 The volcano erupted twice in April 2007, once in April 2008 and again in November 2008.Any eruption would affect the small villages around the volcano, mostly Páez, where their inhabitants still have in memory the eruption of the Nevado del Ruiz volcano and the destruction of Armero.On April 18, 2007, the volcano erupted twice causing avalanches into the Paez River; this event caused water levels to rise along the Magdalena River.
