N2 - We researched gravestones and stone lanterns displaced by the 2007 Noto Hanto Earthquake to reveal characteristics of the ground movement in the southern area from the epicenter. The displacements are classified into three types : overturning, translation, and rotation. In this paper, we discuss mainly the overturning of gravestones and stone lanterns. Percentages of overturning and displacement rates of gravestones indicate 35-61% and 76-100% respectively in the area within 10 km from the epicenter. Within 10-40 km from the epicenter, their percentages are generally less than 10%, though higher values of 40-92% were recognized in some limited areas of Nanao City and its vicinity, about 30 km from the epicenter. The higher values are measured on the hill slope surrounded by alluvial lowland. Overturning directions of Enchu-type stone lanterns are more efficient for analyzing ground movement because horizontal section at their base is circlular in shape. The study area is divided into seven zones characterized by specific direction of overturning. Some zone boundaries are controlled by topographic features. The directions of overturning are directly controlled by horizontal ground movements.
