Three-dimensional empirical traveltimes: construction and applications

Nicholson, T; Sambridge, Malcolm; Gudmundsson, O


A new approach for predicting traveltimes is proposed which makes use of sophisticated smoothing and interpolation techniques applied to observations from large earthquake catalogues. The technique produces 3-D empirical traveltimes directly from a database of observations and does not impose any arbitrary spatial scalelength on the data, for example by smoothing observations over a pre-determined distance interval. This feature allows the spatial variability in data density, as well as...[Show more]
