چکیده مقاله
Earthquake Early Warning Systems EEWSS represent a critical advancement in mitigating seismic damage for urban areas This study reviews global EEWS implementations including Iran, the U S , Japan, and Mexico highlighting their methodologies and integration with public infrastructure Focusing on Tehran, Iran, situated atop active faults with a history of Mw 7 0 earthquakes, the development and deployment of the Tehran Earthquake Early Warning System TEEWS is detailed Beginning in 2010 as a regional/network based system, TEEWS utilizes accelerometer stations to detect P waves, estimate hypocenter location via probabilistic algorithms, using probabilistic location and site calibrated magnitude scaling relations During its 20 month trial, TEEWS provided up to 12 seconds of warning with median errors of 5 km location and 0 6 magnitude units Mw Challenges include lack of data for major earthquakes, in addition to establishing more stations The system demonstrates feasibility for automated risk mitigation in high threshold scenarios, though bedrock station placement and large earthquake simulations require further optimization
