In August 2024, the Japan Meteorological Agency issued a special warning for the country's southern Pacific coast. It was feared that a very powerful earthquake would occur in the Nankai Trough area. This area is a long trench under the sea, where tectonic plates are under constant pressure.

If a major earthquake occurs in the Nankai Trough, how serious will the impact be?
