Tsunami Analysis and the Fukushima Disaster

This weeks focus for Application in GIS was Tsunami analysis.  While the analysis we conducted was based on the Fukushima tsunami incident in 2011 and wasn't exactly for preventative planning, the results of the analysis could be used for future planning.  In preparation for this lab, we also did a module focusing on how to create feature datasets in ArcGIS as well as going a bit deeper into adding feature classes and rasters into geodatabases. 

For the lab analysis of the Fukushima disaster, we conducted two separate analyses.  One focused on the radiation spread from the Fukushima reactor meltdown and how distance affected how at risk one was and where people really needed to evacuate from.  The second analysis focused on the tsunami itself.  Using raster imagery, masks were made from the coast to 10,000km inland.  Using these masks and the already known land area that was affected, an evacuation zone plan was made to provide a layout for where safe land could be found in the event of another tsunami. 

The evacuation zones for the radiation zones were created manually using ring buffers centered on the Fukushima II power plant.  However for creating the evacuation zones for the tsunami affected lands, more automation was used by implementing a tool within ArcGIS called model builder.  Again, once these zones were created, the final map was created and can be found below.  I do ask if anyone has any issues with my color choices, please comment below with suggestions.  Living as a color blind individual does not always translate well in full color mapping. 

Enjoy!
