A moderate tremor hits the border region of Tehran and Mazandaran provinces, triggering alerts but causing no immediate casualties.
A magnitude 4.6 earthquake shook northern Iran, striking the border region between Tehran and Mazandaran provinces at exactly 12:46 PM local time.
According to the Iranian Seismological Center, the epicenter of the tremor was located in the city of Pardis, situated within the Tehran Governorate bordering Mazandaran. The earthquake originated at a shallow depth of 10 kilometers beneath the earth's surface. The Fars News Agency reported that residents across several neighborhoods in the capital city of Tehran distinctly felt the ground shake.
While the earthquake caused sudden panic among locals near the epicenter, emergency services reported no immediate casualties or severe structural damage. Authorities in both Tehran and Mazandaran provinces immediately declared a state of high alert to respond to potential aftershocks or emergency developments.
Government operations, public services, and scheduled events in the capital and surrounding towns have not faced cancellations or disruptions, according to official statements. Disaster management teams continue to carry out field assessments to evaluate minor damages in rural areas nearest to the epicenter.
High Seismic Activity Zone
Iran lies on major seismic fault lines and remains one of the most earthquake-prone countries globally, experiencing hundreds of tremors annually.
A recent report published by the Tehran Times highlighted a sharp increase in seismic activity, noting that 247 earthquakes were registered across the country in just a single month spanning late March to April. That monthly figure included eight earthquakes measuring between magnitude 4 and 5, alongside 29 tremors ranging between magnitude 3 and 4.
Furthermore, data previously released by the University of Tehran indicated that Iran suffered approximately 2,380 earthquakes with magnitudes exceeding 2.5 over the preceding twelve-month period.
