Home » Chaitén Volcano Chaitén Volcano: Videos, Pictures, Map, News and Background Chaitén Eruption Chaitén Volcano Summary: On Friday, May 2, 2008, Chaitén Volcano in southeastern Chile erupted for the first time since about 7400 BC. Its initial eruption produced a plume of volcanic ash and steam that rose nearly 17 kilometers high. Winds carried the plume east, over the Andes Mountains and into Argentina. The plume then drifted out over the over the Atlantic Ocean. It was visible on satellite images for hundreds of kilometers over the Atlantic. The volcano shows continued activity and produced additional ash plumes. The town of Chaitén, located about 10 kilometers southwest of the eruption site, was blanketed with ash. About 4,000 people who lived there were evacuated by boat. The town of Futaleufu, with about 1000 residents, was also evacuated. Smaller communities to the southeast such as Chubut and Rio Negro also received heavy ashfalls. The ash plume was so thick in some parts of Argentina that schools, highways and airports were forced to close. Before the eruption, Chaitén was a lava dome within a caldera about 2.5 kilometers wide and 4 kilometers long. The volcano has a history of explosive eruptions, dome building and pyroclastic flows associated with dome collapse. These characteristics, combined with its ability to produce substantial ashfalls, make it a potentially dangerous volcano.
