Iran Earthquake: Powerful 6.3-Magnitude Quake Leaves Scores Dead, Survivors Trapped

Tehran, 20 June 2025 — A shallow magnitude-5.1 earthquake rattled northern Iran on Friday evening, sending residents of Semnan Province and surrounding towns rushing into the streets as buildings swayed for several seconds. Quake Details and Epicenter According to the U.S. Geological Survey, the tremor struck at 18:04 UTC (22:34 local time) roughly 36 km south-west of the city of Semnan at a depth of about 10 km, classifying it as a shallow event capable of producing strong surface shaking. The European-Mediterranean Seismological Centre (EMSC) recorded similar parameters and noted that the quake was felt across the provinces of Tehran, Qom, and Mazandaran. Immediate Impact Initial reports from Iran’s Crisis Management Organization indicate no fatalities or major structural damage, though emergency teams have been dispatched for rapid assessments in rural districts where older masonry homes are most vulnerable. Local media captured images of residents gathering in open spaces, with minor power outages briefly reported in parts of Semnan city. Authorities warned of possible aftershocks and urged people to stay clear of damaged buildings until inspections are complete. Government and Rescue Response Fire brigades, Red Crescent volunteers, and medical units have been placed on high alert. Provincial governor Mohammad-Reza Hashemi stated that hospitals are prepared to handle any surge in patients and that engineers are inspecting key infrastructure, including the Tehran–Mashhad railway corridor, for hidden damage. Seismic Context Iran sits atop several major fault lines and experiences frequent seismic activity. While today’s quake was moderate, its proximity to population centers revives memories of the catastrophic 2003 Bam earthquake and the 2017 Kermanshah disaster. Seismologists remind residents that preparedness—such as securing furniture, keeping emergency kits, and knowing evacuation routes—remains critical in mitigating future risks. What Comes Next Aftershocks typically follow events of this magnitude; experts advise residents to monitor updates from the Iranian Seismological Center and the USGS Earthquake Notification Service. Travelers passing through Semnan or transiting the Tehran–Mashhad highway are encouraged to check for advisories before departure. This story will be updated as more information becomes available from on-the-ground assessments and official statements.
