Earthquake-induced Landslides on Ancient Tomb Mounds in Japan

摘要

Landslides in an ancient tomb mound is described and discussed from an engineering geology viewpoint. The 'Keicho-Fushimi' earthquake of 5 September 1596 was considered to have triggered the landslide, which deformed the tomb mound. The modeling of landslide by using earthquake response analysis (FLUSH) and calculation of the cumulative permanent displacement by Newmark's method gives sufficient approximation to explain the field observations.
