A NASA research team is using the latest advances in satellite artificial intelligence to speed up estimates of the heat and volume of lava escaping from an erupting volcano in Iceland.
Volcanic activity more than 200 million years ago may have helped dinosaurs become and remain the world's dominant species by causing the mass extinction of rivals, researchers claim in a recent study.
A volcano in the southern part of Iceland has erupted for the first time in nearly two centuries, forcing hundreds of people to flee their homes and creating concern that a second, more destructive eruption might soon be on the way.
Flowing lava can carve or build paths very much like the riverbeds and canyons etched by water, and this probably explains at least one of the meandering channels on the surface of Mars.
On January 2, Mount Nyamulagira in the Democratic Republic of Congo erupted, spewing lava from its southern flank and raising concerns that the 100 000 people in the town of Sake could be under threat.
Spanish and French researchers have defined the age, location, size and geochemistry of the volcanoes of Gran Canaria during the Holocene, 11,000 years ago, in order to draw up a map of volcanic hazards for the island.
Scientists say buried volcanic rocks along the heavily populated coasts of New York, New Jersey and New England, as well as further south, might be ideal reservoirs to lock away carbon dioxide emitted by power plants and other industrial sources.
The Virunga National Park, home to 200 of the world's 720 mountain gorillas, is in the path of molten hot lava spewing from a volcano that has erupted in the eastern Democratic Republic of Congo.
Mount Nyiragongo is an active stratovolcano that is located in the Democratic Republic of the Congo. This volcano is part of the Virunga Mountains and is located in Virunga National Park. It reaches an elevation of 11,385 feet and has a crater that reaches 1.2 miles in width. This crater typically holds a lava lake that has varied between 2,000 and 10,660 feet in depth. It is not known how long this volcano has been active, but at least 34 eruptions have been recorded since 1882. Mount...
Chaitén is a volcanic caldera that is located in southern Chile that reaches an elevation of 3,681 feet. It is thought that this volcano once held a rhyolite obsidian lava dome that reached 3,156 in height, but this was destroyed after its most recent eruption in 2008. In the past, this volcano has released grey obsidian, which was used by pre-Columbian cultures to make many objects, some of which have been found 250 miles away from the volcano. Chaitén experienced the beginning of a new...
Hualālai is a dormant shield volcano that is located on the island of Hawaii and is one of five volcanoes that form the island. It reaches an elevation of 8,271 feet and is thought to have emerged from the sea about 300,000 years ago, making it the third youngest volcano on the island. Its shape is rough compared to younger volcanoes and it holds three rift zones that are covered with over one hundred cinder cones and spatter cones. Although it does not hold a caldera at its summit, it does...
Kohala is an extinct shield volcano that is located on the island of Hawaii and reaches an elevation of 5,480 feet. It is one of five volcanoes that comprise the island of Hawaii and is thought to be about one million years old, although it only emerged from the sea about 500,000 years ago. Because its last eruption is thought to have occurred about 120,000 years ago, based on studies conducted on hardened lava flows, this volcano is not thought to pose a threat to inhabitants on the island....
Askja is an active stratovolcano that is located in the isolated central highlands in Iceland. It reaches an elevation of 4,974 feet and its name literally means caldera, or box, in the Icelandic language. The area can only be reached during a period of a few months and because it located in the rain shadow of the Vatnajökull glacier to the northeast, it only receives 17.7 inches of rain per year. One of Askja’s smaller craters holds a lake known as Öskjuvatn, which is often frozen over...
