A total of four people were trapped in two households, of whom three died in hospital despite emergency treatment, while the other is receiving medical attention and is in stable condition, according to the city's emergency management bureau. Five nearby residents who sought medical attention were examined at a hospital and later discharged. Search and rescue operations have ended.
