Syrian tank is hit by HEAT round. Anyone in tank is killed instantly by spall, HEAT jet fragments, temperature, and massive pressure wave - forces involved are immense.
A few seconds later, the propellant magazine (T-72 uses two piece ammunition,) which is unprotected and encircles the turret in the T-72, begins to burn, after being perforated by numerous white hot fragments.
The propellant goes off - 50 rounds worth of tank shell propellant burning. Tank essentially becomes rocket engine chamber and the hatch is the nozzle, massive jet of flame results. Interior of tank is 2000 degrees F or so due to being massive rocket engine chamber.
