Landslide Investigation Using Seismic Refraction Tomography Method: A Review

Since the early 1960s, near-surface seismic refraction tomography (SRT) has been extensively used as a non-invasive and cost-effective geophysical method to characterize complex geological structures for landslide investigation. This technique is able slope material, sliding surface's geometry, mass movement, physical properties of media, water saturation effects on slope. Therefore, this become an appropriate due increasing progress novel algorithms improvements field-data collection systems. In paper, we attempt review essential research that investigated various types landslides influenced by materials identified in areas, since year 2000. Significant conclusions obtained applying different survey strategies data processing surveys are widely discussed concentrating advantages disadvantages method. The main results few available studies time-lapse SRT (TLSRT) particularly analyzed.
