One team of researchers has uncovered the factors that determine the frequency and magnitude of volcanic activity, while another has identified the triggers for the rare and explosive eruptions experienced by supervolcanoes, according to studies currently appearing in the advanced online edition of the journal Nature Geoscience.
El Salvador's Chaparrastique volcano erupted suddenly on Sunday, causing local authorities to start evacuating thousands of residents within a two-mile radius.
A supervolcano located in Yellowstone National Park is much larger than previously thought, according to research presented at the American Geophysical Union last week.
Geologists from Brigham Young University in Utah have found evidence of a massive supervolcano near the Utah-Nevada border that had a massive eruption around 30 million years ago. It was 5,000 times larger than the Mount St. Helens eruption in 1980.
Mysterious green lightning, seen emerging from an ash cloud in images of a May 2008 volcanic eruption in Chile, is likely more common than we realize.
Japan, which sits on the so-called “Pacific Ring of Fire,” is now home to a new tiny island thanks to a submarine volcanic eruption, which was first reported by the Japanese navy and later confirmed by the country's coast guard.
Researchers have discovered a volcano located beneath roughly one kilometer of ice in western Antarctica, and they believe that the heat it produces could increase the rate of ice loss from one of the region’s primary ice streams.
Several thousand people have been evacuated from the Tanah Karo district of North Sumatra following a volcanic eruption on Mount Sinabung. The volcano, which has emitted several sizeable eruptions over the past few months, is now threatening 10 nearby villages.
Studies of zircon in Yellowstone rocks are giving scientists a whole new look at the life cycle of supervolcanoes.
a new study indicated that bizarre pillars of basalt in Iceland's Skaelingar valley were formed by a very slow lava flow oozing from volcanoes and interacting with water.
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. It is locally known as The Colossus due to large past eruptions. This volcano is located within Irazú Volcano National Park, which holds montane forests...
Rincón de la Vieja is an active complex volcano that is located in northwestern Costa Rica. Its name, meaning The Old Woman's Corner, refers to a legend that says that a woman’s lover was thrown into the volcano by her father, after which she lived on the volcano as a recluse. 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...
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...
Nyamuragira is an active shield volcano that is located in the Democratic Republic of the Congo. This volcano, which is part of the Virunga Mountains, reaches an elevation of 10,033 feet and is the most active volcano in Africa. This volcano is shorter than Nyiragongo, which it shares an area with, and has a low shield profile. It holds a large amount of sulfur dioxide and is blamed for much of the volcano related sulfur dioxide content in the atmosphere. Nyamuragira has erupted over forty...
Imbabura Volcano is an inactive stratovolcano that is located in Ecuador and is part of the southern Ring of Fire and one of many volcanoes created along an arc by the subductions of the Coolyo Plate underneath the South American Plate. This volcano was shaped by strombolian eruptions, which are less violent than plinian eruptions and are characterized by the expulsion of lapilli, lava bombs, and cinders as well as the accumulation of tephra around the point of eruption like a vent....
