Historical Context
Ring of Fire:
Japan is located in the seismically active “Ring of Fire,” known for frequent earthquakes and volcanic activity.
Nankai Trough:
A significant seismic zone in the southwest Pacific coast where the Philippine Sea Plate subducts under the Eurasian Plate.
Historically causes megaquakes every 100–150 years.
In August 2024, Japan issued an advisory on the heightened risk of a Nankai Trough megaquake following a magnitude 7.1 earthquake.
The government predicts a 70–80% chance of a magnitude 8–9 earthquake occurring along this trough in the next 30 years.
