nankai Trough Risk

Japan has issued its first advisory on the heightened risks of a megaquake following a magnitude 7.1 quake near the Nankai Trough. A possible megaquake and tsunami could cause extensive damage and loss of life. Experts emphasize the importance of preparedness for what could be a historic natural disaster.

Japan issued its first-ever advisory on higher-than-usual risks of a megaquake, following a strong magnitude 7.1 quake on Thursday near the Nankai Trough. The advisory warns of potential catastrophic consequences from a possible Nankai Trough quake and tsunami, which could result in hundreds of thousands of fatalities and cause over a trillion dollars in damages.

According to Japan's Nankai Trough quake advisory panel, the chance of a larger earthquake following a magnitude 7 tremor is higher than usual. University of Tokyo professor Naoshi Hirata urges residents in vulnerable areas to review evacuation plans and remain vigilant.

Japan remains one of the most earthquake-prone nations, situated on the Pacific 'Ring of Fire.' The government estimates a 70-80% chance of a magnitude 8 to 9 quake striking the Nankai Trough in the next 30 years, potentially affecting millions and severely impacting the nation's infrastructure and economy.
