On April 25th, a 7.8 magnitude earthquake stuck Nepal approximately 50 miles northwest of Kathmandu. With the coordination of Kathmandu Living Labs and the Humanitarian OpenStreetMap Team, a global volunteer effort to map roads and buildings in the affected area is under way. OpenStreetMap data is being used by the American Red Cross, the World Bank, and other organizations to support response and recovery activities in Nepal.

This site provides basic statistics describing the work of OSM volunteers in the response to this disaster. The data is based on hashtags used in changset comments and therefore undercounts the total amount of contributions occurring at this time.

This site is no longer tracking live editing statistics. We thank you for all the hard work done in this unprecedented response effort.
