  • Mining Volcanoes: Diamonds, Copper and Hot Water

    2019-4-17  Active volcanoes are found in quite specific geological settings in the Earth’s crust. These largely relate to the presence of tectonic plate boundaries, where crust is either newly formed or else destroyed, can cause magma bodies to form at depth which can feed overlying volcanoes at the surface. Through geological time, by using

  • We Just Got Even More Evidence That Venus Has

    2 天前  Well, we just got some of the best evidence yet. Venus has plenty of volcanic features on its surface - wide volcanic plains, domes and coronae, mountainous shield volcanoes. Researchers led by geophysicist Anna Gülcher of ETH Zürich in Switzerland used simulations to figure out how volcanic coronae form and grow, and determined that the features observed on Venus must be quite young.

    The volcanoes that have erupted and since stayed quiet, are termed as dormant volcanoes. Dormant volcanoes are inactive volcanoes which have become incapable of a volcanic eruption due to lack of contact with the magma underneath them. An active volcano is defined as any volcano that has erupted at least once in the last 600 years.
