In 2010, a group of scientists and explorers set foot on the shore of the lake of boiling lava in the depths of the crater of the volcano Nyiragongo, which lies at the center of the African Great Lakes region. The team wanted to walk on the shore of the largest lava lake in the world. Photographer Olivier Grunewald was a meter away from the lake, which gives us to enjoy the unique views of molten lava.
