Explore Deception Island, the Active Antarctic Volcano That’s Home to [Chinstrap] Penguins | National Geographic

Over 100,000 breeding pairs of penguins nest on this island—which also happens to be an active volcano.

I had the privilege to see Deception Island and its penguins and other birds.

A large volcanic eruption shook Deception Island, in Antarctica, 3,980 years ago, and not 8,300, as it was previously thought, according to an international study published in Scientific Reports, in which researchers from the Institute of Earth Sciences Jaume Almera have participated. This event was the largest eruption in the austral continent during the Holocene (the last 11,700 years after the last great glaciation on Earth), and was comparable in volume of ejected rock to the Tambora volcano eruption in 1815. The eruption formed the caldera of the volcano, one of the most active in Antarctica, with more than 20 eruptions registered in the last 200 years: here.
