We study location specifying method on the road. This paper describes specifying locations which are damaged by the 2016 Kumamoto earthquake on roads managed by Kumamoto Prefecture. We analyzed the expression of the announcement of damaged locations, investigated location gathering in the disaster situation by interview with the road administrator, and specified the locations from the announcement through maps and field investigation. In location specifying, there were some locations we could not specify and there were some locations we had mistaken. Improving the situation, we have developed "Road Geocoder" which shows candidates of location on roads using various geographical identifiers filtered through coordinates of road.
