I don't think the other two neighbouring hexes contribute much. Maybe a +1 or so to damage.

Doing the HT calculation I get 14.5 pts of damage (4D) for the occupied hex and 1/3rd that much for occupied hexes adjacent and 1/6 that muhc for hexes beyond those..
If anyone wonders I multiplied the actual weight (.066) x the REF (1.8 for PETN) and then took the square root and multiplied that by 42 (damage for 1 lb of TNT). I believe that's the right order for the operations.
I don't necessarily trust the formula for explosive charges so small.
