The Geophysical Institute detected a seismic anomaly under the Cayambe volcano.

The Geophysical Institute (IG) and the National Polytechnic School of Ecuador reported on June 22 that since the beginning of the month, was detected a seismic anomaly under the Cayambe volcano, about 60 kilometers northeast of Quito, the most intense disruption since 1995.
Although this anomaly “tends to decrease,” remains on the base level set in 1995 to the volcano, said the IG in a special report published on June 22 . They underlined that seismic events detected in Cayambe are related to the breaking of rocks inside and small tremors are located in the extreme northeast of the volcano.

Earthquakes are distal volcano-tectonic type and occur in areas of geological faults near volcanoes, which, in the case of Cayambe, correspond to Chingual fault system, which passes through the region, said the IG. However, the institute said the global positioning system measurements (GPS) and inclinometers located on the volcano “show no signs of deformation of the volcano” that could “indicate the presence of a magmatic intrusion.”

“The Geophysical Institute continues to monitor the volcano and any change of activity be notified,” says the text.

Cayambe is an active volcano located in the northern part of the Royal Andes of Ecuador, at whose feet lies the town of the same name with a population of 20 000 inhabitants.
The summit of this volcano is formed by domes, the westernmost of those is at a maximum height of 5790 meters and has an ice cap that starts at 4800 meters, with an approximate area of 22 square kilometers, the report of IG said . It also notes that over the past 4000 years, were identified at least 21 eruptive events, the last of which is presented between 1785 and 1786 according to historical and geological studies.
“Statistically Cayambe volcano has a recurrence period of about 200 years between eruptions,” says the study.
