Calbuco, a 2,000m (6,572ft) volcano in Chile, has erupted twice in the past day, sending emergency services (and photographers) into overdrive. The eruption has prompted the evacuation of roughly 4,000 citizens from nearby cities and villages, and the Argentinian authorities have warned their citizens about volcanic ash as well.

The volcano overlooks the cities of Puerto Montt and Puerto Varas, which have a combined population of roughly 250,000 people. It last erupted in 1972, so authorities were somewhat surprised by the outburst. Calbuco is a stratovolcano (also known as a composite volcano), and these are best known for having explosive eruptions – the infamous Krakatoa, Vesuvius and Mt. St. Helens volcanoes are all stratovolcanoes. We can only hope that Calbuco does not decide to blow its top as well.

With the authorities on the ground doing their jobs to keep people safe, we can turn our attention to the photographers that have been having a field day with the eruption. Stunning photos of smoke columns painted red by lava and enormous ash plumes laced with lightning have been pouring out of the area. Check out some of the photos and footage below!
