Easy HVSR allows the analysis of the spectral ratio of microtremors recorded with a single-station. The simplicity of use and speed of execution of the calculations allow the user to get immediate results in the estimation of: resonance frequency, stratigraphic profile and equivalent shear wave velocity Vs30, all according to the guidelines suggested by the SESAME project.

• Import of data from SEG2, SAF and ASCII files.
• Geographical location of the investigation site.
• The user can choose the appropriate methods for the directional sum of the traces in the horizontal direction, for the smoothing and for the bandwidth to be analyzed.
• All results are displayed in customizable charts.
• Automatic first estimate if the stratigraphic model that best approximates the H/V spectral behavior recorded in situ.
• Checks on the reliability of the H/V curve and its peak suggested by the SESAME project.
