Abstract: Abstract Horizontal-to-vertical spectral ratio (HVSR) of both earthquake and ambient noise are applied to perform inversions of the subsurface velocity structure of a certain site, however, their mechanisms differ significantly. A comparative study on earthquake… read more here.

Abstract: The horizontal-to-vertical spectral-ratio (HVSR) analysis of ambient noise recordings is a popular reconnaissance tool used worldwide for seismic microzonation and earthquake site characterization. We have expanded this single-station passive HVSR technique to active multicomponent data.… read more here.
