Keywords:tectonics, wrinkle ridge, graben, restoration

The topography of tectonic features in northwestern Imbrium and Sinus Iridum were studied in detail using SELENE-LISM data to estimate the horizontal shortening achieved by the formation of the features. As a result, it was found that the shortening by the formation of mare ridges was smaller than previous estimations by two orders of magnitudes except for a ridge, along which shortening was as large as ~500 m at maximum.
