Evaluation of landslides using ambient noise measurements (case study: Nargeschal landslide)
A landslide is a destructive phenomenon that often takes hundreds of lives and causes serious financial damage each year. So, evaluation of landslides and identification of their complexity are of great importance. Ambient noise measurements provide a practical way to evaluate the geometry of landslides. Ambient noises are weak, small-amplitude vibrations recorded on the ground surface. This method is fast, low-cost, and nondestructive, and the accuracy of its results is appropriate. This study used ambient noise measurements at 30 sitesand analyzed them by the HVNR method to identify the fundamental frequency, amplitude, and directional resonance. Then, the results of the ambient noise measurements were compared and verified using geological and geotechnical data in the study area. The results establish that the simultaneous use of ambient noise measurements and conventional geotechnical methodsis an ideal combination for comprehensive landslide evaluation.
