17 Italian seismometer sites were investigated using an active-source Spectral Analysis of Surface Wave (SASW) approach. The study measured shear wave velocities for the upper 100-200 meters of the soil column at sites affected by the 1997-98 Umbria-Marche earthquake sequence. Data was collected by the Servizio Sismico Nazionale and other agencies, with a summary provided by the USGS.
Use Cases
- Modeling site-specific seismic amplification based on shear wave velocity profiles
- Calibrating ground motion simulations for the Umbria-Marche region
- Assessing geotechnical properties for earthquake-resistant construction
- Studying the relationship between soil structure and recorded earthquake motions
Strengths
- Shear wave velocity profiles are derived for 17 specific sites
- Measurements cover the upper 100-200 meters of the soil column
- Data is linked to a well-documented seismic sequence with eight magnitude 5-6 events
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
