1995年1月17日，在兵库县南部和淡路岛地下17 km处发生了科比地震（MJMA 7.2，Mw 6.9）。为了研究这次大地震余震区的P波速度分布和地震学特征，爆炸地震研究小组（RGES）进行了广角和折射地震勘探。该剖面从北方京都府的京北，经科比，到淡路岛的西丹，全长135 km，包括6个炮点和205个观测点。每发子弹的药量为350-700公斤。P波速度结构模型显示了一个浅于2.5 km的复杂沉积层，一个2.5 km厚的基底层，其速度为5.5 km/s，覆盖在结晶上地壳上，以及上地壳和下地壳之间的边界。
Abstract The 1995 Kobe (Hyogo‐ken Nanbu) earthquake (MJMA 7.2, Mw 6.9) occurred on Jan. 17, 1995, at a depth of 17 km, beneath the areas of southern part of Hyogo prefecture and Awaji Island. To investigate P‐wave velocity distribution and seismological characteristics in the aftershock area of this great earthquake, a wide‐angle and refraction seismic exploration was carried out by the Research Group for Explosion Seismology (RGES) . The profile including 6 shot points and 205 observations was 135 km in length, extending from Keihoku, Northern Kyoto prefecture, through Kobe, to Seidan on Awaji Island. The charge of each shot was 350–700 kg. The P‐wave velocity structure model showed a complicated sedimentary layer which is shallower than 2.5 km, a 2.5 km‐thick basement layer whose velocity is 5.5 km/s, overlying the crystalline upper crust, and the boundary between the upper and lower crust.
