Once-in-a-century is averaged over many centuries. Sometimes things cluster.
In 2002 parts of Europe were hit by a once-in-a-century flood [1].
In 2013 pretty much the same parts were hit by a flood that in many places were worse than the 2002 flood [2]. For instance, in Passau (on Donau), the waters were the highest since 1501 [3].

- calinet6 12y agoOne of the least understood facets of statistics. In random or natural distributions, we do not expect any kind of evenness or predictable spacing. Clustering of seemingly random events happens and happens often. Only when averaged over a sufficient number of samples can we make sense of patterns.
