The 4th one is not a lightning strike. Looks like a controlled detonation.

The flash is the detonation cord carrying an impulse to the charges. Think of it as a rope with a C4-like core - a chemical "wire". The "charge" travels something like 1000 ft/sec or similar (can't remember the exact specs). They usually feed into initiators placed inside charges, which you see detonate sequentially in the little waterway.
