Title
Global Seismic Traveltime Database
Abstract
We have constructed a data base of seismic traveltimes, which was used to improve our seismic tomography model. We measured absolute arrival times of several seismic phases such as P, PcP, S etc by manual picking and differential travel times between PP and P and differential travel times of P-wave between two stations using waveform cross-correlation method. We use both of broadband and short period waveform data collected from all over the world including ocean bottom seismometers. At present, we have measured totally about 80,000 of various types of traveltimes.
