Abstract
INTRODUCTION The Hyogo-ken Nambu earthquake of January 17, 1995 caused devastating damage in Kobe and surrounding areas. Total casualties were more than 5,500 and about one hundred thousand residential houses must be demolished (AIJ, 1995). After the earthquake different institutions sent damage survey teams to Kobe and unanimously found that the heavily damaged buildings and collapsed residential houses were concentrated in a narrow zone, the so-called "damage belt" oriented WSW-ENE across the city of Kobe. This strike of the damage belt coincides with the strike of the Rokko geological faults and also with the seismogenic fault plan (AIJ, 1995; Kamae and Irikura, 1995; Kikuchi, 1995) to Chuo-ward. Further to the east the damage belt starts to bend southward and so departs from the trend of the seismogenic fault plane, but it still follows the southern end of the Rokko geological faults. Since no surface breaks alond the Rokko geological faults...Keywords
