Implementation of Ibs-von Seht and Wohlenberg regression method. Investigation of seismic signals directionality.

OpenHVSR Processing Toolkit (OpenHVSR-ProTO)

OpenHVSR-Processing-Toolkit is a computer program developed in Matlab® (R2015b) by Samuel Bignardi Ph. D. and released under license GNU General Public Licens Version 3. It is engineered for the investigation of microtremors (seismic noise) by means of the Horizontal-to-Vertical Spectral Ratio (HVSR or H/V).

It is specifically designed to enhance single-station microtremor processing with the purpose of spatially correlating different forms of informative data content, fast map creation, and display of the results in 2D and 3D.

The user interface is designed to be user friendly while tightly binding processing and visualization so that the effects of different processing choices can be immediately evaluated. Furthermore, bedrock mapping capability, as introduced by Ibs-von Seht and Wohlenberg (1999) is included both through the computation of bedrock depth via a set of published regression laws or alternatively, by computing a customized regression based on the data at hand. The program aims at implementing the most effective and desirable processing tools present in other commercial and non-commercial alternatives, all in one bundle and freely available to the scientific community. In ad­dition to incorporating and enhancing currently available state of the art tools, I have integrated several original features that are not present in any other program. OpenHVSR-Processing-Toolkit naturally integrates with my previous data inversion software, OpenHVSR-Inversion, published in 2016. Together, they constitute a complete workflow for the Horizontal-to-Vertical Spectral Ratio method. I expect software to be of great use to researchers and I hope it will constitute the basis for further collaborative development toward future releases oriented at exploring the potentials of this technique.
