The International Association of Volcanology and Chemistry of the Earth's Interior data sheets (1973) listed Nevado Anallajsi volcano in Bolivia north of Sajama volcano as being active during the past 2000 years, but de Silva and Francis (1990) noted no evidence from analysis of satellite images for Holocene activity in this area. The andesitic-to-dacitic compound volcano overlies an ignimbrite plateau. Younger basaltic lava flows were erupted from a north-flank vent, but Woerner (2006 pers. comm.) indicated there was certainly no Holocene activity at Anallajsi.
