The river's new course shown in the center of the image. North is to the left.Following the eruption of the Chaitén volcano, a lahar destroyed much of the town of Chaitén.
The town was evacuated in May 2008 when the Chaitén volcano erupted for the first time in more than 9,000 years.[3][4] The eruption, which commenced May 2, became more violent on May 5,[5] throwing up a high plume of ash and sulfurous steam that rose to 19 miles (31 km), from which ashfall drifted across Patagonia and over the Atlantic Ocean.[6] During 2005 small earthquakes occurred below Chaitén and the nearby Liquiñe-Ofqui Fault Zone.[7]
The town was completely flooded on May 12, 2008, after a lahar caused the banks of the Blanco River to overflow about 200 m (660 ft) on each side.[8] Over the subsequent weeks, the river excavated a new course through Chaitén, completely destroying a significant part of it by July 2008. This process is still ongoing; it is unclear how extensive the damage will ultimately be. Some defensive work has been undertaken by the government, but they ultimately decided to abandon the town, relocating and compensating all residents.[9] The provincial capital was provisionally moved to Futaleufú after the eruption breakout, but the capital shift was later on declared permanent. The future of the town has become a matter of political controversy in Chile.
Reconstruction of Chaiténedit
On February 25, 2009, the government announced plans to rebuild Chaitén 10 km (6.2 mi) north of its current location in a coastal place known as Santa Bárbara or "Fandango Norte".[10] On March 3, 2009, construction work on the new town's administrative facilities started.[11]
On April 9, 2011, president Sebastián Piñera announced a program to rebuild the town on its existing northern area, reversing plans by the previous administration to move the town to a different location farther north.[12]
