It sounds like such a simple question: how many volcanoes are there on the Earth. But it’s actually very complicated, and the true answer is that scientists just don’t know. Some volcanoes are completely unknown, hidden beneath the ocean. Other volcanoes haven’teruptedin a long time, an...
Turns out Venus is even more of a hellscape than we imagined. The planet may be chock full of active volcanoes.
For example, Klyuchevskoy and Lokon are listed with two eruptions each, so the number of volcanoes with confirmed eruptions would only be 42 according to the above list. However, we quickly realize that some of the most known active volcanoes are missing: Kilauea, Stromboli, Yasur and many ...
Worlds on Fire: Volcanoes on the Earth, the Moon, Mars, Venus and Io Anyone who has ever thought that volcanoes and volcanism were restricted to the planet Earth should open any page of this book to discover that some of the most spectacular explosions in the Solar System are not occurring...
ash and other "pyroclastic" materials accumulated over many eruptions and emissions. In sharp contrast, a shield volcano — such as enormous Mauna Loa and Mauna Kea in Hawaii — assumes a much gentler slope from easily flowing basaltic lava. Volcanoes may also assume the shape of cinder cones ...
Volcanoes are typically found near the borders of tectonic plates, born from clashes between those giant slabs of rock as they drift on top of the mantle layer between Earth’s core and crust. Classic examples of such volcanoes are those that make up the so-called Ring of Fire on the Pa...
Some volcanoes erupt with an explosive spray of lava and ash, whereas some, like the active volcano in Hawaii, the lava flows out the opening. It all depends on the shape and the opening! The more confined the space, the more explosive the eruption. Our sandbox volcano is an excellent ex...
Hawaii Volcanoes National Park is located on “the big island”, Hawaii. It was created in 1916. The park features two active volcanoes, one of which, Mauna Loa, is the world’s largest shield volcano. The other, Kilauea, is one of the world’s most active volcanoes. ...
Immersive virtual reality can potentially open up interesting geological sites to students, academics and others who may not have had the opportunity to visit such sites previously. We study how users perceive the usefulness of an immersive virtual reality approach applied to Earth Sciences teaching an...
The stunning city of Petra in Jordan was built by the Nabataeans with staggering sums from the luxury trade. Now the discovery of a faraway submerged altar temple shows the extent of its reach.
