An RV with (not full) of explosives exploded and caused damage that devastated an entire street block.

The explosion could be felt miles away, and far from ground zero, windows shattered.

My question is, what type of explosives can do such damage? I've seen videos of people throwing TNT into lakes, and the damage wasn't this big. The RV wasn't "packed" with explosives, so what sort of explosives can do this much damage? I only known of Chernobyl and atomic weapon testing that had shockwaves felt that far out.
