[HQR05-12] Relation between with distribution of liquefaction-fluidization phenomena at the 2011 off the Pacific coast of Tohoku Earthquake and distribution of the Holocene strata
Keywords:the 2011 off the Pacific coast of Tohoku Earthquake, liquefaction-fluidization, Tokyo bay reclaimed land, Man-made strata, Holocene strata
Strong waves were simulated by SHAKE method on strong motion data in Shimosa Group at reclaimed land in Chiba city at the survey sites in the paleo-valley and out of the paleo-valley, neighbor sites.
On Mamagawa belt, JMA intensity 6- in the paleo-valley and 5+ out the paleo-valley were calculated. On Ebigawa belt, JMA intensity 5+ in the paleo-valley and 5- out the paleo-valley were calculated.
