seismic activity of the volcano Nevado del Ruiz It decreased in the last hours, as did the column of gases coming out of its crater, which does not imply a change in the orange alert level that was declared on March 31, the Geological Service reported this Sunday. Colombian (SGC).
“Yesterday, April 8, 1,400 events were recorded, reaching a maximum magnitude of 2.4 ML (local magnitude) corresponding to the earthquake at 10:19 a.m.”, pointed out the SGC in its daily bulletin on the seismic activity of the volcano.

According to the information, until 9:00 local time (14:00 GMT) this Sunday “around 180 events have been recorded”, an amount much lower than the more than 12,000 earthquakes that it had ten days ago.
“This marked decrease in seismicity has coincided with a decrease in the size and thickness of the gas column, particularly in the water vapor content during the early morning and so far this morning.”, the bulletin added.
Due to this lower activity, the SGC indicated that starting tomorrowThe number of daily earthquakes will not be reported again, since it is no longer as relevant a parameter in the development of this activity as it was at the beginning”.
However, the agency adds, parameters such as the location of the earthquakes with respect to the crater and their depth take on greater importance in this type of movement.
“The maximum height of the column of gases and/or ash observed was 1,700 meters, measured from the top of the volcano with a dispersion direction that oscillated between east and southeast.” and the emission of sulfur dioxide into the atmosphere remains at levels similar to those observed in previous days.

He Geological Service has warned that the activity of the volcano can fluctuate and at times decrease compared to previous days, without this meaning that it has returned to a lower level of activity, for which the orange alert will be maintained.
an eruption of Nevado del Ruizfollowed by the melting of its glaciers, caused an avalanche on November 13, 1985 that devastated the town of Gunsmithin the department of tolimawhere more than 23,000 of its 25,000 inhabitants died in the largest natural catastrophe in Colombia.
