The Momotombo Volcano, reaching 4,199 feet (1,280 meters) above sea level and is described as the smoking terror, was one of the most active volcanoes in Nicaragua. This volcano was and still is one of Nicaragua's most popular tourist attractions for its physical features. The Momotombo Volcano is known for its frequent eruptions, with 10 confirmed eruptions between 1858 and 1905. In 1998 Lieutenant Walker of the U.S. Navy came to Nicaragua for a potential canal route. When he went near the Momotombo volcano he described it as a lofty, sulfur-stained peak emitting large volumes of vapor from the summit. This plume in this image may be similar to what Walker was talking about. 7 years after Lieutenant Walker came to Nicaragua (1905) Momotombo erupted. More than 100 years later in 2015 another eruptive phase began. As you can see in the picture a lava channel runs down the eastern flank of the volcano. This channel was there before the 2015 eruptions so when they happened the lava had an easy path to flow down. Around the Momotombo Volcano, there are geothermal fields and they have been used to make energy since 1983.
