Tanna Island, Vanuatu

It was getting dark pretty quickly as it was a cloudy day and no moon. You can see the two active vents in the Yasur Volcano with the one on the left constantly exploding, some larger than others, and the one on the right blasting less often but with more of a rumble so it seemed the more scary of the two. It is a 361m high pyroclastic cone with a nearly circular 400m wide summit crater.
