“…This estimation is based on the assumption that this relationship could be applied throughout the strong motion during the main shock. The linear relationship is confirmed by smaller aftershocks until 20 cm/s of PGV (Nishikawa et al, 2002). Assuming this linear relationship during the main shock on 11 th March 2011, it infer that the landslide was initiated by the complete loss of shear strength at the slip layer caused by an increase of excess pore water pressure during the strong seismic motion.…”

and infilling valleys. Such massive grading operations often resulted in inadequate compaction of fill materials creating areas of dangerously soft and weak ground within cities throughout Japan. In recent years, a significant number of valley-fill failures and fill slope failures have been reported during large earthquakes that centered in large cities (Kamai et al., 2002). One of the first landslides in a valleyfill was recognized in a suburb of Sendai City during the Miyagi
