Japan Meteorological Agency issues rare Nankai trough earthquake alert following Miyazaki quake

The Nankai Trough, a major seismic zone off Japan’s southeastern coast, is known for its potential to generate large-scale earthquakes, which could significantly impact the surrounding areas. The JMA’s decision to release this extra information underscores the heightened concern regarding seismic activity in the region. The alert aims to assess the likelihood of a powerful aftershock or megaquake in the Nankai Trough, a scenario that could pose substantial risks to both infrastructure and public safety.

The Japan Meteorological Agency (JMA) has issued Nankai Trough Earthquake Extra Information for the first time, following a significant earthquake that struck the Hyuga region in Miyazaki Prefecture on Thursday. This alert is designed to evaluate the potential risk of a subsequent major earthquake occurring in the Nankai Trough region.
