After a long period of dormancy, Galeras roared back to life in 1988, then erupted again in the early 1990s, 2004, 2006 and earlier this year.
Nearly 8,000 people living in the shadow of southwest Colombia’s Galeras volcano were ordered to evacuate as the mountain erupted twice within 24 hours.
Ash rained down on nearby villages before the eruptive activity slowly subsided.
There were no reports of injuries or significant damage from the mountain’s latest rumblings.
A comparable number of villagers were ordered to evacuate in February after Galeras expelled clouds of ash and steam.
Galeras has erupted frequently since Spanish colonization of the Americas reached the region, with its first historical eruption being recorded on December 7, 1580.
A modern eruption in 1993 killed nine people, including six scientists who had descended into the volcano’s crater to collect gas samples.
