Ash rains down on nearby villages.
Colombia warned Tuesday of a possible eruption of the Nevado del Ruiz volcano after it began rumbling and spewing gas, dumping ash onto cities and nearby towns.
The government’s geology and mining oversight institute raised the warning level to orange from yellow – the second time this year the warning level has been set at orange – which means an eruption is possible in days or weeks.
Civil aviation authorities suspended operations at the Manizales, Armenia, Cartago and Pereira airports due to visibility problems and concerns over aircraft engines getting clogged.
In 1985, an eruption unleashed a cascade of debris down the volcano’s eastern slope that wiped the town of Armero off the map and killed 25,000 people.
