Mount St. Helens Magma Levels Rising, But No Eruption Imminent
2014-05-03 05:03:06

redOrbit Staff & Wire Reports - Your Universe Online While magma levels are rising at Mount St. Helens in Washington, there is now evidence that the active stratovolcano will not be erupting any time soon, researchers said during the annual meeting of the Seismological Society of America (SSA) in Anchorage, Alaska on Friday. Lead researcher Seth Moran, a seismologist with the Cascades Volcano Observatory (CVO), explained that a small amount of magma began pooling approximately 2.5...

Pre-eruption Activity In Conduits Affect Volcanic Ejections
2012-07-24 13:53:55

Brett Smith for redOrbit.com - Your Universe Online In addition to being fairly unpredictable, volcanoes can eject a wide range of material, from mile-high plums of black ash to a deadly hail of fist-sized pumice. These ejections travel extremely fast and can reach internal temperatures between 750 to 1,500 degrees Fahrenheit. The prevailing theory has been that the difference in particle size determined when bubbling magma deep below the volcano converts into a rising stream of gas and...

A 3-D model of a volcanic explosion, based on the 1980 eruption of Mount St. Helens in Washington state, may enhance our understanding of how some volcanic explosions occur and help identify of blast zones for potentially dangerous locations, according to an international team of volcanologists. "We took on the modeling of enormously complicated pyroclastic density currents, notably the classic, notorious May 1980 lateral blast that destroyed 500 square kilometers of forested terrain at Mount...

Global warming is not melting away Mount Rainer in Washington state, even if a survey marker at the highest peak suggests it could be, officials say. The Seattle Times reports the aluminum marker pokes nearly 2 feet above the ice cap at the mountain's highest point, giving the appearance part of the ice has melted away. Not so, say experts. The marker, it turns out, was never under ice -- and it wasn't even erected at the summit, said surveyor Larry Signani, who has led teams that measured...

Dwight Crandell, a renowned volcanologist in the U.S. Pacific Northwest, has died of a heart attack at the age of 86, his family said. Crandell died Monday at a hospice in Wheat Ridge, Colo., The Seattle Times reported Friday. When Crandell began working in the Puget Sound lowlands in the 1950s, conventional wisdom held the region had been shaped by glaciers, the Seattle Times reported Friday. Crandell and his colleague, Don Mullineaux, soon observed however that the region's deep layers of...

A controversial new study based on findings from an analysis of records in southern Chile suggests that very large earthquakes can trigger an increase in activity in nearby volcanoes. The researchers noticed that up to four times as many volcanic eruptions occurred during the year following very large earthquakes than did so in other years. They say volcanoes around 300 miles away from an earthquake's epicenter were affected. In the past, scientists had identified only a few cases where...

Until earlier this week, the most recent significant tremor at Mount St. Helens was in October of 2004. On Sunday January 13th, when geologist and private pilot John S. Pallister was flying over the volcano in southwestern Washington he was surprised to spot some steam rising from a fracture in Mount St. Helens' crater. This not only caught Pallister's attention, enough to take some pictures; it also gained the attention of scientists who now think something is moving inside the volcano....

Lassen National Forest is a United States national forest that is located in the state of California. The forest holds 1,070,344 acres and was established in 1905 as Lassen Peak Forest Reserve, which would become Lassen National Forest only a few months later. The forest surrounds Lassen Volcanic National Park, which was established in 1916, and it holds three designated wilderness areas including Thousand Lakes Wilderness and Ishi Wilderness. It is bordered by the Modoc Plateau in the east,...

Lassen Volcanic National Park

Lassen Volcanic National Park is located in the northeastern portion of the state of California in the United States. The park contains 106,452 acres of land that was once inhabited by Native Americans, who knew that the park’s main feature, the Lassen Peak volcano, was full of fire and would erupt at some point. Explorers of European ancestry used this peak in the nineteenth century as a landmark while traveling to Sacramento Valley. One of the guides that accompanied the explorers was...

Crater Lake National Park

Crater Lake National Park is located in the United Sates in southern Oregon and is the fifth established United States national park. The establishment of the park began in 1870, when William Gladstone Steel devoted a large amount of time and money to the area and conducted studies pertaining to the lake and area surrounding it. Steel named many landmarks around Crater Lake including Skell Head and Wizard Island. Steel and his associates pushed Congress to pass the bill establishing Crater...
