There are, what look to be, articulated lorries near the buildings on the right. They must be about 40' long.
There are scorch marks around where the middle of the 3 buildings on the left are, or rather were, possibly where the event happened.
Blast radius can be a moot point, but certainly significant damage occurred out to ~300'.
Dunno how that translates into quantities (and types) of rocket fuel. Or TNT!
Can't use YouTube at work but there are plenty of launch pad explosions to gauge the rocket fuel aspect.
