The failures of the road infrastructures due to a slope failure during an earthquake such as the 2008 Iwate-Miyagi earthquake and 2008 China Wenchuan earthquake are issued. The induced slope failures cause the various failure modes of road structures. We classified the failure modes of a road structure due to the slope failure by analyzing the 196 database on the damage of road structures in the 2008 Iwate-Miyagi earthquake from the view point of the geological features and the distance from
