Huge subsided area after heavy rain in Da Nang

The hole is located right next to a sewer that dumps waste into the sea. It measures 2 metres in depth and 10 metres in width, and is the biggest sinkhole in Đà Nẵng till now. The cause of the incident is predicted to be due to strong water flows of residential areas running to the sea during the heavy rain. Da Nang Drainage and Wastewater Treatment Company mobilised vehicles and manpower to temporarily deal with the hole. My Khe Beach was recognised as 1 among the top 6 beaches of the planet. However there are 9 sewage release gates along the beach. The city is leading the way with a pilot program to collect rainwater thus controlling pollution.
