Data Driven Journalism – Mirko Lorenz: “August 6, 1945 was the day when an atomic bomb was dropped on the city of Hiroshima, 70 years ago from today. It is a sad fact that even the biggest atrocities and catastrophes loose part of their threat when time passes on. People forget. People who were present and survived die of age. So, gradually the event vanishes into history. What happened in the distant past might or might not be a hint at risks in the future. The bombings of Hiroshima and Nagasaki are different. Until this day the use of two atomic bombs, the destruction, the high toll of deaths and the aftermath are present in our collective mind. How can we best report about these events today? One very clear approach is demonstrated by the “Nuke Map” mash-up. It is an interactive page where users can see how the explosion of the Hiroshima bomb (or other, even more powerful nuclear weapons) would have affected the area they know.  The visualization/app can be found here.”
