The Colombian volcano Nevado del Ruiz _ located on the border between the departments of Tolima and Caldas _ records a rise in the temperature of the crater and maintains seismic activity that could trigger an eruption.

This volcano has been on orange alert since the end of March the daily average of earthquakes in the colossus went from 50 to 12,000.

“The temperature of the crater has now risen a lot (…) we have temperatures above 700 degrees Celsius,” presidential adviser Luis Fernando Velasco said in an interview with Blue radio. “The magma rose from the south towards the craterhe added to break rocks and cause increased seismic activity.

Velasco explained that at some point the seismicity dropped significantly and what the volcanologists conclude is that the magma was in a magma chamber beneath the crater.

At almost 5,400 meters in height, the volcano Nevado del Ruiz _remembered for the deadly 1985 eruption_ It has been recording small eruptions for a decade, but the Colombian Geological Survey (SGC) states that “there is a chance that a larger eruption will occur in days or weeks.”

“Yesterday we saw a small eruption (…) a combination of very hot ash and some magma trying to come out of the crater,” Velasco said.

About 57,000 people living in the 22 municipalities closest to the volcano are gradually being evacuated., for the resistance of farmers to abandon their crops and animals.
