Seismologists have recorded a magnitude 4.7 earthquake in Iran, with the epicentre located 55 km NW of Shahrak-e Kūlūrī, Iran. The event occurred at 15:01 UTC on Monday, August 10, 2026 and originated at a depth of 10.0 km.
Seismic Context for Iran
Iran sits on the Iranian Plateau, caught between the Arabian Plate pushing northward and the Eurasian Plate. This compression is accommodated along a complex network of reverse and strike-slip faults crossing the entire country.
Iran has experienced many catastrophic earthquakes, including the 2003 Bam earthquake (M6.6, ~26,000 deaths) — largely caused by collapse of traditional mud-brick architecture — and the 2012 East Azerbaijan earthquakes. Seismicity is widespread, with few regions of the country considered truly low-risk.
About This Event
At a focal depth of 10.0 km, this is classified as a shallow earthquake (0–70 km). Shallow events are typically the most damaging: the seismic energy has less distance to travel before reaching the surface, resulting in stronger and more abrupt ground shaking at the epicentre.
In terms of felt effects, a magnitude 4.7 earthquake is typically felt strongly by everyone; minor to moderate damage possible in vulnerable buildings. Moderate earthquakes are felt by virtually everyone near the epicentre. Strong shaking lasting 10–30 seconds can topple unsecured items, crack plaster, and cause poorly anchored objects to fall. Aftershocks are common following moderate events.
Understanding the Magnitude Scale
Earthquake magnitude is measured on a logarithmic scale — meaning each whole-number increase corresponds to roughly 32 times more energy released and approximately 10 times greater ground motion amplitude. A magnitude 4.7 event therefore releases significantly more energy than its number alone might suggest to the casual observer.
A magnitude 4.7 earthquake releases approximately roughly 500 tonnes of TNT of energy. For comparison, this exceeds the energy released by most conventional explosive events and is sufficient to shift tectonic stress in measurable ways across a wide region.
Significant damage can occur to vulnerable structures — particularly unreinforced masonry, old adobe buildings, and poorly maintained older construction. Well-engineered modern buildings are designed to withstand this level of shaking with minimal structural impact, though contents may shift and non-structural elements (ceilings, partitions) can be damaged.
What to Do After an Earthquake
Agree on an out-of-area contact that family members can reach if local communications are disrupted. Identify two meeting points: one near your home and one further away. Practise earthquake drills, especially with children and elderly household members.
After an earthquake, expect aftershocks. Check yourself and others for injuries. Inspect your surroundings for hazards before moving — broken glass, gas leaks (smell), downed power lines, and structural damage. If you suspect a gas leak, open windows and evacuate without using electrical switches or open flames.
Staying Informed
The Institute of Geophysics, University of Tehran and the Building and Housing Research Center (BHRC) play key roles in earthquake monitoring and building code development.

Community Felt Reports
If you felt this earthquake, your experience contributes to an important scientific dataset. The USGS "Did You Feel It?" (DYFI) system and QuakeWatch's own community reports platform collect first-hand accounts of shaking intensity from people across the affected region. These reports — describing where people were, what they felt, and what moved or was damaged — help seismologists map shaking intensity across an area much larger than any single seismograph can cover.
