Explosive History Of A 'Celebrity Hotspot' Uncovered
2014-05-21 03:01:15

University of Leicester A tiny Mediterranean island visited by the likes of Madonna, Sting, Julia Roberts and Sharon Stone is now the focus of a ground-breaking study by University of Leicester geologists. Pantelleria, a little-known island between Sicily and Tunisia, is a volcano with a remarkable past: 45 thousand years ago, the entire island was covered in a searing-hot layer of green glass. Volcanologists Drs Mike Branney, Rebecca Williams and colleagues at the University of...

Understanding Mudslides And Other Debris Flows Using mathematics

Ivy F. Kupec, National Science Foundation Mudslides. Landslides. Volcanic debris flows. Avalanches. Falling rocks... They can come along so suddenly that people, homes, roads and even towns are buried or destroyed without much warning. Recently, we've had dramatic reminders of this, such as the mudslide in Oso, Wash., where 41 people died; an avalanche on Mt. Everest that killed 13 experienced Sherpas and another landslide event in Jackson, Wyo. And as much as ancient Pompeii serves as...

redOrbit Staff & Wire Reports - Your Universe Online Using new data obtained by the MESSENGER spacecraft, researchers from Brown University in Rhode Island have discovered that explosive volcanic activity has been occurring throughout most of Mercury’s history, meaning that the planet has had the volatile compounds necessary for those eruptions for longer than anticipated. The findings, which are detailed in a recent edition of the Journal of Geophysical Research: Planets, are...

Two Sources Of Helium Produced By Ancient Yellowstone Activity
2014-02-20 07:33:51

[ Watch the Video: Yellowstone Releasing Ancient Helium ] Lawrence LeBlond for redOrbit.com - Your Universe Online As one might expect, Yellowstone National Park’s hot springs, geysers and other hydrothermal vents release gases stored deep below the Earth, including carbon dioxide and methane. Another gas has also been discovered to be squeaking out of Yellowstone’s vents, and while it is a common gas released from volcanic rocks, in this region, most of it comes from a much...

[ Watch the Video: Pyroclastic Eruptions Preserved Fossil Beds In China ] April Flowers for redOrbit.com - Your Universe Online The exceptional preservation and diversity of dinosaur, bird and early mammal fossils present in the fossil beds of northern China are famous. How these creatures died, and why hundreds of creatures from different habitats were buried together on ancient lake floors, has yet to be understood. A new study, published in Nature Communications, claims that the...

[ Watch the Video: Trolls Not Responsible For Iceland's Basalt Pillars ] Lee Rannals for redOrbit.com - Your Universe Online Icelandic trolls are not responsible for shaping the basalt pillars found on the island, according to a study recently published in the Journal of Volcanology and Geothermal Research. Folklore says that mysterious basalt pillars found in Iceland were created by a pair of angry trolls who hurled rocks at one another. However, the new study says that these...

Volcanic Rock Age Suggests Catalhoyuk Mural Could Be Based On Turkish Eruption
2014-01-09 09:36:28

Public Library of Science Volcanic rock dating suggests the painting of a Çatalhöyük mural may have overlapped with an eruption in Turkey according to results published January 8, 2014, in the open access journal PLOS ONE by Axel Schmitt from the University of California Los Angeles and colleagues from other institutions. Scientists analyzed rocks from the nearby Hasan Dagi volcano in order to determine whether it was the volcano depicted in the mural from ~6600 BC in the...

Volcanic Rock Research Sheds New Light On Earth’s Formation
2013-11-08 12:29:31

redOrbit Staff & Wire Reports - Your Universe Online By analyzing basalt, a substance formed from cooling lava, a team of European scientists have gained new insight into how the Earth’s core, crust and atmosphere formed, as well as how volcanic activity originated. According to UPI, the researchers recreated the conditions of the Earth approximately 4.5 billion years ago, when much of the world was molten and the crust formed as lava cooled. Their goal was to develop a...

mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
