Parking Lot Lava Flows
2012-08-21 08:07:30

April Flowers for redOrbit.com - Your Universe Online How often have you wished you could safely see a lava flow, like the one that destroyed Pompeii?  Did you ever wish you could see it in Syracuse, New York? Professors, students, visiting volcanologists and passing spectators are now seeing lava flows in a campus parking lot at Syracuse University and have been since January 2010. The Syracuse University Lava Project has created a unique blending of science, art, and education...

Large Pumice Raft Found Floating In The South Pacific
2012-08-14 12:23:30

Brett Smith for redOrbit.com - Your Universe Online Sailors aboard the New Zealand Royal Navy vessel HMNZS Canterbury spotted something odd floating in the ocean a few days ago - a bounty of beauty supplies bobbing in the South Pacific. Pumice is typically used in salons to exfoliate dead skin and the lightweight volcanic rock can often be seen floating in the ocean in large groupings. However, it is rarely seen covering a swath of ocean roughly the size of New Hampshire, a sight one...

Mount Tongariro Erupts In New Zealand
2012-08-07 13:59:40

Lee Rannals for redOrbit.com - Your Universe Online A long-dormant New Zealand volcano erupted on Monday, spewing an ash cloud that disrupted flights and closed highways. The Mount Tongariro volcano located in the middle of the North Island erupted for the first time after lying dormant for more than a century. The last activity the volcano had shown at the site was in 1897, officials said. Witnesses in the area reported seeing "flame-like explosions and a cloud of ash coming from a...

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...

La Garrotxa: Researchers Pinpoint Youngest Volcanic Area In Spain
2012-07-24 12:52:30

Brett Smith for redOrbit.com - Your Universe Online Although volcanic scientists are able to approximate the age of lava flows, determining the exact timing of each of a volcano´s eruptions has proved difficult in the past. A joint research team from the Universitat Autònoma de Barcelona, University of Girona, the Catalan Institute of Human Paleoecology and Social Evolution (IPHES) and other organizations has looked to establish a chronology of eruptions in the...

Australia's Great Barrier Reef Gets A Little Help From Volcanic Eruptions
2012-07-20 06:50:48

redOrbit Staff & Wire Reports - Your Universe Online Have you ever wondered how the Great Barrier Reef came to be? Research conducted by Queensland University of Technology geologist Dr Scott Bryan indicates that volcanic activity in the Southwest Pacific could help to save the Great Barrier Reef, but it could also be what caused it to form in the first place. Dr Bryan and colleagues studied the westward flow or rafting of pumice after volcanic eruptions in Tonga in 2001 and...

Pumice has long been recognized as the original, natural pozzolan–used by the Romans in their impressive 2000+ year-old concrete structures. A landmark study just released by the University of Utah details the performance, longevity and strength advantages of pumice as a concrete-fortifying pozzolan–advantages that are critical for today's high-performance infrastructure and industrial needs. The pumice pozzolan used in the study–HessPozz–was sourced from Hess Pumice...

Smaller Volcanoes Could Cool Climate According To Satellite Research
2012-07-05 16:33:57

A University of Saskatchewan-led international research team has discovered that aerosols from relatively small volcanic eruptions can be boosted into the high atmosphere by weather systems such as monsoons, where they can affect global temperatures. The research appears in the July 6 issue of the journal Science. Adam Bourassa, from the U of S Institute of Space and Atmospheric Studies, led the research. He explains that until now it was thought that a massively energetic eruption was...

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
2014-04-10 10:03:58

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....
