Villarrica Volcano

Villarrica Volcano is part of the Pacific Ring of Fire Region. "Snow-covered Villarrica, one of Chile's most active volcanoes, rises above the lake and town of the same name. The volcano is also known as Rucapillán, a Mapuche word meaning "House of the Pillán". It is the westernmost of three large stratovolcanoes that trend perpendicular to the Andean chain along the Gastre Fault. This alignment crosses the N-S running Liquiñe-Ofqu Fault. Villarrica is one of only four volcanoes worldwide known to have an active lava lake within its crater. Villarrica's lava is basaltic-andesitic but is quite explosive despite this. Two large ignimbrite layers are visible around the volcano; the Licán Ignimbrite and later the Pucón Ignimbrite." (Information provided by wikipedia.org)
