It depends a bit on how far you extend the implications of such an event.

If it was mistaken for an ICBM from North Korea, then rockets might be
launched in retaliation, and wars started. (It might be a deliberate
mistake if a government wanted an excuse to start a war).

If it was treated as a terrorist explosion, panic reactions could be
almost anything.
Look at the huge losses inflicted on US freedom and the US economy
caused by flying a plane into a skyscraper. (Again, it might be
deliberately mistaken for policy reasons).
