Nine Tremors Near Tehran Raise Quake Fears

A series of nine small earthquakes struck the Pardis area east of Tehran overnight, renewing fears among experts and residents that the Iranian capital could face a major seismic disaster, according to multiple reports.

The repeated activity has revived concerns about accumulated tectonic pressure beneath and around the capital, which lies close to several active fault lines. The tremors were felt in an area near the Mosha fault, one of Iran’s most active seismic zones, as reported by TimesLIVE, Reuters, and Al Jazeera.

The earthquakes were recorded over a single night in eastern Tehran province, with state media reporting that one reached a magnitude of 4.6. The mild seismic activity did not cause casualties or material damage. Semi-official Mehr news agency cited seismologist Mehdi Zare, who stated it was unclear whether the tremors represented a release of built-up seismic energy or were warning signs of stronger future activity along the fault system near Tehran.

Zare warned that Tehran’s vulnerability is amplified not only by active fault lines but also by dense urban development, population concentration, and limited preparedness. He noted that even relatively small earthquakes can cause disruption in the capital due to fragile infrastructure and congestion, complicating emergency responses. Tehran, a metropolitan area of more than 14 million people, lies near major active faults including the North Tehran, Mosha, and Rey fault systems.
