He Colombian Geological Service (SGC) delivered a new bulletin about the activity that has been presenting the Nevado del Ruiz volcano.
For that occasion, the entity was in charge of clarifying that the registered activity is related to the rock fracturing inside the volcanoat a depth of between two and four kilometers and at a distance of between two and six kilometers from the crater.
(Tourism at Easter increased slightly, according to the Government).
The SGC stated that, last Tuesday, “the maximum magnitude was 1.3 corresponding to the earthquake at 05:03 am, located 4 km southwest of the crater and about 3 km deep from the top of the volcano”.
In addition, the SGC reported that the seismic activity that has occurred throughout the week is mainly due to to the movement of fluids within the conduits of the volcano, which is associated with the emission of ash. It was measured that the maximum height reached by the column of gases emitted by Nevado del Ruíz was 2.5 kilometers measured from the top of the volcano.
(Activity of the Nevado del Ruiz volcano changed: it has new magma).
Similarly, the geological entity attached to the Ministry of Mines and Energy reported several reports of ash fall in the municipalities of villamaria and Finlandin the departments of Caldas and Quindiorespectively.
activity has not ceased
The SGC was in charge of clarifying that the volcano’s activity continues to be “very unstable”, adding that despite the fact that there was a decrease in rock fracturing, there are other parameters that are proof of the volcano’s activity, to the point that the aforementioned factor It is no longer the main indicator of snowfall behavior, but it is the activity of fluids in the volcanic conduits and various thermal anomalies in the vicinity of the crater.
(Situation in the Nevado del Ruiz “is increasingly complex”: says SGC).
The entity reaffirmed that the Orange alert due to the instability of volcanic activity, adding that Despite the fact that the Nevado del Ruiz presented seismic decreases in the previous days, it is not significant that the activity continues to fall.
“To change the level and return to the yellow level, a prudential time is required where trends and patterns can be observed that allow us to infer the possible decrease in activity, which is why it is warned that the level of activity of the Nevado del Ruiz volcano will remain at a level orange for several weeks”, explained the SGC in the bulletin.
(Nevado del Ruiz: why could you change your alert from orange to red?).
Finally, the agency explained that the red alert will only be activated “in case there is an acceleration of the processes that suggest an imminent eruption or that the eruption itself occurs”.
