Tehran Earthquake Early Warning System

Earthquake early warning systems use the early onset of seismic phases (P wave) for rapid identification of earthquake parameters (location and magnitude) to generate warnings to infrastructure before the damaging waves arrive (S and surface waves). Iran's capital (Tehran) is home to 10 million people and is surrounded by several active faults capable of generating earthquakes with magnitudes up to 7. Mahan Geophysical Consulting acted as a consultant in this project, working with the Ferdowsi University of Mashhad, for scientific evaluation of the seismographic stations that were designed and installed for the purpose of an earthquake early warning system for the city of Tehran.
