Near the top of Japan’s Mount Ontake, whose recent eruption is thought to have claimed 36 lives, rescue teams have been facing setbacks due to the dangerous terrain including flying rocks and poisonous fumes. Around the same time, the Japanese Geographical Survey Institute (GSI) has posted nearly 200 photos of the initial eruption online from 360 degrees around it.
By overlaying the photos on a precise topographical map they hope the data can be valuable to teams by helping them understand the behavior of the plume and conditions all over the area. These photos are available for anyone to see by going to the GSI website, but perhaps its some of the videos posted from the scene online that give a better sense of the disaster.
