Tehran Earthquake Early Warning System

An earthquake early warning system is designed to utilize the initial arrival of seismic phases, particularly the P wave, to swiftly detect earthquake parameters like location and magnitude. This valuable information is then utilized to generate timely warnings to critical infrastructure before the arrival of destructive waves like S waves and surface waves. Tehran, the capital of Iran, with a population of 10 million people, is situated in close proximity to several active faults capable of generating large-magnitude earthquakes, potentially exceeding a magnitude of 7.

In collaboration with Ferdowsi University of Mashhad, Mahan Geophysical Consulting played a significant role as a consultant in the development of an earthquake early warning system for Tehran. Our primary responsibility was to conduct a thorough scientific evaluation of the seismographic stations that were specifically designed and installed for this purpose and consultation on algorithm formulation and integration into the notification system. Through our assessment and evaluation, we ensured the effectiveness and reliability of stations and algorithms, enhancing their capabilities to accurately detect and analyze seismic activity.
