Nevado Del Ruiz , Colombia : An eruption  has forced the closure of a regional airport.

22 MAY 2016. An eruption at the towering Nevado del Ruiz volcano has forced the closure of a regional airport in western Colombia. Colombia’s Geological Service says bursts of ash rose nearly a mile and a half (2,300 meters) above the peak of the volcano at about 5:50 a.m. (6:50 a.m. EDT; 1050 GMT).

A somewhat smaller eruption three hours earlier prompted closure of the La Nubia airport in Manizales, capital of Caldas state. The 17,457-foot (5,321 meter) volcano has been under close observation since a 1985 eruption killed some 25,000 people and demolished the town of Armero. Seismologists say earth tremors indicate movement of magma within the volcano’s system.

The Colombian Geological survey reported a new pulse of tremor occurred today at 05:51 PM (local time), Which is associated with emission of ash and could be seen through our web cameras installed in the area of the volcano, with a maximum height of 2300 meters above the top of the volcano.

It is important to note, that the visual assessment of the emissions of ash is favoured by atmospheric conditions. Even though this type of seismic signals are presented several times during the day, ash emissions associated cannot always be verified visually.
