Hualca Hualca is a 6,025-metre-high (19,767 ft)extinct volcano in theAndes of southern Peru. It is part of the Peruvian segment of theCentral Volcanic Zone, one of severalvolcanic belts in the Andes. It lies about 70 kilometres (43 mi) northwest ofArequipa and is part of a north–south chain that includes the volcanoesAmpato andSabancaya, the last of which has been historically active. Hualca Hualca features a wideamphitheatre-like structure on the northern flank, which was created by a gigantic landslide during thePleistocene. After the collapse, renewed volcanic activity built a new summit and severallava dome complexes within the collapse scar. After the cessation of volcanic activity,glaciers eroded the volcano and formed multiplemoraines. The present-day volcano is covered byglaciers, and during theLast Glacial Maximum, glaciers advanced to low altitudes. There arehot springs andgeysers north of the mountain, and themagma chambers of Sabancaya are located below Hualca Hualca. (Full article...)
