To get a high quality tomogram in seismic tomography, it is necessary to examine travel-time data carefully before inputting them to a reconstruction program. However, it has not been well known how to examine those data. In this study, the author tried to find some characteristics of first arrival traveltime curves obtained by crosshole seismic measurements. As the results of numerical experiments, it is found that the traveltime reciprocity and the parallelism among traveltime curves are valid for crosshole measurements as well as surface refraction surveys. Based on the results, the author proposes a method for examination and adjustment of traveltime curves for seismic tomography, which must improve the quality of tomography results. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
