To provide some sense of how much energy 1400 tons of TNT
produces, the Hiroshima bomb was some 15,000 tons, so the Cuban
event was about 9% of that.
The GBU-43/B MOAB (Mother Of All Bombs) which was dropped in
Afghanistan and is said to be the most powerful non-nuclear weapon in
the American arsenal has a yield of 11 tons of TNT, so the Cuban event
was equivalent to about 127 MOAB bombs.
So the explosion over Cuba would certainly get your attention!
The Tunguska event was in a different league again, with a blast
estimated to be equivalent to 1 Megaton.
The largest hydrogen bomb ever detonated had a yield of about 50 Megatons.
There are estimated to be between 10,000 to 15,000
H-bombs at the moment in the world. Given there are about 4037
cities in the world with populations over 100,000 people, there will
be enough H-bombs to share around with just about everyone you know.
