Latest Types of volcanic eruptions Stories
How severely have volcanoes contaminated the atmosphere with sulfur particles in past millennia?
Two of three active Alaskan volcanoes have shown a sizeable increase in activity since first erupting weeks ago, according to the Alaska Volcano Observatory (AVO).
The noble gases get their collective moniker from their tendency toward snobbishness. The six elements in the family, which includes helium and neon, don't normally bond with other elements and they don't dissolve into minerals the way other gases do. But now, geochemists from Brown University have found a mineral structure with which the nobles deign to fraternize. Researchers led by Colin Jackson, a graduate student in geological sciences, have found noble gases to be highly soluble in...
A new collaborative project called FutureVolc is aimed at trying to improve monitoring of Iceland's volcanoes with newly developed up-to-date sensory equipment.
Authorities in Mexico have raised the alert level for towns in two central states and the capital after an increased amount of explosive activity has occurred at Popocatepetl volcano, Mexico’s second highest peak at 17,900 feet.
By using both optical and thermal sensing instruments onboard the Landsat Data Continuity Mission (LDCM) satellite, NASA scientists were able to create a comprehensive image of the Pacific’s Paluweh volcano in mid-eruption.
One of the Philippines most active volcanoes roared to life early Tuesday sending a cloud of ash and rocks into the morning sky. Mount Mayon, which sits about 206 miles southeast of the capital of Manila, killed at least four people and injured several others during the brief eruption.
The Cleveland Volcano, which sits at the western end of Chuginadak Island (part of the Aleutian Islands), erupted in at least three low-level explosions that were not severe enough to cause significant threats to air travel, but did force federal aviation authorities to divert some flights farther north of the volcano as a precaution.
Detailed mapping and sampling of the partially eroded Kima' Kho tuya in northern British Columbia, Canada shows that the ancient regional ice sheet through which the volcano erupted was twice as thick as previously estimated
Recognizing well-established patterns of pre-eruption unrest in monitoring data is vital in volcanic eruption forecasting. To develop better monitoring procedures, however, understanding volcanic eruptions that deviate from these patterns is crucial as well.
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....
