Sintesi geologica
Momotombo is a young stratovolcano that rises prominently above the NW shore of Lake Managua, forming one of Nicaragua's most familiar landmarks. Momotombo began growing about 4500 years ago at the SE end of the Marrabios Range and consists of a somma from an older edifice that is surmounted by a symmetrical younger cone with a 150 x 250 m wide summit crater. Young lava flows extend down the NW flank into the 4-km-wide Monte Galán caldera. The youthful cone of Momotombito forms an island offshore in Lake Managua. Momotombo has a long record of Strombolian eruptions, punctuated by occasional stronger explosive activity. The latest eruption, in 1905, produced a lava flow that traveled from the summit to the lower NE base. A small black plume was seen above the crater after a 10 April 1996 earthquake, but later observations noted no significant changes in the crater. A major geothermal field is located on the south flank.
Sintesi da Wikipedia
Riassunto in ingleseMomotombo is a stratovolcano in Nicaragua, located near the city of León. It stands on the shores of Lake Managua. An eruption of the volcano in 1610 forced inhabitants of León, in the Spanish Empire, to relocate about 48 kilometres (30 mi) west. The ruins of the city are preserved at León Viejo. It also erupted in 1886, 1905 and most recently on 30 November 2015 and 28 February 2016.
