摘      要：The Mw 6.8 Adassil earthquake that occurred in the High Atlas on September 8,2023,was a catastrophic event that provided a rare opportunity to study the mechanics of deep crustal *** research aimed to decipher the rupture characteristics of the Adassil earthquake by analyzing teleseismic waveform data in conjunction with interferometric synthetic aperture radar(InSAR)observations from both ascending and descending *** analysis revealed a reverse fault mechanism with a centroid depth of approximately 28 km,exceeding the typical range for crustal *** result suggests the presence of cooler temperatures in the lower crust,which facilitates the accumulation of tectonic *** earthquake exhibited a steep reverse mechanism,dipping at 70°,accompanied by minor strike-slip *** the geotectonic framework of the High Atlas,known for its volcanic legacy and resulting thermal irregularities,we investigated the potential contributions of these factors to the initiation of the Adassil *** seismicity within the lower crust,away from plate boundaries,calls for extensive research to elucidate its implications for regional seismic hazard *** findings highlight the critical importance of studying and preparing for significant seismic events in similar geological settings,which would provide valuable insights into regional seismic hazard assessments and geodynamic paradigms.
