A 5-meter deep crater opened up in Tehran’s Molavi Street as a result of land subsidence on Saturday at 9 am. The incident occurred in a narrow old alley where the subway station’s ventilation fans were placed underground, said Seyed Jalal Maleki, Tehran Fire Department spokesman. Stating that distressed neighborhoods are prone to land subsidence, he said, “Rusted and leaking water pipelines in the area are the main reasons for such instances,” IRNA reported.
