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.
