Major and Strong Earthquake Sequences and the inefficiency of Seismic Hazard Zoning Map: Iran ۲۰۱۷ Mw۷.۴, Turkiye ۲۰۲۳ Mw۷.۸ and Myanmar ۲۰۲۵, Mw۷.۷

Seismic hazard zoning maps serve as valuable tools for understanding earthquake risks, but they are subject to limitations and uncertainties that can affect their accuracy in predicting future major earthquake accelerations. It’s essential to recognize these challenges and continuously update and refine these maps based on the latest scientific research and data. The ۱۲ November ۲۰۱۷ Sarepole-Zahab Mw۷.۳ earthquake, was a significant seismic event representative to its extensive damage in the affected areas. The acceleration values depend on the location and distance from the earthquake’s epicenter. The earthquake occurred in a zone for which a M>۷.۰ earthquake was not expected. The ۶ February ۲۰۲۳ earthquakes in southern Turkiye occurred in the East Anatolian Fault zone. The couple events were unexpectedly powerful and caused widespread damage to infrastructure, loss of life, and significant disruption to daily life in the affected areas. The occurrence of Mw۷.۸ and then Mw۷.۵ earthquakes in the same day. The mechanism and main shock of the ۲۸ March ۲۰۲۵ Myanmar earthquake are reminiscent of the ۶ February ۲۰۲۳ Karamanmars Turkey-Syria earthquakes. Weak structures also contributed to the catastrophic damage in both the ۲۰۲۳ and ۲۰۲۵ Myanmar events. Such level of seismic hazard might not be predicted by earthquake hazard zoning maps of Turkiye. The inefficiencies of seismic hazard zoning maps are studied and discussed herein.
