An Indonesian miner carries baskets of solid sulphur from the quarry in Kawah Ijen, an active volcano in the remote Banyuwangi regency in East Java on June 15, 2016. By day, traditional miners brave the highly toxic gases to extract huge chunks of sulphur from the shores of a large turquoise lake within the crater. #

Brilliant blue flames light up the night sky above Kawah Ijen on June 15, 2016, casting an eerie electric glow as they flow down the sides of the active volcano. Hot sulphuric gases -- escaping at high pressure through cracks in this legendary mountain -- ignite upon contact with air, burning a fantastic, iridescent blue. #

An aerial view shows the Pacific island of Nishinoshima, also known as Rosario Island, where researchers started surveillance activities for the first time since its eruption in 2013, some 1,000 kilometers south of Tokyo, Japan, on October 20, 2016. The 2013 eruption created a new island that merged into the older Nishinoshima island, creating this new landmass approximately 1 kilometer wide. #

Indonesia's Mount Soputan volcano spews lava and ash during an eruption as seen from Silian 3 village in Minahasa Tenggara, Indonesia's Sulawesi island, on January 5, 2016. #

The Volcano of Fire (El Volcan del Fuego) releases lava, seen from Escuintla, Guatemala, on January 4, 2016. Officials asked nearby communities to remain vigilant amid a state of yellow alert. #

June 23, 2016. A Hawaiian Volcano Observatory (HVO) geologist collects a fresh lava sample from Kilauea volcano for chemical analysis. The lobe being sampled was typical of the many scattered pāhoehoe breakouts along the flow margin. #

June 29, 2016. The lava flow front from Kilauea volcano reaches base of the pali, burning vegetation. The front consisted of ʻaʻā that was fed by a narrow channel extending down the steep section of the pali. #

Visitors look at lava from Kilauea as it flows toward the ocean in Volcanoes National Park near Kalapana, Hawaii, on August 8, 2016. The current lava flow erupted from a vent on the volcano in May and made its way to the sea in late July. Visitors can hike about 10 miles round trip to see the lava, or take a boat or helicopter tour to see the flow. #

Kīlauea lava continues to flow into the ocean at Kamokuna on September 30, 2016. A large skylight was visible to observers on the 61g upper flow field, exposing the flowing molten lava below the solid crust above. In this image, the skylight is about 5 m or 16 feet wide. #

Lava cuts across a road, flowing into the ocean on July 29, 2016. The ocean entries are adding lava to the rubble at the bottom of the sea cliff. Black sand—formed by the interaction of hot lava and cool seawater, as well as by wave erosion of the rocky cliff—is also accumulating along the coastline. #
