The problem  seems to be that you are not keeping both sides equal. When you convertvdb for one side, make sure you match the settings on the other (i.e. Convert Fog to SDF). Also, turn off that vdbresample unless you plan on resampling the other side too.

It worked fine for me after that, no more exploding velocity.
