Nevado del Ruiz volcano (Colombia): activity increases, new ash emissions

Ash emission from Ruiz on Saturday (19 Sep 2015)
Ash emission from Ruiz on Saturday (19 Sep 2015)
The internal and external activity of the volcano has increased during the past two weeks. Several pulses of tremor were accompanied by ash emissions that produced plumes that rose up to 1.5 2.5 km above the crater, last on 17 and 19 Sep. As fall occurred in areas west of the volcano including Pereira, Dosquebradas, Santa Rosa, Chinchiná, Villamaría, and Manizales.
Weak incandescence, probably due to hot gasses, has been noted from the Arenas crater at night since early Sep. A small explosion on 4 Sep produced incandescent ejecta. At the moment, it is unclear whether fresh magma has been involved in the recent activity or whether it is phreatic in origin, i.e. caused by overheated water circulating in the volcano's upper hydrothermal system.
