A new study has found that a mixing of two different types of magma is the key to the historic eruptions of Mount Hood, Oregon's tallest mountain, and that eruptions often happen in a relatively short time "“ weeks or months "“ after this mixing occurs. This behavior is somewhat different than that of most other Cascade Range volcanoes, researchers said, including Mount Hood's nearby, more explosive neighbor, Mount St. Helens. The research is being reported this week in Nature...

A team of scientists has returned to the North Atlantic to gather more data on the Icelandic volcanic eruption that took place earlier this year. The researchers are studying whether iron within the vast volcanic ash cloud entered the ocean, causing an extended bloom of tiny organisms known as phytoplankton. The scientists have recorded "enhanced levels" of iron in samples they have collected. The most recent project follows an earlier cruise, which was carried out in the spring. The...

The next Yellowstone eruption could be similar volcanic event Millions of years ago, volcanic eruptions in North America were more explosive and may have significantly affected the environment and the global climate. So scientists report in this week's issue of the journal Nature. The researchers found the remains--deposited in layers of rocks--of eruptions of volcanoes located on North America's northern high plains that spewed massive amounts of sulfate aerosols into the atmosphere 40...

On March 20, Iceland's Eyjafjallajokull volcano woke from its nearly 200-year slumber to change the way the world viewed volcanoes forever. Bringing almost all transatlantic air travel to a halt for the first time in modern history, this volcano reminded humanity of the powers these forces of nature contain "“ and of our relative inability to understand them. Associate Professor Huiming Bao of LSU's Department of Geology & Geophysics has published research in the journal Nature...

Following the eruption of Iceland'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 organized by ESA and EUMETSAT to discuss what has been learned and identify future opportunities for volcanic ash monitoring. The experts included meteorologists, ground-based, air-borne and Earth-observation specialists and modelers. While scientists and researchers shared information about the...

According to experts, an Icelandic volcano neighboring Eyjafjoell, whose eruptions paralyzed Europe's skies last month, could come to life in the near future. "An eruption in the short term is a strong possibility," experts said, referring to Katla, which is much larger than Eyjafjoell, in a report from the University College London (UCL) Institute for Risk and Disaster Reduction. The researchers said that Europe's skies were likely to be hit by further ash cloud shutdowns, following April's...

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. The volcano-chasing researchers argue this adds a further dimension to understanding the detailed nature of volcanic plumes and their effects on air travel. The paper, to be published May 27 in IOP Publishing's Environmental Research Letters, is...

An Internet company from Iceland has capitalized on the volcanic ash plume that led to Europe's biggest aerial shutdown since World War II by turning the crisis into a charity money-maker, its chief executive said on Thursday. The online company, nammi.is, which sells a variety of products from the north Atlantic island, is selling 5.5 ounce jars of the ash from the Eyjafjoell volcano for $29.90 (23.80 euros), with all proceeds going to charity. Since the company began selling the ash 10...

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. Scientists at the GKSS Research Centre Geesthacht managed to reconstruct the spread process and make statements on the concentration of ash particles. As a result of the eruption of the Icelandic volcano Eyjafjallajökul,...

Hualālai
2014-04-10 12:06:55

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

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

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...

Eldfell

Eldfell is an active stratovolcano that is located in Iceland on the island of Heimaey, in the Vestmannaeyjar archipelago. It reaches an elevation of 656 feet and was created during a volcanic eruption on the east side of the island in 1973. Its name means Mountain of Fire in the Icelandic language. Iceland is an area with a high frequency of volcanic activity because it is located on top of the Iceland hotspot and beside the Mid-Atlantic Ridge. So many eruptions occur here that it is thought...

Kīlauea
2014-04-08 12:33:13

Kīlauea is an active shield volcano that is located on the island of Hawaii and is located within Hawaii Volcanoes National Park. This volcano, which reaches an elevation of 4,091 feet, is one of five volcanoes that form the island and it is the most active. It is thought to be between 300,000 and 600,000 years old and is the second youngest of all the Hawaii volcanoes. It was formed when the Pacific tectonic plate moved over the Hawaiian hotspot and like other Hawaiian volcanoes, it began...
