A magnitude 4.3 earthquake struck near Tehran, Iran, according to the US Geological Survey. Iranian state media reported a slightly higher magnitude of 4.6.
TEHRAN, Iran — May 12, 2026
A moderate earthquake shook areas near Tehran, Iran, on May 12, 2026, with conflicting reports on its exact magnitude.
The United States Geological Survey (USGS) recorded the earthquake at a magnitude of 4.3, while Iran’s state broadcaster IRIB reported it as 4.6. The discrepancy highlights differences in measurement methodologies between international and local seismic agencies.
The USGS, a globally recognized authority on earthquake monitoring, typically provides rapid assessments of seismic events worldwide. Its data is widely cited by international media and disaster response organizations. Meanwhile, IRIB’s higher figure may reflect adjustments based on regional seismic monitoring networks.
The quake’s epicenter was near the Bezirk Pardis area, close to Tehran, though no immediate reports of significant damage or casualties were available. Earthquakes of this magnitude are often felt strongly in urban areas but rarely cause widespread destruction.
Tehran, a densely populated metropolis, sits on several active fault lines, making it particularly vulnerable to seismic activity. The region has experienced devastating earthquakes in the past, raising concerns about preparedness for larger tremors. Authorities have yet to issue official statements regarding structural assessments or emergency response measures.
