A recently announced research by the Institute of Geosciences and Minerals shows that the Trong Mai islet on Ha Long Bay is in danger of collapsing if the local authorities do not impose urgent protection measures.

Scientists from the institute made a detailed investigation, measurement and analysis combined with the use of satellite image analysis and building 3D models by using unmanned aerial vehicles to identify 40 blocks at risk of landslides on the islet. 

Researchers have proposed solutions such as using anchors to protect the sliding blocks, pumping cement to fill the cracks, and building load-bearing concrete walls to support the reinforcement of the cave walls among others. All these solutions must follow the principle of minimizing the impact, in parallel with conservation, without changing the landscape of Trong Mai islet.

The Department of Science-Technology Department of Quang Ninh Province has submitted solutions to preserve Trong Mai Islet to the local government.

Ha Long Bay in Quang Ninh Province was recognized twice by UNESCO as a World Natural Heritage site and voted one of the new Seven Wonders of the World. 

Ha Long Bay has a total area of about 1,553km2, with special values in geology, geomorphology and landscape. But modern geological and geodynamic processes have affected some mountainous areas in the bay, including Trong Mai Islet.

Trong Mai Islet (Fighting Cocks Islet) is considered a symbol of Ha Long Bay. It is located at the southwestern part of the bay, about 5 kilometers from Bai Chay tourist wharf. The islet is about 10 meters high above the sea level. It has the shape of a cock couple rising from the blue sea. 

These two huge cocks have stood by the other for thousands of years. As the story told by the locals, Trong Mai Islet represents faithfulness of love. The islet is most beautiful at dawn, when the sun sheds the first shine of a day and lights up the couple.
