Explanation: Volcano Tungurahua erupted spectacularly last year. Pictured above, molten rock so hot it glows visibly pours down the sides of the 5,000-meter high Tungurahua, while a cloud of dark ash is seen being ejected toward the left. Wispy white clouds flow around the lava-lit peak, while a star-lit sky shines in the distance. The above image was captured last year as ash fell around the adventurous photographer. Located in Ecuador, Tungurahua has become active roughly every 90 years since for the last 1,300 years. Volcano Tungurahua has started erupting again this year and continues erupting at a lower level even today.

Tungurahua is an active stratovolcano also known as the “The Black Giant.” It has a 600 ft. (183 m) wide crater. Most of the volcano is covered by snow. It causes many tremors in the nearby city of Banos. Tungurahua’s lava is mostly composed of basalts. Tungurahua has had at least seventeen eruptions in historical times, its most recent occurring in 1944 when it erupted explosively from its central crater. Located about 25 miles (~40 km) west of Tungurahua is the largest volcano in Equador, Chimborazo and to the north about 50 miles(~80 km ) is Cotopaxi volcano.
