Zavadovski island is known as the smelliest place on Earth because of the sulphuric air that emanates from the volcano.

The first time that Zavodovski Island had been witnessed erupting was in July 2016, showering the penguins in ash. However, there is evidence that it erupted in the 1970s, possibly in the 1980s and as late as 2012.

In January 2018 "Planet Earth II" was a recipient of a Gold Award (Films on Nature / Environment / Wildlife category) in Virgin Spring Cinefest, in India.

In December 2017 "Planet Earth II" was awarded Best Film on Nature / Environment / Wildlife in Calcutta International Cult Film Festival, in India.
