Iran is facing a critical water crisis, exacerbated by prolonged drought and excessive groundwater extraction, which may trigger catastrophic earthquakes in major cities like Tehran, Isfahan, and Mashhad. Geology expert Mehdi Zare warns that these practices alter underground stress levels, potentially activating faults. Groundwater levels in Tehran are dropping significantly, leading to land subsidence and increasing seismic risks. Officials report alarming dam capacities and urge a 20% reduction in water usage as 19 provinces experience severe water stress. Without effective water management reforms, Iran risks transforming its drought crisis into a geological disaster. Sustainable practices are urgently needed.
