3D Processing Software
HVSR Method Near-surface Detection
 

Micro motion H/V spectral ratio refers to the ratio of the horizontal and vertical components of seismic background noise at different frequencies recorded on the surface. In the field of engineering seismology, V is usually used to represent the vertical component of micro motion records, and H is used to represent the horizontal component of micro motion records. After measuring the H/V spectral ratio curve as a frequency function, based on a certain relationship (usually empirical), the relationship between the peak value of the H/V spectral ratio curve and the fundamental resonance frequency of the geological structure is established to estimate the thickness of sedimentary layers or site amplification factor, sometimes also known as the HVSR (Horizontal to Vertical Spectral Ratio) or QTS (Massi Transfer Spectrum) method
