Increases seismic activity in a volcanic complex on the border of Ecuador and Colombia

Increases seismic activity in a volcanic complex on the border of Ecuador and Colombia



The Geophysical Institute of the National Polytechnic School of Ecuador reported on Saturday an increase in seismic activity in the Chiles-Cerro Negro volcanic complex, located in the border area with Colombia.

In its Facebook profile, the Institute indicated that since Friday, the monitoring network of the mentioned Volcanic Complex detects "a new increase in seismic activity".

Until Saturday morning, about 800 events were counted, and the largest earthquake reached a magnitude of 3.

"There are no reports that the earthquakes have been felt," the Geophysical Institute said before recalling that it maintains its surveillance 24 hours a day, so he said that "any change will be reported in a timely manner."

The joint network of the Geophysical Institute of Ecuador and the Observatory Vulcanológico de Pasto, in Colombia, maintain a permanent surveillance of the seismic and volcanic situation in the area.

In 2014, when an earthquake of magnitude 5.9 on the Richter scale was recorded, the authorities of Ecuador decreed the orange alert situation in the areas surrounding the Chiles and Cerro Negro volcanoes, on the border with Colombia.

The National Secretariat for Risk Management then issued a warning statement in the "areas considered high risk in the province of Carchi for the activity of volcanoes."

The measure ordered that the Emergency Operations Committees of the area "remain alert and operational" before "any negative situation that could be generated by the natural phenomenon."

The snow-capped Chiles volcano, which has no glaciers, is located in the Pastos knot and together with the Cerro Negro de Mayasquer volcano, they are part of the border between Colombia and Ecuador.

The elevation is 38 kilometers from the city of Tulcán, capital of the Ecuadorian province of Carchi (Andes), bordering Colombia.

The Chiles, active stratum-volcano type, extends over 7,351 square meters of the strip that integrates the volcanic corridor along the Cumbal and Azufral.

The volcano, located in the páramos of Tufiño in the border with Colombia, presents / displays an irregular relief with rock formations rather high product of the different volcanic eruptions, according to the Government of The Carchi.

Surrounded by frailejones (plant of the family Asteraceae, native of Colombia, Venezuela and Ecuador) and pajonales adorned with exotic multicolored flowers such as pink urco (exotic Andean flower), the area of ​​Chiles is a shelter for numerous condors, turtledoves, partridges and hawks.

The fog that occurs in this place is quite thick, especially in the morning and afternoon due to temperature changes.
