Scientific paper

To study the underground structure in the south-eastern part of the Kanto Plain and the Miura Peninsular, a seismic prospecting survey traverse with a length of 42 km was carried out between Midori Ward in Yokohama City and Miura City, Kanagawa Prefecture. There were three explosion sites and sixty observation sites. The results can be divided into four groups. First, the underground structure of the investigated area is approximately divided into two parts: the south and the north near the roots of the Miura Peninsular. Second, the north is characterized by a simple structure consisting of three gently sloping, almost horizontal layers with P-wave seismic velocities of 2.0, 2.3, and 3.0 km/s respectively (top to bottom) and a layer with a P-velocity of 4.7 km/s under these layers. The 4.7 km/s layer, whose lowermost point is 4 km beneath the surface, is located in the vicinity of Konan Ward in Yokohama City. Third, in the south there are three layers with P-wave velocities of 2.3-2.4, 3.6, and 4.7 km/s respectively. The 3.0 km/s layer found in the north disappears and is assumed to change to the 3.6 km/s layer instead. The uppermost depth of the 3.6 km/s layer is about 0.5 km, which displays upheaval structure near the middle of the Miura Peninsular. Finally, the underground structure obtained from the P-wave velocity profile in this study is in harmony with the supposed geological structure.
