ABSTRACT

ABSTRACT: This paper describes vertical array strong ground motion data obtained during the Hyogoken Nambu Earthquake (Kobe Earthquake) of 1995. The wave forms and the geotechnical conditions are provided as well as other related information for a number of sites. Based upon a series of vertical array data for aftershocks at Port Island, changes of geotechnical characteristics after the liquefaction were analyzed. The results shows sudden decrease of P-S wave velocities during the liquefaction and then gradually recovered to the original states. Some of these data are available for readers who want to work on the vertical array records.
