How was Villarrica formed?
Villarrica is a stratovolcano, and one of the many active volcanoes of the Southern Volcanic Zone of the Chilean Andes. This section of volcanoes has formed in response to the subduction of the Nazca plate beneath the South American plates, and stretches along the backbone of Chile for over a thousand kilometres.
What type of plate boundary is Villarrica volcano on?
Nazca plate
Villarrica Volcano – John Seach Villarrica is one of Chile’s most active volcanoes. The volcano is located in the Andes mountains, and is tectonically associated with east-dipping subduction of the Nazca plate beneath the South American plate.
What type of volcano is Villarrica?
basaltic volcano
Villarrica is an open system basaltic volcano with a long historic record that includes four fatal eruptions. A very large (VEI=5) eruption was dated ca. 1810 BC by the carbon-14 method.
What plate boundary do volcanoes occur on?
convergent plate boundaries
Sometimes, the plates collide with one another or move apart. Volcanoes are most common in these geologically active boundaries. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries.
When was Villarrica volcano formed?
This city was originally founded near the site of present-day Pucón. Villarrica volcano had frequent strombolian eruptions in the second half of the 16th century. Peaks of activity occurred in 1558 and 1562….1971–1972 eruption.

When did Villarrica erupt?
Villarrica, located in Chile, has had historical eruptions dating back to 1558. The current eruption period began in December 2014 and more recently has been characterized by summit crater incandescence, Strombolian explosions, and ash emissions (BGVN 45:09).
Is Villarrica on a plate boundary?
This volcano is located 700 km south of Santiago, the Chilean capital and is in the Andes mountain range. It is on the boundary of the Nazca and South American plates. Villarrica is one of Chile’s most active volcanoes and looms large over the lake and town of the same name.
How are volcanoes formed in convergent boundaries?
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.
Is there volcanic activity in convergent boundaries?
Volcanism occurs at convergent boundaries (subduction zones) and at divergent boundaries (mid-ocean ridges, continental rifts), but not commonly at transform boundaries.
Is Villarrica an active volcano?
Snow-covered Villarrica, one of Chile’s most active volcanoes, rises above the lake and town of the same name. It erupts basaltic lava and is one of the few permanently active volcanoes in the world, with frequent strombolian activity and sometimes a small lava lake present in its summit crater.
How did Puyehue Cordon Caulle form?
Puyehue-Cordón Caulle Volcano started erupting on 24 May 1960. It is possible, that the eruption was triggered by the great earthquake in Chile (magnitude 9.5; the largest measured earthquake in history) on 22 May 1960.
