A team has compiled numerous high resolution images of the volcano. http://www.physorg.com/news191248302.html. Most have been taken from a satellite, giving a unique view of the cloud as compared to what we see from the ground. The most interesting thing I found with this heat map visualization is the finding that as "the volcano's infamous ash plume is receding, its internal temperature is rising.". What this means is that just looking at the cloud, we would think things are getting better because it is getting smaller, but thats not the case and we must be even more cautious about what flys through the ash. The heat-map gives us a different view of the ash, and allows us to analyze more indepth.
