An overflight on November 15, 1952 shows the crater half filled with viscous trachytic lava.  Sporadic small steam-and-ash explosions were observed during the overflight, and continuous weak steam emission took place from the center of the dome.  Montículo Cinerítico in the left background at the southern tip of the island is an eroded pyroclastic cone that preceded the 1952 eruption.
