Laze rising to the sky. Laze, a combination of the words lava and haze, is the product of a chemical reaction that happens when molten, 1200 degree Celsius lava hits the ocean. The sea water gets boiled, creating a potentially deadly mix of hydrochloric acid, steam, and tiny volcanic glass particles. The lava rivers covered a distance of 10 km from the fissure to the coast.
On the picture below, a helicopter is visible hovering above the lava river
