I am no expert but why that thing needs an explosive charge to release sarin?
Why not make it fragile and let simply open on impact? Crater does look like there was a serious explosion.
What I see on the picture is consistent with tube with sarin inside placed vertically and and then external charges on the upper end exploded and Sarin simply raptures the tube.
Sarin has low diffusivity. The Tokyo attacks released a couple of liters in enclosed, crowded, rush hour trains and only killed 12 people. The explosives are to disperse the gas (the link says like a "tube of toothpaste hit by a mallet"), in order to get a more widespread plume.
