3D laser survey of Japan earthquake damage

摘要

StreetMapper, the vehicle-based laser mapping system, is being used to assess the damage caused by the Japanese earthquake of the 11 March 2011. The mobile mapping system, purchased from Mirukuru and operated by Asia Air Survey, has been used to capture highly detailed 30 survey data. This data will be used to assess the structural damage caused by the earthquake and tsunami, as well as the effects of soil liquefaction. The Tohoku or Great East Japan earthquake was the most powerful earthquake known to have hit Japan and one of the ten most powerful in the world since modern record keeping began in 1900. The quake then triggered a destructive tsunami with waves of 38.9m travelling up to 10km inland. Asia Air Survey had just taken delivery of StreetMapper, which its has named Geomaster Neo.
