Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Granada
A quarry exposes bedded oxidized scoria layers in a cinder cone of the fissure-fed Granada alignment. The cone was constructed along a semi-arcuate, N-S-trending fracture located between the city of Granada and the northern flanks of Mombacho volcano, east of the rim of Apoyo caldera. The lineament is also known as the La Joya alignment, after the explosion craters located SW of Granada. The alignment originated about 12,000 years ago, and its latest eruptions may have occurred as recently as about 2000 years ago. Photo by Lee Siebert, 1998 (Smithsonian Institution).

The Granada lineament, also known as the La Joya alignment, is an arcuate fissure extending from about 2 km SE of the Apoyo caldera rim around to N of the city of Granada. Small cinder cones are present about 8 km NNW from the Mombacho summit, and the N-S oriented La Joya maar explosion crater chain stretches over 1 km just SW of Granada city. This feature is structurally distinct from the Apoyo caldera and is analogous to the Nejapa-Miraflores alignment north of Masaya volcano. The lineament, characterized by the eruption of basaltic lavas and tephras compositionally similar to mid-ocean ridge basalts, originated about 12,000 years ago, and the latest eruptions may have occurred as recently as about 2,000 years ago.
