Oops.......

Wow.

That is truly amazing.

Worth the watch.

That is incredible. And sad.

WOW.

It is amazing to see "nature" work that way..

it is even more fascinating to know that humans caused that..

I remember reading about that once in a children's book about history's most spectacular failures. The book portrayed the disaster in a comic manner, but damn... There is quite an element of tragedy to that.

you should have seen the insurance claims.

Oh man....Literally, man.

This may be a first: cj, thanks for posting that!

triangulation is always a risky venture.

Amazing!

I love the guy at the end re buying his fish.

Sounds like the survey was the critical error. Funnny but in many failures it isn't one thing that is in error, but many, but kinda like the Monty Hall problem, Bayesian set up the conditions such that as one failure happens, the situation cascades into a whole number of conditional probabilities. That is, if the survey triangulation error hadn't occurred the consequence wouldn't have happened regardless of other errors.

BTW this is a classic event. One that is studied in many hazards analysis courses emphasizing simple "human" errors (assumption). Another classis one is the Metric Mishap lead to loss of NASA orbiter. No insurance claims here, just the loss of $125M.
