GISCorps is a Peace Corps type of organization for GIS volunteers. In early May the call went out from UNOSAT (the UN's satellite imagery team) to many GIS folks including me for volunteers to help map damage from Cyclone Nargis. Unfortunately I could not handle the time commitment they needed but I often wish I had tried to make the time. Below is a portion of a map showing the extent of building damage in the Irrawaddy Delta region of Myanmar. GISCorps volunteers analyzed satellite images from before and after the storm and did a "change detection analysis" to arrive at these figures and maps.
Further information on this project and more maps can be found here.
