Details for: Nejapa-Miraflores
Laguna de Nejapa (right center) and Cerro Motastepe (left-center horizon) are part of the N-S-trending Nejapa-Miraflores alignment. A series of pit craters and fissure vents extends into Lake Managua (barely visible at the far upper right) and is continuous with the volcanic vents on the Chiltepe Peninsula (far right horizon). The Nejapa-Miraflores alignment (also known as Nejapa-Ticoma) has been the site of about 40 eruptions during the past 30,000 years, the most recent of which (from Cerro Motastepe) occurred less than 2500 years ago.
