The head of Iran's Earthquake Prediction Center warned that groundwater levels in several plains east of Tehran have dropped by more than 60 meters. He said decades of drought and over-extraction could alter stress balances on geological faults and change the earthquake risk profile for the Tehran area.
The head of Iran's Earthquake Prediction Center issued a warning Monday evening about significant groundwater depletion in plains east of Tehran, stating that levels have dropped by more than 60 meters. He said decades of drought and over-extraction of groundwater could affect the balance of forces in geological faults in the area, potentially altering the stress state and increasing seismic risk for the Tehran region. The warning follows a series of recent seismic events near the capital that have drawn attention to the region's geological stability, though the center chief's assessment is a separate analysis of long-term environmental factors rather than a short-term forecast.
