Ah yes. It's my bad. "The most powerful earthquake ever recorded in Japan, and the fourth most powerful earthquake recorded in the world since modern seismography began in 1900" can never be classified as a Black Swan event, and I apologize for my mistake.
As for tsunami,
"The sea walls in several cities had been built to protect against tsunamis of much lower heights. Also, many people caught in the tsunami thought they were on high enough ground to be safe. According to a special committee on disaster prevention designated by the Japanese government, the tsunami protection policy had been intended to deal with only tsunamis that had been scientifically proved to occur repeatedly."
My apologies, this wasn't a Black Swan event either. Totally predictable, and not beyond what's normally expected.

It's funny how all Nostradamuses "prove" their vague predictions only after something occurs.
What was it said about black swan events?
"The black swan theory or theory of black swan events is a metaphor that describes an event that comes as a surprise, has a major effect, and is often inappropriately rationalized after the fact with the benefit of hindsight."
