Navidad Lonquimay Volcano, Chile Dylan Rothenberg and Caelin Weiss Department of Geology, Colby College

Location Araucanía region of Chile, in Parque Nacional Nalcas. Latitude °S. Longitude °W. Caused by the subduction of the oceanic Nazca plate beneath the South American plate. Earthquake and seismic activity. subduction-probably-accelerating/

Navidad is a cone located on the stratovolcano Lonquimay. Summit of 2,865 meters. 5 volcanic sequences of the Lonquimay volcano. Navidad is a pyroclastic, asymmetrical cone. It now sits about 210 meters high and 700 meters in diameter at the base. Forms and Dimensions

The Navidad Eruption Began on December 25, 1988 following weeks of seismic activity. Stombolian eruptions (the first in 100 years!). Gas emissions, Strombolian eruptions, magmatic degassing, lava flows, vent- clearing emissions. Ended on January 25,

Hazards and Contributions Fatal gas emissions. Far-reaching ashfall impact. Loss of economically valuable livestock and forests. Seismic activity and ashfall- collapse of buildings and infrastructure. Volcano as a tourist attraction.

Basaltic Andesite Andesite Dacite Volcanic Deposits

Rock Types Sedimentary and Igenous Calc-Alkaline Rocks are common.

Navidad Today There are ski slopes nearby No mining at Navidad Geothermal energy is utilized in Chile

Consistently monitored Allows scientists to understand the birth of a volcano (similar to Surtsey) Monitoring Navidad
