Potential For Tsunamis In Northwestern California
2012-06-28 12:05:44

redOrbit Staff & Wire Reports - Your Universe Online Scientists at UC Santa Barbara have accumulated the first evidence-based inclusive study of the probability for tsunamis in Northwestern California. The paper, "Paleoseismicity of the Southern End of the Cascadia Subduction Zone, Northwestern California," was co-written by professors Edward Keller and Alexander Simms from UCSB's Department of Earth Science, and published in a recent issue of the Bulletin of the Seismological...

Pinta Island’s Lonesome George Passes Away
2012-06-25 10:21:34

Brett Smith for redOrbit.com Sadly, the sudden death of the giant tortoise Lonesome George on the Galapagos Islands this Sunday marks the loss of another subspecies from the face of the Earth. When scientists first met Lonesome George on Pinta Island in 1972, they had thought his species, Geochelone nigra abingdoni, was already extinct. He was immediately placed into the park service´s tortoise breeding program on Santa Cruz Island and while he did mate with a female tortoise...

New Geology articles posted online ahead of print June 15 Orange-like rocks in Utah with iron-oxide rinds and fossilized bacteria inside that are believed to have eaten the interior rock material, plus noted similarities to "bacterial meal" ingredients and rock types on Mars; fine-tuning the prediction of volcanic hazards and warning systems for both high population zones and at Tristan da Cunha, home to the most remote population on Earth; news from SAFOD; and discovery in Germany of the...

Potential Eruption In Iceland Could Pump Acid Into European Airspace
2012-06-12 15:11:11

A modern recurrence of an extraordinary type of volcanic eruption in Iceland could inject large quantities of hazardous gases into North Atlantic and European flight corridors, potentially for months at a time, a new study suggests. Using computer simulations, researchers are investigating the likely atmospheric effects if a “flood lava” eruption took place in Iceland today. Flood lava eruptions, which stand out for the sheer amounts of lava and sulfurous gases they release and...

Warning Signs Of The 2011 Axial Seamount Eruption
2012-06-11 02:53:32

A team of scientists that last year created waves by correctly forecasting the 2011 eruption of Axial Seamount years in advance now says that the undersea volcano located some 250 miles off the Oregon coast gave off clear signals just hours before its impending eruption. The researchers´ documentation of inflation of the undersea volcano from gradual magma intrusion over a period of years led to the long-term eruption forecast. But new analyses using data from underwater hydrophones...

Volcanic Super-Eruptions A Quicker Threat Than Previously Thought
2012-05-31 05:03:53

Lee Rannals for RedOrbit.com Volcanoes capable of super-eruptions that could be catastrophic for civilizations have short fuses, according to new research conducted at Vanderbilt University. Super-eruptions are more than 100 times the size of ordinary volcanic eruptions like Mount St. Helens. These types of eruptions spew out super-heated gas, ash and rock, and are capable of leveling entire continents. Researchers say that there is evidence of one super-eruption that took place in...

Crystal Composition Could Predict Volcanic Eruptions
2012-05-26 05:03:51

By studying crystals formed in volcanic rock, experts may be able to predict an impending eruption up to a year in advance, researchers from the University of Bristol have discovered. According to a Thursday press release from the university, Dr. Kate Saunders and her colleagues used forensic-style chemical analysis to link seismic observations of a 1980 eruption at Mount St. Helens to the growth of crystals within the large underground pool of liquid rock beneath the volcano known as the...

Melting Mantle Linked To Great Oxygenation Event 2.5 Billion Years Ago
2012-05-25 04:38:16

Brett Smith for RedOrbit.com Oxygen-based life evolved on Earth because of geological events that occurred over 2.5 million years ago, according to Princeton University researchers who published a report this week in the online journal Nature. Based on geological evidence, scientists know that roughly 2.5 billion years ago, oxygen levels in the atmosphere exploded and eventually gave birth to our present atmosphere. This time period, dubbed the Great Oxygenation Event (GOE), appears to...

Envisat Captures Nea Kameni Volcano Movement
2012-05-23 03:23:31

[ Watch the Video ] Archived data from the Envisat satellite show that the volcanic island of Santorini has recently displayed signs of unrest. Even after the end of its mission, Envisat information continues to be exploited for the long-term monitoring of volcanoes. Santorini is a picturesque Greek island in the south Aegean Sea and the most active volcanic center in the South Aegean Volcanic Arc. The island is the site of one of history´s largest volcanic eruptions, about 3600...

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....

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...

Pacaya
2014-04-09 10:53:58

Pacaya is an active complex volcano that is located in Guatemala and is part of the Central American Volcanic Arc. It reaches and elevation of 8,373 feet and is located on a volcanic caldera, along with Lago de Amatitlán, that has been the cause of at least nine large explosive eruptions in the past 300,000 years. Its edifice collapsed about 1,100 years ago, producing a landslide that traveled sixteen miles and left a crater where the current cone is still forming. The active magma chamber...

toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
