The combat log shows a simplified version of the combat results. The crush damage you are seeing is a total of all of the damage types done, and listed as "crush" damage because among the damage types done, crush damage was the type with the largest amount.
If you mouse-over that line in the combat log, a pop-up will display the detailed version of that combat event.
For example, the combat log may say "16 crush damage", and the pop-up may detail "13.1 crush damage + 3.3 burn damage".
-HOWEVER-
I'm not convinced that the damage is being calculated correctly, at least in the case of Lightning Strikes. (Turning Wheel damage seems correct, but I'm not certain.)
The damage from Lightning Strikes is supposed to be "+10% damage as shock damage", but it seems to be more like 5%.
For example, if I hit for 24 damage then the combat detail is showing something like "22.9 crush damage + 1.1 shock damage". 10% of 22.9 should be more like 2.2 or 2.3 shock damage, I would think. Smaller hits (say, for 13 damage) don't show any shock damage at all. In a case like that I'd be expecting to do around a point of shock damage if there were +10% shock damage.
So either I'm missing some aspect of how the game calculates the +10%, or there's a bug that's causing the damage to be calculated incorrectly, or Lighting Strikes is only supposed to do +5% damage as shock damage and the description is wrong.
