The March 11th, 2011 Off the Pacific Coast of Tohoku Earthquake, also known as the Great East Japan Earthquake, has caused sand-liquefaction over a long stretch of landfills along the coast of the Tokyo Bay. An attempt was made to detect soil subsidence from raster images converted from airborne LiDAR (Light Detection and Ranging) data before and after the earthquake. To cancel out deep-seated tectonic displacements and systematic errors of LiDAR surveys, the template matching technique is used
