Volcanoes are found all over the world, forming primarily at the edges of tectonic plates but can also arise in “hot spots” like the one that created the Hawaiian Islands. In total, there are potentially a few 1,500 active volcanoes on Earth according to the US Geological Survey. From these, 51 are now in continuous […]
Nature conceals within it a multitude of events and magnificent formations that never cease to amaze us. One of them are volcanoes, a geological structure through which magma emerges and is divided into lava and gas from inside the Earth. Volcanoes can have many shapes and release different materials. There are also many submarine volcanoes […]
New research has yielded results that could potentially lead to the development of volcanic eruption warning systems. Previously, lava from “hotspot” volcanoes was thought to be virgin lava, coming from tens of kilometers deep in the mantle. This is not the case, explains Dr Teresa Ubide, a volcanologist at the University of Queensland. “It’s not […]
The volcanoes we see on the Earth’s surface are just the tip of the iceberg. Below the surface, they are fed by a complex network of conduits and reservoirs that bring molten rock, called magma, back to the surface. When the magma erupts, it can generate lava flows that cool down to become volcanic rocks. […]
Each piece begins with a bird’s-eye view of the history and impact of a unique American site, then zooms in to reveal the experience on the ground. In this article, Hawaii-based writer Catherine Toth Fox explores the fiery magic of Hawai’i Volcanoes National Park. © Michael Parkin, Folio Art 35,000 feet: the beginnings of Hawaii […]
Scientists at UC Berkeley have detected previously unknown channels of slow seismic waves in the Earth’s upper mantle, a discovery that helps explain the “hotspot volcanoes” that give rise to island chains such as Hawaii and Tahiti. This 3D view of the first 1,000 kilometers of the Earth’s mantle under the central Pacific shows the […]
Scientists at the University of California at Berkeley have detected previously unknown channels of slow seismic waves in the Earth’s upper mantle, a discovery that helps explain the “hotspot volcanoes” that give rise to chains of islands like than Hawaii and Tahiti. Unlike volcanoes that emerge from collision zones between tectonic plates, hot spot volcanoes […]
