A little bit about risk.
It's funny. Just now, I read a message on my sister's facebook. She moved to Arnhem recently, and on the 8th of this month, there was an earthquake near there. I hadn't heard of this in the following days (I don't follow the news), nor any time before. But I did know that near Holland, in the south east, was an area in Germany with slightly elevated risk of quakes.
The magnitude of this quake was not that great: 4.5 was within what I thought possible, though I didn't expect it to happen in my lifetime. Shows how little I knew. And I bet most people thought we were sitting on a stable sandy/muddy plate at the end of some big rivers. 4.5 on the Richter scale causes cracks and ruptures in buildings and infrastructure, but such a force is not yet a catastrophe. Certainly, chemical plants and nuclear reactors can handle that kind of shake. In fact, as it is reported
here [link in dutch], they should be able to withstand earthquakes up to 6.5 on the Richter scale.
However, recent geological research into the history of earthquakes in the affected region shows that during Roman times, there has been an earthquake with a Richter force of 7. And in geological terms, that's recent enough to predict that on this active ridge, there will be another one of that scale, at some unknown time in the future. With the presence of one of the largest chemical plants in the country straddling the break line, and several nuclear reactors nearby, that is inconvenient, at least. We may have fallen into the trap of thinking that the worst (natural) disaster that could happen in our country is massive flooding. And that wasn't even a factor in the slightly higher south east.
France is pretty much reliant on nuclear energy. Let's hope for the rest of Europe they do have their geological data in order, and that subsequent heavier quakes will stay clear of any unprepared, dangerous sites, such as the ones we apparently have here in Holland.
