Predicting Japan’s Nankai Trough megaquake

Japan experienced a magnitude 7.1 earthquake, followed by a warning of a potential major earthquake. The Nankai Trough, prone to megathrust earthquakes, poses a significant risk with a 70-80% chance of a magnitude 8 or 9 quake in the next 30 years. Despite concerns, predicting earthquakes remains challenging. The recent alert issued by Japan Meteorological Agency prompted preparation but did not mandate evacuation. While some question the necessity of the alert, it did raise awareness and led to safety evaluations along the coast. Potentially affecting trillions in damages and causing mass casualties, the “Big One” remains a looming threat for Japan. With Japan’s history of seismic activity, vigilance and preparedness are crucial. Ensuring emergency supplies and evacuation plans are in place is recommended by experts. While the threat of a major earthquake persists, Japan must remain resilient and proactive in the face of impending natural disasters.
