The lava flow from the volcano in La Palma reached the sea tonight, a few minutes after 11:00 p.m. (Canarian time), producing columns of smoke.
Specifically, it has done so in the vicinity of Los Guirres beach and also a nearby cliff, from which the lava would be falling from a height of nearly 100 meters.

The lava flow begins to form a lava delta
The lava flow that reached the sea on the island of La Palma on Tuesday night has begun to form a lava delta that "is slowly gaining ground on the sea", according to the Spanish Institute of Oceanography this Wednesday.
Lava deltas are formed by the solidification of lava upon contact with water. It cools and breaks in such a way that the fragments are deposited on the seabed and form an uneven surface. So far, there is no estimate of the size it has already reached.
The process will continue as long as the lava flow is maintained, so it will continue to grow, filling adjacent areas and even collapsing some already formed in others.
