A broad-based effort to employ geospatial analysis and information sharing contributed greatly to the disaster response effort after the Great East Japan Earthquake on 11 March 2011. OGC standards played an important role.
Sinsai.info (http://www.sinsai.info), a crisis-mapping site that uses the Ushahidi platform, was launched 4 hours after the earthquake occurred. "Sinsai" means earthquake disaster in Japanese. Volunteers organized by Open Street Map Japan confirmed, geo-coded and uploaded more than 110,000 calls.
