ATHENS – After American and Greek researchers warned in early 2021 that Santorini, home to a now dormant volcano that erupted 3,666 years ago, could explode again, researchers have discovered other inactive volcanoes around the island. A seismic study of the seabed, using sound waves, revealed the discovery buried under volcanic eruption deposits to the […]
The USGS continues to closely monitor volcanoes around the United States, with four now at Orange / Watch elevated due to noted activity on all four of them. The Great Sitkin, Pavlof, Semisopochnoi and Kilauea are the four volcanoes showing signs of trouble. With the exception of Hawaii’s Mauna Loa, which remains yellow / advisory, […]
About 75% of the world’s volcanoes live along the aptly named Ring of Fire. It’s logic. Squeezing a boundary between tectonic plates, the Ring of Fire is an open seam within the planet. But then there’s Hawaii, a chain of volcanic islands right in the middle of the Pacific Plate, far from any border. What […]
The incandescent lava spurting from the Cumbre Vieja volcano continues to wreak havoc on the Spanish island of La Palma, destroying buildings and forcing massive evacuations. The volcanic eruption of La Palma which began on September 19 is one of more than 50 in the world that are marked as “continuous” as of October 12, […]
Photo by B. Carr for USGS When I was younger the volcanoes seemed so cold with all the glowing magma and seemingly slow lava. In adulthood, the idea of a volcanic eruption is terrifying. And if you haven’t heard it, there is one right now. Kīlauea volcano in Hawai’i Volcanoes National Park began to erupt […]
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 […]
Ecological changes following intense volcanic activity during the Carnian rainfall event 230 million years ago paved the way for dinosaurs to become the dominant species.

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. […]
