On April 3, exchanging with Tien Phong, Mr. Tran Van Hoanh - Chairman of An Tien Commune People's Committee, My Duc District, Hanoi confirmed that in the district, there has been a phenomenon of land subsidence .

Local authorities dragged power lines to light up the subsidence area to protect the site and warn people.

By the evening of April 2, all households in the dangerous area were supported by the local authorities to evacuate to a safe place.

Representatives of the Department of Construction, Department of Natural Resources and Environment also sent officials to coordinate the initial preliminary inspection and evaluation."According to the mission, it is possible that under the stratum of the land there are many sand holes, this season the sprint leads to subsidence " - Mr. Hoanh shared.

According to Mr. Hoanh, in 2006, also in Hoa Lac village, about 100m away from the sinking position on April 2, there was a sinking pit, swallowing a whole bamboo. Subsequently, in 2010, when a household in Hoa Lac village conducted drilling wells, subsidence occurred.

In addition, in the field of the village, when people proceed to take water into production, there is a similar phenomenon. The water in the field drains the entire pit. For temporary processing, local authorities had to spread gravel and stones to level the fields to allow people to continue production. This shows that the cause of subsidence may be due to the weak geology of Hoa Lac village and many holes , deep underground circuits that have not been surveyed, causing incidents at any time.
