Nevado del Ruiz volcano (Colombia): Red Alert declared

Tue, 10 Apr 2012, 17:03
17:03 PM | BY: T
The Colombian authorities have declared a red alert for the area around the volcano Nevado del Ruiz and warn the population against the feared mud flows (lahars) that are to be expected in an eruption of the volcano. The status of the volcano itself is described as eruption likely in the coming days or weeks.
The reason is a steady increase in seismic activity and gas emissions from the summit crater. In recent days, more and more, usually small earthquakes have been occurring at shallow depths under the volcano, some of them felt. A steam nd gas plume is rising from the crater to 1.5 km and sulfur smell can be noticed in nearby villages and towns.
430 000 inhabitants from the valleys of the Río Chinchina, Manizales and four other rivers have been warned of mud flows and possible floods, which could be triggered especially during heavy rains, even when there is no eruption.
