Potentials and pitfalls of permafrost active layer monitoring using the HVSR method: a case study in Svalbard [PDF]

Earth Surface Dynamics, 2019
Time-lapse monitoring of the subsurface using ambient seismic noise is a popular method in environmental seismology. We assess the reliability of the horizontal-to-vertical spectral ratio (HVSR) method for monitoring seasonal permafrost active layer ...
