Data Set Description [ Obrebski et al. (2010) ] The dataset of the multi-frequency compressional model, DNA09-P is derived from 58,670 traveltimes of direct P from 127 earthquakes measured in four frequency bands. The dataset used for the shear model DNA09-S includes 38,750 travel!time measurements, 34,850 S-wave observations from 142 events and 3,900 SKS observations from 24 events.
