Overview
- The earthquake struck Tuesday around 16:27 local near Kumamoto with a shallow hypocenter about 10–16 kilometres deep and reached the highest Shindo intensity while magnitude estimates differed between agencies.
- An explosion inside the Aeon Mall in Kashima caused the second floor to partially collapse and police and broadcasters say roughly 20–30 people were reported missing there as crews search the rubble.
- Prime Minister Sanae Takaichi confirmed at least 13 deaths and officials report dozens of injured or hospitalized people as Self-Defense Forces, firefighters and police carry out large-scale rescue operations.
- The quake caused fires, multiple building and bridge failures, a derailed freight train and widespread service outages that left tens of thousands without electricity and forced suspension of rail services including the Shinkansen and temporary airport closures.
- Operators and regulators reported no immediate anomalies at nearby nuclear plants, the Japan Meteorological Agency warned of possible strong aftershocks that could worsen damage or hamper rescues, and the event renews concern in a region hit by deadly Kumamoto quakes in 2016.
