In response to the Tohoku Earthquake and Tsunami (Mar 11th 2011), CGA established a rapid response data portal.   With funding from the Reischauer Institute for Japanese Studies, the data layers were uploaded to an online webmap portal, where a number of additional data layers have been archived.   These resources comprise the geographic component of the long-term multi-media archiving project:  Digital Archive of Japan's 2011 Distasters.
