Earthquakes Rattle California, Largest In 34 Years Hits Yellowstone
2014-03-31 11:15:34

Lawrence LeBlond for redOrbit.com - Your Universe Online CALIFORNIA As many as 30 earthquakes were recorded in California over the past 24 hours, most of which were less than a magnitude in intensity. Despite all the tremors regional seismometers pick up in California and Nevada -- 808 in the past week alone -- most go unnoticed by residents. The lack of a significant earthquake in the region also poses a problem to emergency management officials, who want Californians to be prepared...

YellowStone's Volcanic Caldera Much More Super Than Estimated
2013-12-17 15:35:14

[ Watch the Video: Yellowstone Volcano Bigger Than Estimated ] Lee Rannals for redOrbit.com - Your Universe Online A supervolcano located in Yellowstone National Park is much larger than previously thought, according to research presented at the American Geophysical Union last week. The new study finds the supervolcano is about 2.5 times bigger than earlier estimates, stretching for more than 55 miles. Researchers used a network of seismometers situated around the national park to...

US Supervolcanoes: Yellowstone-Check, Utah-Check, Wait... Utah?

[ Watch the Video: Add Another Supervolcano To North America's List ] Brett Smith for redOrbit.com - Your Universe Online Geologists from Brigham Young University in Utah have found evidence of a massive supervolcano near the Utah-Nevada border that had a massive eruption around 30 million years ago some 5,000 times larger than the Mount St. Helens eruption in 1980, according to a new report published in the journal Geosphere. “In southern Utah, deposits from this single eruption...

Yellowstone Volcano Debate: Both Sides May Be Right
2013-04-16 05:23:36

April Flowers for redOrbit.com - Your Universe Online The geologic formation of the supervolcano encompassing the Yellowstone National Park region has been the subject of much debate. A new study, led by the University of Rhode Island's Professor Christopher Kincaid, provides new evidence that may put an end to the debate by demonstrating both sides may be right. The international team of scientists used a state-of-the-art plate tectonic laboratory to show the volcanism in the...

The early April earthquake of magnitude 8.6 that shook Sumatra was a grim reminder of the devastating earthquakes and tsunami that killed tens of thousands of people in 2004 and 2005. Now a new study, funded by the National Science Foundation, shows that the residents of that region are at risk from yet another potentially deadly natural phenomenon — major volcanic eruptions. Researchers from Oregon State University working with colleagues in Indonesia have documented six major...

Yellowstone: New Picture Emerges Of A More Active, Less 'Super' Volcano
2012-04-30 08:36:47

Brett Smith for Redorbit.com New research is casting doubts on the frequency or even the possibility of a ℠super-eruption´ that could blot out the sun from the Earth with a thick veil of volcanic ash. A joint research team from Washington State University and the Scottish Universities Environmental Research Centre said the biggest Yellowstone eruption on record was actually two different eruptions at least 6,000 years apart. According to the study published in the June...

Supervolcanoes are one of nature's most destructive forces. In a matter of hours, an eruption from a supervolcano can force thousands of cubic meters of molten rock above ground, and scar landscapes with massive calderas and craters. These catastrophic eruptions have a global impact, and yet scientists still do not fully understand them. Today, a team of scientists studying Bolivia's Uturuncu volcano is trying to shed some light on how supervolcanoes can become so powerful. Uturuncu,...

Image 1 - NASA: No Evidence Of 2012 Supervolcano
2011-11-15 11:46:51

NASA said on Tuesday that there is no evidence of a massive supervolcano erupting in 2012, despite what some may believe. A supervolcano refers to an explosive volcanic eruption that eject about ten thousand times the quantity of magma and ash that Mount St. Helens expelled in 1980. NASA said Earth's surface has preserved clues of many massive supervolcanoes through hollowed-out calderas-craters that can be as big as 60 miles across after a volcano collapses from emptying out its entire...

Scientists Find Possible Trigger For Volcanic 'Super-eruptions'
2011-10-13 03:35:17

The "super-eruption" of a major volcanic system occurs about every 100,000 years and is considered one of the most catastrophic natural events on Earth, yet scientists have long been unsure about what triggers these violent explosions. However, a new model presented this week by researchers at Oregon State University points to a combination of temperature influence and the geometrical configuration of the magma chamber as a potential cause for these super-eruptions. Results of the...

The composition of a vast plume of hot rock and briny fluid 200 miles beneath Yellowstone National Park's surface has been mapped, a soon-to-be published study says. Researchers are able to receive a clear picture of the type of material that activates Yellowstone's volcanic features through these "geoelectric" images of the plume, says study co-author Robert B. Smith, professor emeritus at the University of Utah and coordinating scientist of the Yellowstone Volcano Observatory. "This is the...

Yellowstone National Park
2013-04-17 13:14:01

Yellowstone National Park is located in the United States. The majority of the park is located in Wyoming, but there are smaller areas of the park in Idaho and Montana. It is thought that this area was the first to be established as a national park in the entire world. The area was home to Native Americans for about 11,000 years, but was not well known to Americans until the 1860’s, when the first organized explorations were conducted there. The Lewis and Clark Expedition in the 19th...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
