Latest Volcanology Stories
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.
Scientists from the Smithsonian and the University of Rhode Island have found unsuspected linkages between the oxidation state of iron in volcanic rocks and variations in the chemistry of the deep Earth.
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.
Volcanism in the Yellowstone region was caused by the defunct pieces of a former mantle plume that were severely deformed. Circulation currents, driven by the movement of tectonic plates at the Cascades subduction zone, also affected the plume.
A plan to build the world’s largest telescope moved one step closer to becoming a reality on Friday, as the Hawaii Board of Land and Natural Resources (BLNR) approved a plan to build the record-breaking instrument at the summit of Mauna Kea volcano.
Last month, Earth science researchers from NASA traveled to Turrialba Volcano near San Jose, Costa Rica. The research team was there to study the chemical environment of the volcano by flying a Dragon Eye unmanned aerial vehicle into the sulfur dioxide plume and over its summit crater.
According to a new study from a team of German researchers, geological forces are stagnating in certain regions because of pressure-induced phase transitions.
One of Iceland’s most active volcanoes, Hekla, has been showing signs of potential activity as of late, prompting National Commissioner of the Icelandic Police to declare an “uncertainty phase” for the snow-capped peak.
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...
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...
