A 5.1-magnitude earthquake struck Iran’s Semnan province on Friday, June 20, 2025, with the epicenter located about 30 kilometers southwest of Semnan city at a depth of 10 kilometers. The tremors were felt across nearby regions, including Tehran, causing brief panic among residents.
The earthquake comes at a time of heightened tensions between Iran and Israel, drawing international attention to the region. Semnan is also known for its strategic space and missile facilities, making any seismic activity here particularly noteworthy.
However, Iranian authorities and international seismic agencies have confirmed that the earthquake was a natural tectonic event. The US Geological Survey (USGS) and other experts reported that the seismic patterns were consistent with a typical earthquake, ruling out any connection to nuclear testing or military operations.
Iran is one of the world’s most earthquake-prone countries, experiencing hundreds of tremors every year. The Semnan region itself has a history of significant seismic activity.
So far, there have been no reports of casualties or major damage. Local authorities remain on alert, and experts have urged the public to stay calm and not to spread rumors.
