Latest Volcanology Stories
An archaeologist at the University of Sheffield has found evidence that, contrary to a widely held theory, ancient Syrians made their stone tools locally instead of importing finished tools from Turkey.
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.
A recent study changes the understanding of how the Hawaiian Islands formed. Scientists have determined that it is the eruptions of lava on the surface, extrusion, which grow Hawaiian volcanoes, rather than internal emplacement of magma, as was previously thought.
Using a wide range of scientific techniques, volcanologists have identified the source of the largest eruption in the last 3,700 years, one that is called the "Pompeii of the East.'
A powerful earthquake that struck the southwestern province of Baluchistan, Pakistan Tuesday afternoon, killing hundreds of people, has given rise to a new island off the coast of the country's Gwadar Port.
Obsidian is a naturally occurring volcanic glass with a smooth, hard surface. Obsidian is far sharper than a surgical scalpel when fractured, making it a highly desirable raw material for crafting stone tools for almost all of human history.
A previously unknown channel of slow-moving seismic waves in the Earth’s mantle has been discovered by a team of scientists from the University of California, Berkeley and the University of Maryland.
Researchers led by University of Houston professor William Sager have been able to confirm the existence of the world’s largest single volcano at the bottom of the Pacific Ocean.
Underneath volcanoes, water and fire coexist to generate “hydrothermal” systems. These systems are complex “steam engines” that produce white smoke – fumaroles – sometimes observed at the surface.
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...
