The Volcanological and Seismological Observatory of Manizales reported two moderate earthquakes after a swarm of minor quakes in the Nevado del Ruiz volcano.
The quakes are related to rock fracturing and demonstrate a significant increase in the volcanic activity of the volcano.
The earthquake swarm started at around 5pm on April 29, 2016, before two moderate tremors (both M3.4 on Richter’s scale) occurred at the 8:26 and 8:46 pm on April 29, 2016.
The two stronger quakes were located in the northeastern sector of the volcanic structure at a depth of 3.78 kilometers.
Ash falls has also been reported in Murillo, a small city near the Nevado del Ruiz volcano, which shows increased seismic activity.
Officials say, the Nevado del Ruiz volcano is emitting ash since already 17 months, but due to the particular weather conditions it has started falling around.
Probably one of the next eruption!
