The Peruvian geological agency INGEMMET has published ash fall, lava flow and pyroclastic flow hazard maps for Yucamane, and additional hazard maps are available on its website. According to these the western, eastern and southern flanks could be threatened by lava flows, whereas the older volcanoes protect much of the northern flank. Hazards from pyroclastic flows extend farther, down to the Laguna Aricota lake southwest of the volcano. Hazards from lava flows derive from their ability to bury land and to ignite flammable materials, as well as the possible creation of lava dams on rivers and outburst floods when they break, while the high speed and temperatures of pyroclastic flows threatens people with asphyxiation, burial and burns. More than 9,000 people live in the danger zone.
