Nankai Trough: Japan’s Megaquake Warning

Japan has issued a warning about a possible megaquake in the Nankai Trough, a region prone to powerful seismic activity.

Understanding Megaquakes:

Also known as megathrust earthquakes, these are highly destructive quakes with a magnitude of 8 or higher.

About Nankai Trough:

1. A subduction zone where the Philippine Sea Plate is subducting beneath the Eurasian Plate in the Pacific Ocean.
2. Subduction zones are regions where two tectonic plates collide, with one sliding beneath the other.
3. Extends 900 km off Japan’s southwest Pacific coast, making it a high-risk zone for major seismic events.
