An immortal rumour wandering through the German press says: "Tornados only exist in the USA!". Even if a village is almost devastated, like in June 2004 Micheln, Sachsen-Anhalt, or in June 2003 Acht, Rhineland-Pfalz, you can read such a nonsense. Often enough, articles refer to a "mini-tornado".
The truth, however, is that Germany, would it be an American State, was in the tenth place there, as far as frequency and violence of tornados are concerned.
We have composed a graphic, which shows all known tornados that were at least as strong as the ones in Micheln and Acht. It is obvious, that they occur pretty often, whereby those in empty areas might not even be recorded. Therefore, the real number of severe tornados should be higher.
The most tornado jeopardized country of Germany is Lower-Saxony.
