Amir AghaKouchak, a professor of civil and environmental engineering and earth system sciences at the University of California, Irvine, told me in an interview that because land subsidence occurs in increments, the crisis is usually overlooked. “It lacks the dramatic visibility of acute disasters like earthquakes and floods, allowing authorities to underplay its risks,” says AghaKouchak. In Iran, “this invisibility is a key reason land subsidence remains on the sidelines in national disaster planning, despite its profound long-term consequences,” he adds.
