HoliSurface® (HoliSurface®)
Main tools:
- HoliSurface® analysis (patented methodology) that allows to jointly analyze all the surface-wave components obtained by using just one single 3-component (calibrated and triggered) geophone
- computation and modelling of the H/V Spectral Ratio (Nakamura’s method) to estimate the resonance frequency
- Vs30 calculation
- tool for Miniature Array Analysis of Microtremors (MAAM): Rayleigh-wave effective phase velocity dispersion curve from passive acquisitions performed while considering micro arrays (radius of very few meters)
- joint analysis of HVSR + MAAM dispersion curves
- joint inversion of HVSR + group-velocity spectra of one or more components (vertical and/or radial component of Rayleigh waves and/or Love waves)
- spectral analyses: computation of amplitude and phase spectra and spectrograms (frequency content over time)
- 1D modelling of refractions (also considering low-velocity layers) [see the paper "Unconventional Optimized Surface Wave Acquisition and Analysis: Comparative Tests in a Perilagoon Area"]
- elastic moduli tool
- tool for creating 2D sections
- vibrational analysis (DIN 4150 and UNI 9614)
- building vibrational analyses (coupled, uncoupled and GHM method)
- tool TCEMCD (Three-Component Extraction from Multi-Channel Data) to handle the joint acquisition of complex data
From release 6.0: - RPM (Rayleigh-wave Particle Motion) curve analysis
- SSR (Standard Spectral Ratio) to define the site resonance frequency
From release 2018: - tool for the Site Response computation

3D visualization of field and synthetic group-velocity spectra
Because of the novelty of the adopted procedures, the HoliSurface® software is offered only during one of our workshops or after the mandatory training day.
