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,...

Earth's Origins May Be Explained Through Mantle's 'Hidden Flux'
2013-07-17 14:46:32

Brett Smith for redOrbit.com - Your Universe Online One of the more popular theories surrounding the formation of the planets involves the countless collisions of smaller objects in orbit around the sun 4.5 billion years ago. However, proponents of that theory are missing one thing: the Earth's chemical composition is distinctly different from the meteors that are currently striking the planet. Scientists have found that the lead-uranium ratio of meteors is much different than that of...

Volcanoes Like To Scream Out Before They Blow Their Lids
2013-07-15 13:47:55

Brett Smith for redOrbit.com - Your Universe Online Scientists often detect a series of small earthquakes just before a volcanic eruption and a new study published in the Journal of Volcanology and Geothermal Research has shown that these tremors can happen in such a rapid succession -- that they create sound vibrations that rise in pitch until the volcano erupts. The study authors came to their conclusion by looking at the March 2009 eruption of Alaska's Redoubt Volcano, which was...

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...

Global Distribution Of Sulfur Particles Following Large Eruptions Modeled By GEOMAR Researchers
2013-07-08 10:29:07

GEOMAR Helmholtz Centre for Ocean Research Kiel How severely have volcanoes contaminated the atmosphere with sulfur particles in past millennia? To answer this question, scientists use ice cores, among others, as climate archives. But the results differ, particularly in some major volcanic major events of the past, depending on whether the cores come from Antarctica or Greenland. Atmospheric scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Max Planck Institute...

ESA Images Mars Largest Volcano
2013-07-05 12:20:47

Brett Smith for redOrbit.com - Your Universe Online Recently released images from the European Space Agency's (ESA) Mars Express revealed new details of the largest known volcano in our solar system, Olympus Mons. The inactive Martian volcano rises to approximately 22,000 feet above the surrounding plain, which is more than twice the height of Earth's 10,000-foot high Mauna Kea volcano. Like Mauna Kea, Olympus Mons is a shield volcano, with gently sloping sides that extend outward in...

American Museum Of Natural History To Preserve Lonesome George
2013-07-03 11:50:35

Lee Rannals for redOrbit.com - Your Universe Online Lonesome George, a 100-year-old giant tortoise that once lived on the Galapagos Islands, is going to be preserved by the American Museum of Natural History in New York City. Scientists made the surprising discovery of Lonesome George on Pinta Island in 1972. They had thought his species, Geochelone nigra abingdoni, was already extinct before then. The famous tortoise passed away in June 2012, found lifeless near his favorite watering...

Human Influences Endangering Galapagos Sea Lions
2013-07-01 09:35:06

Brett Smith for redOrbit.com - Your Universe Online Like all biological functions, the immune system places demands on an organism and a new study in the journal PLoS ONE has found the highly active immune systems of some endangered Galapagos sea lions are stressing the animals to the point of starvation. In the study, the researchers compared two sea lion populations living within the archipelago: those near the human populated Islands of San Cristobal and those living by 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...

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....

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.
