How can rebuilding a city/large area be considered an economic boost?
It certainly creates an opportunity for the re-distribution of wealth.  Money will be transferred from insurance companies to construction companies.  Businesses that go under will be replaced by ones that survived. Some companies will make a profit out of this, but as you have already figured out, no new wealth is created by the disaster.  (Although lots has been destroyed, so we are looking at a net loss.)
