抄録
In 1997-1998, integrated passive and active seismic experiments were conducted in northern Honshu, Japan. These experiments aimed at understanding the relationship between earthquake occurrence and deformation process of the intra-island-arc crust. In the summer of 1998, a shallow seismic reflection survey was conducted to obtain the fault’s detailed geometry to depths of 1km across the western marginal faults of Kitakami Lowland, Iwate Pref., Japan. The seismic source was a mini-vibrator. The data set recorded by the digital telemetry system was processed using seismic reflection technique. Imaging was preformed using conventional common mid-point processing steps, including post-stack migration and depth conversion. A reflection image shows the deep geometry of the Uwandaira fault, which is positioned at the eastern edge of the Ou Backbone range.
