The flash miscaptioned as lightning bolt in the shared video is an igniting Det Cord (Detonation Cord) before reaching the explosives, which is part of controlled underwater explosion. The video was previously uploaded in 2012 by Rannikon Merityö, a Finnish water engineering company.

PdL Support Systems: “Detonation Cord consists of a high-explosive (either PETN or RDX) core wrapped in a reinforced, waterproof, olive-drab plastic coating that transmits a detonating wave. It is used as a detonating agent, a priming agent or alone as an explosive charge. It can be initiated by an electric blasting cap or non-electric blasting cap. When the explosive core is detonated by a blasting cap, the wave travels along the cord to other blasting caps or explosive charges attached to it. It has a detonating velocity of not less than 5,900 m/s which makes it suitable for synchronizing multiple charges, even when placed at different distances from initiation.” [3]
