"Controlling the burn

In April 2010, President Gurbanguly Berdi­muha­medow recommended that measures be taken to limit the crater's influence on the develop­ment of other natural gas fields in the area.[9] In January 2022, Berdi­muha­medow announced plans to extinguish the crater, citing deleterious effects on local health, the environment, and the natural gas industry.[10][11] A commission was established to find the optimum technique.[6] Despite Berdi­muha­medow's intentions, the crater remains open and burning."
