Mud Volcano Island Rises From Sea After Pakistani Earthquake
2013-09-26 14:22:20

Lawrence LeBlond for redOrbit.com - Your Universe Online A powerful earthquake that struck the southwestern province of Baluchistan, Pakistan Tuesday afternoon, killing hundreds of people, has given rise to a new island off the coast of the country's Gwadar Port. The island, which rises to more than 60 feet above sea level, received its first visits yesterday from local residents wanting to explore the small muddy, rocky landmass. As locals surveyed the new islet, it became evident that...

Study Finds Human Activity Affects Vertical Structure Of Atmospheric Temperature
2013-09-17 13:05:39

Lawrence Livermore National Laboratory Human influences have directly impacted the latitude/altitude pattern of atmospheric temperature. That is the conclusion of a new report by scientists from Lawrence Livermore National Laboratory and six other scientific institutions. The research compares multiple satellite records of atmospheric temperature change with results from a large, multi-model archive of simulations. "Human activity has very different effects on the temperature of the...

Newly Discovered Seismic Waves Reveal Earth's Volcanic Hotspots
2013-09-06 08:40:14

April Flowers for redOrbit.com - Your Universe Online A previously unknown channel of slow-moving seismic waves in the Earth’s mantle has been discovered by a team of scientists from the University of California, Berkeley and the University of Maryland. These waves help to explain "hotspot volcanoes" that give birth to island chains such as Hawaii and Tahiti. The findings of this study have been published in Science Express. Hotspot volcanoes form in the middle of tectonic plates,...

Biggest Volcano On Earth At Bottom Of Pacific Ocean
2013-09-05 16:59:25

[ Watch the Video: Pacific Ocean Home To World's Largest Volcano ] Brett Smith for redOrbit.com – Your Universe Online Researchers, led by University of Houston professor William Sager, have been able to confirm the existence of the world’s largest single volcano at the bottom of the Pacific Ocean, according to an upcoming report in Nature Geoscience. Called Tamu Massif, the volcano covers an area about the size of the British Isles. Without a similar volcano here on Earth,...

Predicting Activity Inside And Out For Peruvian Volcanoes
2013-09-03 04:56:24

April Flowers for redOrbit.com - Your Universe Online Underneath volcanoes, water and fire coexist to generate “hydrothermal” systems. These systems are complex “steam engines” that produce white smoke – fumaroles – sometimes observed at the surface. A new study, led by the Institut de Recherche pour le Developpement (IRD), demonstrates why these hydrothermal reservoirs are not always found under volcanic peaks. The volcanologists conducted their study at the Ticsani and...

Supervolcanic Ash Can Transform Into Lava Miles Away From Eruption
2013-08-28 06:33:27

Lawrence LeBlond for redOrbit.com - Your Universe Online New research has taken a closer look at how ash produced from supervolcanoes can turn back into lava once it falls back to Earth. Supervolcanoes, such as the Yellowstone caldera, are capable of producing eruptions thousands of times stronger than normal volcanoes. Such a massive eruption can produce an ash cloud that is so hot it has the ability to re-form into lava once it hits the ground much farther away. This evidence was...

Eruptions Not Always Imminent From Slow Magma
2013-08-20 04:41:19

April Flowers for redOrbit.com - Your Universe Online A new modeling study from the University of Washington reveals reservoirs of silica-rich magma of the sort that causes the most explosive volcanic eruptions can persist for hundreds of thousands of years in the Earth’s upper crust without triggering an eruption. In other words, regions such as Yellowstone National Park, known to have experienced a massive volcanic eruption in the past, could have a large pool of magma festering...

Scientists at the University of Bonn simulate that seismic waves can be focused like in a parabolic reflector In 2006 the island of Java, Indonesia was struck by a devastating earthquake followed by the onset of a mud eruption to the east, flooding villages over several square kilometers and that continues to erupt today. Until now, researchers believed the earthquake was too far from the mud volcano to trigger the eruption. Geophysicists at the University of Bonn, Germany and ETH Zurich,...

Corn Syrup Model Predicts Yellowstone Geophysical Behavior
2013-07-15 11:07:37

Brett Smith for redOrbit.com - Your Universe Online In an experiment that could be described as a science fair exhibit on steroids, researchers from Australia and the United States have created a model explaining the geophysical processes occurring in the Pacific Northwest using corn syrup, fiberglass and a series of pistons. Before computer models were generated using state-of-the-art processing power, scientists relied on simple models made from everyday materials. According to the...

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...

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....

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...

Santa María Volcano
2014-04-09 10:58:40

Santa María Volcano is an active stratovolcano that is located in Guatemala and is part of the Sierra Madre, a string of volcanoes that stretches across the western side of Guatemala. The volcanoes in this string were formed by subduction activity, when the Cocos Plate moved under the Caribbean Plate. An eruption in 1902 produced a crater that now holds a lava dome known as Santiaguito, which was created during another eruption in 1922. These domes hold active vents and in 1929, part of the...

  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
