The authorities in Peru say they are evacuating people living near the Ubinas volcano, in the south of the country, because of increased activity.
Officials said it would take three days to move 4,000 residents and their livestock to safer grounds.
Ubinas, Peru’s most active volcano, recently began spewing ash clouds up to 4km (two miles) high.
An eruption of cinder and toxic gases in 2006 killed livestock and forced a similar evacuation.
Last week, the Peruvian government declared a state of emergency in the provinces closest to the volcano to help those most-affected.
Agriculture Minister Juan Benites said the residents and their 30,000 animals, including llamas and alpacas, would be moved to an area 20km (12 miles) away.
The 5,672-metre (18,609-foot) volcano is located about 100 kilometers (60 miles) east of Arequipa, Peru’s second-most populous city.
