We digitized complete seismograms of the 1923 Kanto earthquake (M■ 7.9) observed at two regional stations, Tokushima and Sendai. The epicentral distances at Tokushima and Sendai are about 450km and 350km, respectively. We can see two pairs of peculiar P and S phases in the seismograms. By the travel time analysis, we found that the two pairs of the phases come from the two portions with the concentrated slip on the fault plane, respectively, estimated by Wald and Somerville (1993). We pointed out that for huge earthquakes seismograms at the regional sites are very important to understand detailed source process. キーワード(英): - 記事区分 - 区分    委員会論文集
