The Global Volcanism Program is not aware of any Holocene eruptions from Las Lajas. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Las Lajas page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Las Lajas volcano rises on the horizon NE of the flat-lying floor of the Nicaraguan central depression. The massive basaltic shield volcano is the largest Quaternary volcano east of the depression and contains a 7-km-wide caldera.

The SE side of the caldera of Las Lajas volcano is breached by a narrow canyon through which the Quebrada Las Lajas drains into Lake Nicaragua. The caldera walls of Las Lajas are up to 650 m high.

Las Lajas is the largest Quaternary volcano east of the Nicaraguan graben. The broad, low, basaltic shield volcano is truncated by a 7-km-wide, 650-m-deep caldera, whose SSW rim forms the horizon. In the foreground are part of a group of five coalescing andesitic-dacitic lava domes that are located in the center of the caldera. Additional domes are present on the outer flanks. Las Lajas itself is of probable Pleistocene age, but youthful cinder cones on the flanks are similar to those of the Nejapa alignment and may be of Holocene age.

The rounded lava dome in the center of the photo is a dacitic post-caldera dome that was constructed on the southern flank of the basaltic Las Lajas shield volcano. In addition to flank domes, five coalescing domes were constructed within the caldera.
