TEPCO has released a detailed map of the various facilities around the plant complex at Fukushima Daiichi. The map is helpful for locating facilities in relation to each other or identifying what something seen in a photo might be. The map below can be clicked on to open a larger version in a new browser tab. There is also an extensive list of the latitude & longitude coordinates for facilities and canals around the plant listed below the map on this page. This can be useful when using Google Earth to identify what is at a location.
