Random pictures | |  Nevado Cayambe is a massive volcanic complex in northern Ecuador, 60 km NE of the city of Quito and only 15 km E of the 20,000 inhabitants city of Cayambe. The equator passes through its southern flank. The andesitic-dacitic volcano is located on the isolated western edge of the Cordillera Real in the Ecuadorian Andes, east of the Inter-Andean Valley.
The volcano is capped by extensive glaciers, which descend to 4200 m on the eastern Amazonian side. It contains 2 summit lava domes located about 1.5 km apart, the western of which is the highest. Several other lava domes are located on the upper flanks and have been the source of pyroclastic flows down the lower flanks of the volcano.
La Virgen is a prominent young cinder cone on the lower eastern flank, which erupted thick andesitic lava flows that reached 10 km to the east.
There is only one confirmed historic eruption, during 1785-86, but recent studies have shown that the volcano has produced frequent explosive eruptions during the past 4000 years. stratovolcano 5790 m / 18,996 ft Ecuador, 0.03°N / -77.99°W Current status: restless (2 out of 5)

Typical eruption style:explosive Last earthquakes nearbyLatest satellite images  Cayambe volcano news & activity updates:Wed, 7 Dec 2016, 11:26  Current earthquakes (yellow: Sep-Dec 2016; blue: June 2016) under Cayambe (image: IGEPN) The volcano has become restless. Scientists from Ecuador's Institute of Geophysics (IGEPN) recorded an increased number of earthquakes under the volcano a new report shows. The increased seismicity could be (but not must be) a precursor of renewed activity in the medium-term future (weeks, months?). ...moreAn increase of earthquakes began on 5 June this year when a seismic swarm of earthquakes started which totaled more than 2300 events by the end of the month. The quakes occurred concentrated in an area NE of the volcano and were volcano-tectonic in origin, likely caused by a magma intrusion at depth causing pressurization and fracturing of rocks. After the June swarm, the volcano returned to calm again first. New earthquakes started to appear in increased numbers from September and have been continuing. Different from in June, the quakes have been concentrated under the summit area of the volcano and been showing an upward trend in depth.
