San Cristobal, Nicaragua : an earthquake measuring 2.7 degrees occurred north of San Cristobal volcano.

The surveillance bulletin of volcanic activity .

At 9:35 this morning, January 22, 2016, an earthquake measuring 2.7 degrees occurred north of San Cristobal volcano. No significant change was observed in the behavior of this volcano.
The seismic amplitude live RSAM remains at low values, less than 40 units and emission of volcanic gases is low.

The San Cristóbal volcanic complex, consisting of five principal volcanic edifices, forms the NW end of the Marrabios Range. The symmetrical 1745-m-high youngest cone, named San Cristóbal (also known as El Viejo), is Nicaragua’s highest volcano and is capped by a 500 x 600 m wide crater. El Chonco, with several flank lava domes, is located 4 km W of San Cristóbal; it and the eroded Moyotepe volcano, 4 km NE of San Cristóbal, are of Pleistocene age. Volcán Casita, containing an elongated summit crater, lies immediately east of San Cristóbal and was the site of a catastrophic landslide and lahar in 1998. The Plio-Pleistocene La Pelona caldera is located at the eastern end of the complex. Historical eruptions from San Cristóbal, consisting of small-to-moderate explosive activity, have been reported since the 16th century. Some other 16th-century eruptions attributed to Casita volcano are uncertain and may pertain to other Marrabios Range volcanoes.
