Fukushima Daiichi nuclear power plant depiction
The crisis at the Fukushima Daiichi nuclear Power Plant continues. After hearing much talk about the various reactors, the evacuation zones and so on, I got curious as to what, exactly the scale of the event really was. That curiosity, plus a couple hours of work in Depiction, turned into a pretty extensive depiction of the region surrounding the power plant.
To view the file, you’ll need Depiction or the free Depiction Reader.
The depiction includes data and imagery from:
- The New York Times report on the model used by the US government to determine suggested their evacuation zone.
- The Wikipedia article on the power plant
- The Japan Ministry of Land, Infrastructure and Transport (via Wikimedia Commons)
- The US Army Map Service, via the University of Texas
- The USGS Shakemap Archive
- NGA shapefiles of flooding & damage
- And, of course, OpenStreetMap
I also used the Depiction Preparedness Add-on and one of our handy icon packs.
I hope this will be valuable to anyone who is trying to get a sense of the situation in Japan–it also happens to very nicely demonstrate Depiction’s powerful capabilities in combining multiple diverse types of data, which is nice, too.
If you have any questions–or suggestions–please post them in the comments!
UPDATE: I’ve uploaded a new version of the depiction–yesterday the US Department of Energy released a map that outlined the results of aerial radiation monitoring in the Fukushima area. I’ve included that map, as well as shapes extrapolated from that information. I’ll put up a post later about how I did that.
Additionally, I added a new batch of earthquakes from the USGS feed. It appears that the links included in the epicenters of quakes older than 7 days no longer work. That is, unfortunately, due to the way that the USGS outputs their data and archives older quakes. You can still find them, if you’re really curious, here–but only for the next couple weeks.

Could you send me the NGA shapefile data? The weblink no longer works. Thanks!

Granted, although not strictly weather related,occurences of rogue waves also known as extreme waves are dangerous and spontaneous ocean waves that are born far out at sea, and are a threat even to ocean liners.In oceanography, they are technically defined as waves whose height is more than twice the significant wave height (SWH), this measurement is dependant on observing a series of waves to determine the largest third of waves. Therefore rogue waves are not necessarily the largest waves found at sea; they are, indeed, large waves for a given sea state.
