Torsional mode of a dining table identified via GHM (Gaussian-filtered Horizontal Motion) analysis Here a suggested way to invest some of you time to get familiar with the GHM (Gaussian-filtered Horizontal Motion) method.
Such a method allows you to identify the eigenmodes of a structure (a tall building or the dining table in ...
HVSR @ Point A - time lapse in the 17-25 Hz frequency range This video animation is described in the paper "On the Identification of Industrial Components in the Horizontal-to-Vertical Spectral Ratio
(HVSR) from Microtremors" - GIANCARLO DAL MORO, Pure and Applied Geophysics (February 2020)

Time lapse animation of the HVSR [central Europe site] In the video you can see the amplitude spectra of the three components (vertical, NS and EW), the single HVSR curves (as the time goes by) and the updated mean HVSR curve. Also shown the coherence functions.

Introduction to the HoliSurface acquisition In this video we show the very simple acquisition of HS (and HVSR) data.
This is a methodology that "substitute" (and improve) the standard (and problematic) MASW technique.
