The nearly 300 small earthquakes that have rumbled underneath Yellowstone National Park during the past week seem to have subsided for now, according to data from the Yellowstone Volcano Observatory. The swarm of small earthquakes, the largest in more than two decades, began during the last week of December, and include three quakes that happened last Friday -- a magnitude 3.5 quake at 11:30 a.m., followed by quakes measuring 3.2 and 3.1 at 12:40 p.m. and 1:15 p.m.  Scientists and...

By Jolley, David W Widdowson, Mike; Self, Stephen Abstract: Research from biological and geological sources has highlighted the role of volcanoes in the outgassing of P, and thermal fixation and subsequent atmospheric oxidation of NO^sub x^ in volcanic environments. The impact of these nutrient fluxes on biological systems has been demonstrated on present-day Hawai'i, and here we consider the impact on the plant communities within a large igneous province (LIP). The Miocene Columbia River...

Scientists have exploited crystals from lavas to unravel the records of volcanic eruptions. The team, from Durham University and the University of Leeds, studied crystal formation from a volcano, in Santorini, in Greece, to calculate the timescale between the trigger of volcanic activity and the volcano's eruption. They say the technique can be applied to other volcanoes "“ such as Vesuvius, near Naples, in Italy "“ and will help inform the decisions of civil defense agencies....

Ten Alaskan residents were forced to evacuate the eastern side of Umnak Island after a volcano erupted, sending a cloud of ash 35,000 feet into the air. The eruption of Okmok Volcano, located in Alaska's Aleutian chain, began just before noon and continued through Saturday night, according to the Alaska Volcano Observatory. Residents of a nearby cattle ranch located on the island sought evacuation shortly after eruption, according to the U.S. Coast Guard. Umnak residents were taken to...

WASHINGTON (AP) - Yellowstone National Park, once the site of a giant volcano, has begun swelling up, possibly because molten rock is accumulating beneath the surface, scientists report. But, "there is no evidence of an imminent volcanic eruption," said Robert B. Smith, a professor of geophysics at the University of Utah. Many giant volcanic craters around the world go up and down over decades without erupting, he said. Smith and colleagues report in Friday's issue of the journal Science that...

Researchers at Rensselaer Polytechnic Institute have discovered what likely triggered the eruption of a "supervolcano" that coated much of the western half of the United States with ash fallout 760,000 years ago. Using a new technique developed at Rensselaer, the team determined that there was a massive injection of hot magma underneath the surface of what is now the Long Valley Caldera in California some time within 100 years of the gigantic volcano's eruption. The findings suggest that...

ESA -- Satellite images acquired by ESA's ERS-2 revealed the recently discovered changes in Yellowstone's caldera are the result of molten rock movement 15 kilometres below the Earth's surface, according to a recent study published in Nature. Using Synthetic Aperture Radar Interferometry, InSAR for short, Charles Wicks, Wayne Thatcher and other U.S. Geological Survey (USGS) scientists mapped the changes in the northern rim of the caldera, or crater, and discovered it had risen about 13...

BILLINGS, Mont. -- A newly discovered surface bulge in Yellowstone National Park may be responsible for some unexpected geothermal activity in recent years, according to a study by U.S. Geological Survey scientists. The bulge, about 25 miles across, rose 5 inches from 1997 to 2003 and may have triggered some thermal unrest at Norris Geyser Basin, including a sudden rise in temperatures, new steam vents and the awakening of Steamboat geyser. The findings are part of a paper set to be...

GRANTS PASS, Ore. -- Scientists exploring an emerging undersea volcano near the islands of American Samoa in the South Pacific were so amazed to find eels living in the newly formed lava that they nicknamed the population "Eel City." Hundreds and perhaps thousands of purplish-gray eels about a foot long were swimming around and hiding in the nooks and crevices at the summit of the new volcano at a depth of about 2,000 feet, Craig Young, director of the University of Oregon's Oregon Institute...

Askja
2014-04-09 16:13:20

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...

Lake Toba

Lake Toba, also known as Toba, is a supervolcano and lake that is located in Indonesia on the island of Sumatra. The volcano reaches an elevation of 2,953 feet and the lake stretches across an area of sixty-two miles and is the largest volcanic lake on earth. Toba holds a caldera complex that is comprised of four volcanic craters that overlap each other, the youngest of which is noted as the largest Quaternary caldera. Visible features within the lake include three craters, four cones, and...

Kīlauea

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...
