Japan braces for massive earthquake and tsunami
Japanese authorities have issued a warning about the high probability of a devastating earthquake along the Nankai Trough. Seismologists estimate that the magnitude of the expected quake could range from 8 to 9. The likelihood of the disaster occurring in the coming years is estimated at 80%.
Such a powerful earthquake would trigger a massive tsunami that could strike Japan’s eastern coastline. In some areas, wave heights may exceed 30 meters. Densely populated prefectures with critical infrastructure, industrial facilities, and residential zones are particularly at risk.
The scenario is based on seismic signals recorded between 2012 and 2013, which indicated growing instability in the Nankai Trough. Experts now say the current threat level is the highest in decades.
Japan’s government has already begun large-scale preparations. Over one million people — about 1% of the national population — may be evacuated. Emergency drills are underway, warning systems are being upgraded, and coastal defenses such as dams are being reinforced.
Preliminary estimates suggest the disaster could cause up to $1.81 trillion in economic damage, making it the most destructive natural event in modern Japanese history — even surpassing the 2011 earthquake and tsunami.
Seismologists urge the public to stay alert and familiarize themselves with evacuation routes and safe zones. Authorities emphasize that saving lives is the top priority, and preventive measures are already being implemented.
