The incident came to light on Saturday when residents noticed abnormal heat emanating from a specific spot on the ground. Subsequent digging revealed that heat was also coming from beneath the surface, raising concerns among locals.

A team from the Gosairhat Fire Service rushed to the scene after being informed and inspected the area. Firefighters initially tried to reduce the temperature by pouring water on the affected spot.

ABM Abul Bashar, station officer of Gosairhat Fire Service, said they observed unusual heat concentrated in a specific section of the ground.

“We have attempted to lower the temperature by applying water. However, it is not yet possible to determine the exact cause of the heat. The matter has been reported to the relevant authorities. If necessary, experts will be engaged to conduct further tests and identify the source,” he said.

Local residents speculated that the heat could be linked to underground gas, a chemical reaction or another geological factor, though no official explanation has yet been confirmed.

Authorities at the health complex and local administration are closely monitoring the situation and said necessary measures will be taken to identify the source of the heat and assess any potential risks.

The unusual incident has drawn crowds of curious onlookers to the health complex as residents await answers about the mysterious underground heat.
