Hawaiian Volcanoes Compete For The Same Magma Supply
2012-10-24 06:12:27

April Flowers for redOrbit.com - Your Universe Online About 50 miles underground, there is a deep connection between two of Earth's most notable volcanoes, Hawaii's Mauna Loa and Kilauea, that could explain some of their enigmatic behavior. A new study, led by Rice University, is the first to model paired volcano interactions. It explains how a link in Earth's upper mantle could account for the competition between Kiluea and Mauna Loa for the same deep magma supply. The results of this...

A fissure on Kilauea Volcano on the Big Island of Hawaii sent lava spewing more than 60 feet into the air recently, and scientists continued to monitor the activity closely. Park rangers said that no homes were threatened in the latest blast and also cautioned campers and visitors to keep their distance while it continues to act up. Kilauea has been constantly erupting for the past 28 years. But according to geologist Janet Babb of the US Geological Survey (USGS), this weekend's activity...

Eruptions at a Hawaiian volcano have forced officials to close off part of a national park to visitors while geologists monitor eruptions and other seismic activity in the area. According to the Daily Mail, US Geological Survey (USGS) scientists working at the Hawaiian Volcano Observatory (HVO) have reported "a fountain of fire" at the Kilauea Volcano. The volcano in question is located near Napau Crater in Hawaii County, and began erupting Saturday afternoon. "That event was nearly...

Hawaii's Kilauea volcano seems to be active again, with molten lava moving around 300 feet under the crater's floor. The growth of the Halemaumau crater corroborates scientists' certainty that the lava is near the summit, said Janet Babb, a geologist and spokeswoman at the U.S. Geological Survey's Hawaiian Volcano Observatory. Park rangers have started allowing the overlook at the Jaggar Museum to stay open later in the evening to have capacity for the larger numbers of visitors to see the...

From June 17-19th 2007, Kilauea experienced a new dike intrusion, where magma rapidly moved from a storage reservoir beneath the summit into the east rift zone and extended the rift zone by as much as 1 meter. Researchers from the University of Hawaii at Manoa (UHM), Scripps Institution of Oceanography at UC San Diego, and the U.S. Geological Survey (USGS) Hawaiian Volcano Observatory have now discovered that the 2007 dike intrusion was not the only action going on: the dike also triggered a...

Hawaii's Big Island is rattled by thousands of minor earthquakes a year, mainly from volcanic eruptions. But the strongest and most destructive types - like Sunday's magnitude-6.7 that caused blackouts and landslides - are rare and are caused not by eruptions, but by the buildup of stress deep in the crust as volcanoes grow and spread, experts say. The Big Island is the youngest in a ring of volcanoes stretching some 3,500 miles across the Pacific Ocean. As new island volcanoes form and old...

HONOLULU (AP) - Earthquakes at Mauna Loa sharply declined during 2005, leading geophysicists to believe the world's largest volcano is less likely to erupt than they earlier thought. Scientists recorded about 2,000 earthquakes at Mauna Loa on the Big Island in 2004. Many of the temblors were deep, long-period events suggesting magma was rising. But the seismic activity backed off at the beginning of last year. Last January, scientists recorded 34 earthquakes, a sharp decline from 365 the...

VOLCANO, Hawaii (AP) -- The Kilauea volcano, one of Hawaii's most popular tourist attractions, is also by far the state's worst air polluter. Researchers now are trying to determine if that also makes it one of the state's biggest health risks. Since it began erupting on Jan. 3, 1983, the volcano has been sending an average of 1,000 metric tons of sulfur dioxide into the atmosphere each day, according to the Hawaii chapter of the American Lung Association. This is 6,000 times the amount...

VOLCANO, Hawaii (AP) -- Lava from Kilauea volcano began dropping into the ocean at two new points this week, treating visitors to Hawaii Volcanoes National Park to a fiery show. The lava began flowing into the Pacific on Monday at one spot that is about a mile and a half from a park ranger station. The second spot is on the far side of the park near the former town of Kalapana, which was covered by lava in 1990. As lava hits the ocean, it can create crowd-pleasing explosions and fantastic...

Hawaiʻi Volcanoes National Park
2013-04-17 22:28:14

Hawaiʻi Volcanoes National Park is located in the United States on the island of Hawaiʻi. The park contains 323,431 acres of land, of which half is designated as Hawaii Volcanoes Wilderness, and the distinctive Mauna Loa and Kīlauea volcanoes. Mauna Loa is the world’s largest volcano and Kīlauea is among the world’s most active. The first American visitor to the park was Asa Thurston and the first English visitor was a missionary named William Ellis, both of whom traveled to the...
