Located in the northwest corner of Nicaragua, Coseguina is a basaltic shield volcano with a large crater lake in the middle that's about half a kilometer deep. The volcano came into existence in 1835 with a huge eruption that showered all of Central America and even Mexico with ash and pumice. The lake started forming 60 years ago and the last eruption was a hundred and forty years ago but there are still some small emissions from fumaroles.
Yet another stratovolcano, Momotombo is located in the middle of the ring-of-fire which passes through western Nicaragua. It is located outside the city of Leon, which was rebuilt farther away from the volcano after Momotombo's 1606 eruption destroyed the orginal city. The last time it erupted was in 1905, the 15th time since the 16th century, but it has been experiencing a high number of daily earthquakes, some of the relatively strong, and the color of its gas emissions has changed to black.
One of Nicaragua's most active volcanoes, Telica has erupted intermittently since it was discovered back in the Spanish conquistador days. The Telica volcano group consists of several overlapping cones and vents with a general north-west alignment. Sixteenth century eruptions have been reported at Santa Clara, one of the Telica group volcanoes, but its eroded and breached crater has been covered by forests throughout historical time. Telica is stratovolcano with a steep-sided cone with a 700m wide double crater. Scientists have observed that activity at the volcano has been increasing for the last few years.
