Why don't they report banks getting blown away in a tornado?

Answer 1

Except in the most violent tornadoes, structures generally are not blown away unless they are weak or poorly anchored, though they may still be destroyed. Banks are generally very sturdy structures. To blow a bank away would require a tornado of EF5 intensity, the highest rating possible. Tornadoes this strong are very rare. Since the new scale went into effect in 2007, 9 tornadoes have been rated EF5. Three of those tornadoes struck banks, and only one of those banks was hit by the full force of the tornado.

The first case was in Parkersburg, Iowa on May 25, 2008. The worst part of the tornado missed the bank, which was badly damaged, but remained standing.

The second case was in Joplin, Missouri on May 22, 2011. The bank was destroyed with all exterior walls swept away; only the vault remained in place.

The third case was in Moore, Oklahoma on May 20, 2013. The Federal Credit Union was demolished, with only the vault left intact.
