| 内容記述 | The P-wave travel times to Japanese stations were investigated. Kurile Islands earthquakes gave arrivals earlier than those expected from the Jeffreys-Bullen table. Neither location errors nor reading errors are likely to be the cause of this phenomenon. The early arrivals may be due to a high velocity structure beneath the Island Arc from the Kuriles to Japan. It is found that the upper boundary of this high-velocity structure is dipping toward south west and not shallower than 60km. Its thickness is increasing in the same direction and the lower boundary is not deeper than 400km. This pronounced anomalous structure could not be found in any direction other than that of the Kurile Islands. The seismic waves which travel in this anomalous region are less attenuated than those travelling elsewhere, especially in higher frequency range.|Nihon no kansoku ten made no P-ha no soji o shirabeta.
