A University of Utah seismologist analyzed seismic waves that bombarded Earth's core, and believes he got a look at the earliest roots of Earth's most cataclysmic kind of volcanic eruption. But don't worry. He says it won't happen for perhaps 200 million years.
Irazú Volcano, known as Volcán Irazú in Spanish, is an active stratovolcano that is located in Costa Rica. The origin of the volcano’s name is unknown, but it is thought to be a variant of the word Iztarú, which is the name of a village that was near the volcano, or a mixture of the words ara, meaning point, and tzu, meaning thunder.

This volcano reaches 6,286 feet in elevation and is the tallest volcano in Rincón de la Vieja Volcano National Park. Visitors were once permitted to climb up to the crater, but a recent eruption caused this area to...
Chimborazo is an inactive stratovolcano that is located in Ecuador and is part of the Cordillera Occidental range of the Andes. This volcano reaches an elevation of 20,564 feet and although it is not the tallest mountain measured above sea level, its proximity to the equator makes its summit the farthest away from the center of the earth. The origin of its name is unknown, but it could have received its name from several words in the Quichua or Quechua language or from the Cayapa language....
Cotopaxi is an active stratovolcano that is located in Ecuador and is part of the Pacific Ring of Fire. This volcano, reaching an elevation of 19,347 feet above sea level, is the second tallest volcano in Ecuador and one of the tallest active volcanoes in the world. The origin of its name is unknown, but some sources say that it means Neck of the Moon in the language of the indigenous people and it has been considered sacred in their culture. Cotopaxi is shaped like a cone that is almost...
Mount Hudson, also known as Volcán Hudson, is an active stratovolcano that is located in southern Chile, named after 9th-century Chilean Navy hydrographer Francisco Hudson. Its summit, which is covered in glaciers, holds a caldera that was created from a large eruption that occurred in 4750 BCE or 1890 BCE. Based on evidence found at the Los Toldos archaeological site, it is thought that the early eruption destroyed most settlements in the area at that time. Modern eruptions occurred in...
