Ground-motion records, site profiles and amplification factors from the Groningen field, the Netherlands ...

A comprehensive database that has been used to develop ground-motion models for induced earthquakes in the Groningen gas field is provided. The database includes more than 8,500 processed ground-motion recordings from 87 earthquakes of local magnitude ML between 1.8 and 3.6, obtained from a large network of surface accelerographs and borehole geophones at 50 m intervals to a depth of 200 m. The 5%-damped pseudo acceleration spectra and Fourier amplitude spectra of the records are also provided. Measured shear-wave velocity (VS) profiles, obtained primarily from seismic CPTs, are provided for 8... Mehr ...
