BTN News: The Colombian Geological Service reported an unusual seismic activity near the Laguna de La Cocha in Nariño, Colombia. Since Thursday, August 15th, this region, known for the Guamuez-Sibundoy volcanic field, has experienced a spike in seismic events. This volcanic area is distinguished by its unique characteristics compared to other well-known Colombian volcanoes like Nevado del Ruiz or Galeras. According to John Makario Londoño, Director of Geo-threats at the Colombian Geological Service, the Guamuez-Sibundoy field comprises numerous volcanoes, each of which has erupted only once, exhibiting different behavior from the more active and familiar volcanoes.
In recent days, this region has been affected by significant seismic activity due to the presence of important geological faults that intersect the area. The possibility of an interaction between these faults and the volcanic field is being studied, though more time is needed to determine the exact nature of this phenomenon. The situation is under close monitoring, with scientists awaiting further developments to gain a clearer understanding of what is happening beneath the earth’s surface.
From August 15th, the area has recorded a total of 439 seismic events, with one earthquake reaching a magnitude of 3.4, and seven others exceeding a magnitude of 2. This is an unusual concentration of seismic activity compared to previous years when fewer earthquakes were recorded in the same region. The Colombian Geological Service has reassured the public that the Guamuez-Sibundoy volcanic field remains at a green alert level, indicating that the volcanoes are currently in a state of rest.
This surge in seismic activity has drawn attention due to its sudden intensity and the unique nature of the Guamuez-Sibundoy volcanic field. The field’s volcanoes are not like the more predictable, frequently erupting ones that Colombians are used to. Instead, each volcano here has a history of erupting only once, making the current situation particularly intriguing and somewhat unpredictable.
Experts emphasize the importance of continuous monitoring and communication with the public, especially in regions like Nariño, where volcanic and seismic activities can have significant impacts on local communities. The authorities are committed to keeping the population informed about any changes in the situation and are closely observing the seismic patterns to anticipate any potential risks.
As this story unfolds, it highlights the complexities of volcanic systems in Colombia and the challenges faced by scientists in predicting volcanic behavior in less active, but still potentially hazardous, fields like Guamuez-Sibundoy. The situation serves as a reminder of the dynamic nature of the earth’s geology, particularly in regions crisscrossed by geological faults and home to dormant volcanoes that could awaken under the right conditions.
In conclusion, while the Guamuez-Sibundoy volcanic field remains at a green alert level, indicating no immediate danger, the unusual seismic activity observed in recent days warrants close observation and further study. The Colombian Geological Service will continue to monitor the situation and provide updates as more information becomes available. Residents in the affected areas are encouraged to stay informed and follow any guidance from authorities to ensure their safety in the event of any significant changes.
