A cluster of nine small earthquakes rattled the Pardis region east of Tehran overnight, as reported by Mehr news agency on Wednesday. The seismic activity has reignited concerns that the Iranian capital could be at risk of a major earthquake due to accumulated tectonic stress beneath and around the area.
Although small tremors are common, experiencing several in succession is rare. These shocks occurred near the Mosha fault—one of Iran’s most active seismic zones—and were felt throughout the eastern Tehran province.
State media noted that a 4.6 magnitude quake was recorded without causing casualties or damage. Seismologist Mehdi Zare highlighted the uncertainty of whether these tremors were a release of built-up energy or a precursor to stronger activity. Tehran’s dense population and fragile infrastructure exacerbate its risk, drawing sharp comparisons to the catastrophic 2003 Bam disaster.
