Overview
- Residents across greater Tehran reported shaking shortly before midnight Tuesday local time after a magnitude 4.3 to 4.6 earthquake.
- The U.S. Geological Survey measured magnitude 4.3, while Iran’s state broadcaster IRIB put it at 4.6, reflecting routine early measurement differences.
- The epicenter was east of the city in the Pardis area near Damavand at roughly 10 kilometers depth, and tremors reached the suburb of Karaj about 40 kilometers west.
- Authorities and media reported no injuries or structural damage, and the USGS issued a green alert that signals low risk to life and property.
- USGS shaking estimates suggest up to about 22 million people may have felt light to moderate tremors, a common outcome for shallow quakes in Iran’s active seismic zone.
