Iran is one of the most seismically active countries in the world, and understanding this risk is the first step toward preparedness.
Iran sits on the Alpine-Himalayan seismic belt, the same belt that makes cities like Istanbul and Tokyo earthquake-prone. Hundreds of active and inactive faults are scattered across the country, making earthquakes a relatively frequent occurrence. Over the past century, earthquakes such as Buin-Zahra (1962), Tabas (1978), Rudbar-Manjil (1990), Bam (2003), and Ezgeleh-Sarpol-e Zahab (2017) have been among the most destructive events in Iran’s earthquake history.
Tehran lies close to several active faults, including the North Tehran fault, the Mosha (Fasham) fault, and the Rey fault. According to researchers at the International Institute of Earthquake Engineering and Seismology, these faults have historically produced earthquakes above magnitude 7 — which is why real-time earthquake monitoring in Tehran matters so much for residents of this metropolis.
Iran’s National Seismological Center and the Institute of Geophysics at the University of Tehran operate a network of seismograph stations across the country, recording and processing ground vibrations to determine each earthquake’s magnitude, depth, and precise location as quickly as possible. Larzeh-bin delivers this official data to you in a simple, easy-to-understand format.
A seismograph (seismometer) is an instrument that records even the smallest vibrations of the earth as an oscillating line — the same line simulated live at the top of this page. The greater the amplitude of the oscillation, the higher the earthquake’s magnitude. Combining data from hundreds of seismographs across Iran makes it possible to precisely locate the epicenter of every earthquake.
Install it on your phone or use it straight from your browser — the data is identical and real-time in both versions.
The latest events recorded by the country’s seismograph stations, along with exact time, magnitude, and location, are displayed live in the Larzeh-bin app and web version.
Iran lies on the Alpine-Himalayan seismic belt and is crossed by numerous active faults. Tehran itself sits near the North Tehran, Mosha, and Rey faults, among the country’s most significant active faults.
A seismograph records the movement and vibration of the earth’s crust as an oscillating line. The country’s network of seismograph stations processes this data to determine each earthquake’s magnitude, depth, and location.
Iran’s National Seismological Center is responsible for recording, processing, and officially announcing the details of earthquakes across Iran through its network of seismograph stations.
