2012-11-22 12:18:51

Lawrence LeBlond for redOrbit.com - Your Universe Online After more than a century of dormancy, a New Zealand volcano has erupted a second time in four months, sending a column of ash more than a mile into the sky and forcing school children and tourists to flee from the area, according to local reports. The Mount Tongariro volcano erupted at 1:25 p.m. local time (00:25 GMT) on November 21, and spouted off for about five minutes before settling back down. While scientists said there...

redOrbit Staff & Wire Reports - Your Universe Online At the time of his death, it appeared that Lonesome George was the last member of his species, but new research suggests that his breed of giant tortoises might live on after all. According to Jennifer Viegas of Discovery News, experts at Yale University have reportedly discovered DNA evidence suggesting that members of the species Chelonoidis abingdoni could still exist. Those researchers collected genetic material from more...

Volcanic Eruptions Predicted With Satellite Imagery
2012-11-05 14:28:53

Brett Smith for redOrbit.com - Your Universe Online In a new report published in the journal Geophysical Research Letters, two scientists showed they may now be able to detect signs of an impending volcanic eruption by analyzing satellite imagery. Using Interferometric Synthetic Aperture Radar (InSAR) over the active volcanoes in Indonesia's west Sunda arc, the vulcanologists from University of Miami uncovered evidence that showed the ℠inflation´ of several volcanoes prior to...

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...

Volcanic Eruptions Driven By Bubble Growth
2012-10-17 04:36:06

Alan McStravick for redOrbit.com - Your Universe Online From Pompeii to Mount St. Helens, we humans have watched in awe, and sometimes horror, the magnificence of volcanic eruptions. As detailed in a great article earlier this month by redOrbit´s own Lee Rannals, monogenetic volcanoes, volcanoes erupting due to the combination of water and magma, are driven by a rapid expansion of gas bubbles that form as the water, previously trapped in molten rock, rises beneath the volcano....

Trigger For Explosive Volcanic Eruptions Identified
2012-10-13 09:27:11

Lee Rannals for redOrbit.com — Your Universe Online Scientists have identified a trigger for the largest explosive volcanic eruptions on Earth, according to a report published in the journal Scientific Reports. University of Southampton researchers investigated crystal cumulate nodules and their trapped magma to see what caused eruptions at the Las Cañadas volcanic caldera on Tenerife, in the Canary Islands. This volcano has generated at least eight major...

Indonesia Volcano Lets Out Roar Over Weekend
2012-10-08 14:49:15

Lee Rannals for redOrbit.com — Your Universe Online An active Indonesian volcano erupted once again, spewing out clouds of ash and alarming residents as far as three miles away. Mount Lokon, a 5,214-feet volcano on northeast Sulawesi island, has been very active recently, and on Sunday it added another eruption to its track record. Since its biggest eruption in July 2011, when over 5,200 people were evacuated, Mount Lokon has erupted and spewed clouds of ash about 600 times....

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...

Jabal al-Tair Island
2014-04-10 11:56:15

Jabal al-Tair Island, known by many other names including Tair Island and Jebel Teir, is a volcanic island that is located in the Red Sea and is under the jurisdiction of Yemen. It reaches an elevation of 801 feet and is about 1.9 miles in length. The island is comprised of Jabal al-Tair, a stratovolcano that was considered extinct in 1982, although it erupted in 2007. In 1900, the British Admiralty described the volcano as having a steep, conical shape, making it a good landmark for ships...

Mauna Kea
2014-04-10 11:49:35

Mauna Kea is a dormant shield volcano that is located on the island of Hawaii and reaches an elevation of 13,803 feet. It is one of five volcanoes that comprise the island and is thought to be about one million years old. Mauna Kea, like all Hawaiian volcanoes, was created when the Pacific tectonic plate passed over a volcanic hotspot. The Hawaiian volcanoes, which extend over an area known as the Hawaiian Ridge – Emperor Seamount chain, have been well studied, but it is not known how the...

Zubair Group
2014-04-10 10:08:46

Zubair Group, also known as Zubayr Group or Al Zubair Group, is a chain of volcanic islands belonging to Yemen that are located on top of a shield volcano in the Red Sea. Zubair Group The largest island, known as Zubair, is among the youngest islands, which also include Saba, Saddle, and Haycock. The shield volcano underneath the islands began a period of eruptions and eventually quieted down, followed by a period of explosive and effusive eruptions that formed the islands that are present...

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....
