The stunning beauty of Maps, part III

History and current events are a great opportunity for GIS as they allow to disseminate pertinent information fast to those who need it. They bring out the best in map-making I posted here and here already. Not a few websites posted maps on the Japanese catastrophe, here are those I found from watching Al-Jazeera and my favourite blogs.

This show the earhtquakes over time leading up to the event, in a sparse yet colourful spatio-temporal display I looked for in my previous blog posting.
Breaking news: NHK World announced the Japanese Met Office upgraded the magnitude of the original event to 9.0 on the Richter scale: a 0.1 increase on a log10 scale is 2.5 times greater destructive force than originally measured!

Update 17 March: for social maps, here is a Trends map from ESRI's Disaster Response:
