Humans are terrible at evaluating rare but expensive failure modes. Nuclear power is far safer than just coal mining operations, even taking into account accidents.
At least now, if a Tsunami hits Germany, we are safe.
If a tsunami hits Germany, places like Kiel will be screwed. The Netherlands too. Most of Germany will be fine.
Deaths from Tōhoku earthquake and taunami: 16,000
Deaths from subsequent nuclear plant issue: maybe 300 long term
Tsunami in the Baltic Sea (or North Sea, for that matter)?! How's that supposed to happen?
Lots of ways. Imagine a meteorite strikes the North Sea for instance (tongue-in-cheek).
I think the parent's comment may have been glib.
Tsunami in Germany would have to be caused by a meteorite in the near sea, so you are not safe :P
Could as well be caused by a major submarine landslide of the Norwegian continental shelf. There's some evidence that this did happen at least once in the (geological) past.
