San Andreas Fault Wouldn't Stop Statewide California Quake
2013-01-12 07:54:47

redOrbit Staff & Wire Reports — Your Universe Online Assumptions that the San Andreas Fault would automatically prevent an earthquake from affecting both northern and southern California at the same time may not necessarily be true, according to a new study published Wednesday in the online edition of the journal Nature. According to Eryn Brown of the Los Angeles Times, geologists have assumed for several years that the fault line would act as a barrier, preventing seismic...

Tsunami Warning Cancelled After Earthquake Off Alaska Coast
2013-01-06 05:09:45

redOrbit Staff & Wire Reports - Your Universe Online Residents of Alaska and parts of Canada were briefly under a tsunami warning on Saturday after a strong earthquake rocked the region, but the alert was later cancelled because no potentially destructive waves resulted from the trembler. According to the United States Geological Survey (USGS), the magnitude 7.5 seismic event took place approximately 58 miles west of Craig, Alaska at approximately midnight local time (08:58:19 UTC)....

Himalayas Will Have More Massive Earthquakes, Warn Scientists
2012-12-31 11:33:53

Brett Smith for redOrbit.com - Your Universe Online An international team of researchers has found that a pair of massive, historical earthquakes ruptured the surface in the central Himalayas–leading them to theorize that similar quakes will threaten the region´s population in the future. According to the team´s report in Nature Geosciences, the two quakes, in 1255 and 1934, measured between 8 and 8.5 magnitudes on the Richter scale and both left distinct scars in...

A research team led by scientists from Nanyang Technological University (NTU) has discovered that massive earthquakes in the range of 8 to 8.5 magnitudes on the Richter scale have left clear ground scars in the central Himalayas. This ground-breaking discovery has huge implications for the area along the front of the Himalayan Mountains, given that the region has a population density similar to that of New York City. NTU Professor Paul Tapponnier, who is recognized as a leading...

A new look at the science of plate tectonics Saint Cloud, Fla. (PRWEB) December 17, 2012 “When plate tectonics is viewed as a cycle, it can be imagined to start and restart with eruptions at the earth´s ride and rise system,” explains author and professor John H. Carman. To help explain to readers this geological occurrence, Carman pens his new book, “How the Earth's Plate Tectonic Cycle Works: CMB Reaction” In his new book, Carman offers a new thesis in the...

Using Seismic Waves To Detect Tunnels Is Not As Simple As It Sounds
2012-12-10 15:01:35

Sandia National Laboratories You´d think it would be easy to use seismic waves to find tunnels dug by smugglers of drugs, weapons or people. You´d be wrong. Nedra Bonal of Sandia´s geophysics and atmospheric sciences organization is nearing the end of a two-year study, “Improving Shallow Tunnel Detection From Surface Seismic Methods,” aimed at getting a better look at the ground around tunnels and learning why seismic data finds some tunnels but not others....

Powerful Magnitude 7.0 Earthquake Rocks Japan, Touches Off Small Tsunami
2012-12-07 09:00:09

Lawrence LeBlond for redOrbit.com - Your Universe Online Japan, still reeling with the aftermath of a powerful earthquake and destructive tsunami in March 2011, has been hit again. A magnitude 7.3 earthquake struck off the coast at 5:18 p.m. local time Friday evening triggering a small 3-foot-high tsunami that swept against the Japanese mainland nearly 45 minutes later. Evacuation orders came streaming in over TV and radio channels shortly after the quake struck and countless coastal...

Technique provides insight into ancient formation of underwater plateau Scientists have long used the speed of seismic waves traveling through the Earth as a means of learning about the geologic structure beneath the Earth's surface, but the seismic waves they use have typically been generated by earthquakes or man-made explosions. A University of Rhode Island graduate student is using the tiny seismic waves created by ocean waves crashing on shorelines around the world to learn how an...

Scientists Warn Of Major Earthquakes In Himalayas And Pacific Northwest
2012-12-04 15:18:09

Lee Rannals for redOrbit.com — Your Universe Online Scientists at the American Geophysical Union meeting in San Francisco this week reported that the Himalayas and Pacific Northwest could experience major earthquakes. Researchers have begun studying the complexity of the Himalayan range in greater detail, particularly the fault that separates the two plates known as the Main Himalayan Thrust (MHT). Previous observations indicated a fault that dipped a few degrees to the...

Russian Far East A Hotbed Of Seismic, Volcanic Activity: Potential Threat To Pacific Basin
2012-12-04 13:10:18

April Flowers for redOrbit.com - Your Universe Online The Soviet government has long kept outsiders away from the Russian Far East, shrouding a source of powerful earthquakes and volcanic activity on the Pacific Rim in secrecy. In the last 20 years, however, research has shown that the Kamchatka Peninsula and the Kuril Islands are a seismic and volcanic hotbed. This area has the potential to trigger tsunamis that pose a risk to the rest of the Pacific Basin. As an example, in...

Pacific Ring of Fire
2013-02-19 13:18:27

The Pacific Ring of Fire, or Ring of Fire for short, is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 25,000 mile horseshoe shape, it’s associated with an almost continuous series of oceanic trenches, volcanic belts, volcanic arcs and/or plate movement. The Ring of Fire contains 452 volcanoes and is home to over 75 percent of the world’s active and dormant volcanoes. It’s sometimes called the circum-Pacific belt or the...

The Richter scale assigns a single number to quantify the amount of seismic energy released by an earthquake. The scale uses a base-10 logarithm by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a particular type of seismometer. A earthquake measuring 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0. The moment magnitude, calibrated to give generally similar value for medium-sized...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
