Utilizing High-Frequency Seismic Signals (HFSS) and other geophysical methods to locate potential sinkhole collapses: a case study from West of Alexandria, Egypt

Analysis of microtremors, especially the high-frequency seismic signals (HFSS), emitted from shallow sources in the frequency domain 20–20,000 Hz, can be used in investigating various hazard causes, such as landslides, sinkholes, avalanches, shallow cavities and many other applic...
