We compared the liquefaction site generated by the Kumamoto earthquake with the liquefaction hazard map of Kumamoto city. After that, we compared the common points of the liquefaction hazard maps of Kumamoto City and Nagoya City. Based on the results, we examined the ideal liquefaction hazard map for Nankai Trough earthquake. In the preparation of the liquefaction hazard map, it is general to use the boring data etc. to judge the degree of risk in the form of mesh. However, the engineering approach alone may miss the old ponds and the remnants of the river marks.
