Millions of years ago, volcanic eruptions in North America were more explosive and may have significantly affected the environment and the global climate.
On March 20, Iceland's Eyjafjallajokull volcano woke from its nearly 200-year slumber to change the way the world viewed volcanoes forever.
(All amounts in US dollars unless otherwise stated) VANCOUVER, June 14 /PRNewswire-FirstCall/ - Magma Energy Corp. (TSX: MXY) is pleased to provide an update on its activities at three of its Nevada projects.
Following the eruption of Icelandâ€™s Eyjafjallajoekull volcano that spewed huge amounts of ash and grounded numerous flights, more than 50 experts from around the world gathered at a workshop to discuss what has been learned and identify future opportunities for volcanic ash monitoring.
According to experts, an Icelandic volcano neighboring Eyjafjoell, whose eruptions paralyzed Europe's skies last month, could come to life in the near future.
In the first peer-reviewed scientific paper to be published about the Icelandic volcano since its eruption in April 2010, UK researchers write that the ash plume which hovered over Scotland carried a significant and self-renewing electric charge.
An Internet company from Iceland has capitalized on the volcanic ash plume that led to Europeâ€™s biggest aerial shutdown since World War II by turning the crisis into a charity money-maker.
Some German airlines leveled their criticism against the forecasts of the Volcanic Ash Advisory Centre (VAAC) in London on the spread of the ash cloud over Europe, as these forecasts did not provide any precise information on the ash concentration in the atmosphere.
Although the Eyjafjoell volcano in Iceland has continued to erupt since April 14, it is spewing far less ash than last week when it caused new interruptions to flights throughout Europe.
Scientists have used quantum mechanics to reveal that the most common mineral on Earth is relatively uncommon deep within the planet.
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...
