The Mt. Etna is characterized by complex geological, volcanic and seismological dynamics, making geophysical site characterization particularly challenging. This work presents a harmonized database of Horizontal‑to‑Vertical Spectral Ratio (HVSR) measurements acquired across multiple municipalities in the Etna area, including both urban and rural sites. The dataset integrates field surveys conducted by different teams using standardized acquisition and processing procedures. All recordings were validated through HVSR consistency checks, metadata verification, and cross‑comparison among different instruments. The database provides a valuable resource for seismic microzonation, site‑response numerical modelling, and multidisciplinary studies on the Mt. Etna region. It is intended to support both ongoing research and future investigations by the scientific community.

Abstract
The Mt. Etna is characterized by complex geological, volcanic and seismological dynamics, making geophysical site characterization particularly challenging. This work presents a harmonized database of Horizontal‑to‑Vertical Spectral Ratio (HVSR) measurements acquired across multiple municipalities in the Etna area, including both urban and rural sites. The dataset integrates field surveys conducted by different teams using standardized acquisition and processing procedures. All recordings were validated through HVSR consistency checks, metadata verification, and cross‑comparison among different instruments. The database provides a valuable resource for seismic microzonation, site‑response numerical modelling, and multidisciplinary studies on the Mt. Etna region. It is intended to support both ongoing research and future investigations by the scientific community.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
