  • Missing MH370: Seismic Activity Detected After Plane Went Off Radar

    A research team from China's University of Science and Technology detected tremors in the sea near the Malaysia Vietnam border on March 8 hours after MH370 disappeared from the radar screen. In a report published on its website, the Wen Lianxing Research Team said it suspected the tremor to relate to the missing MAS plane because the area "is not within seismic zone." "The incident happened at 2.55am on March 8, about one-and-a-half hours after MH370 lost contact at 1.30am. "One of the two possible locations is (an area) about 116km to the northeast of MH370's last confirmed location," it...

    For decades, the giants of the oil industry were confounded by salt. While oil companies for years had shot sound waves into the deep to help create images of undersea geology, salt located far under the floor of the Gulf of Mexico was unpredictable. It muffled reflections, or bounced them away from survey vessels, leaving geophysicists in the dark. But that was before a series of recent seismic imaging breakthroughs involving supercomputers and the largest moving objects in the ocean. The advancements helped oil companies peek under salt layers located miles below the Gulf and have spurred a number of...

    Israel conducted a massive controlled explosion to calibrate instruments at seismic monitoring stations worldwide, officials said. Using 100 tons of explosives, The Geophysical Institute of Israel conducted the explosion at a site in the Negev on Wednesday. It registered 2.7 on the Richter scale, and created a mushroom cloud that reached the height of up to 1.78 miles, or three kilometers, Haaretz reported Thursday. Local scientists and scientists from the U.S. and France as well as journalists observed the blast. Dr. Rami Hofstetter, head of seismology at the Geophysical Institute told the newspaper the experiment was important to study how...

    BOSTON – In an epic upset in liberal Massachusetts, Republican Scott Brown rode a wave of voter anger to defeat Democrat Martha Coakley in a U.S. Senate election Tuesday that left President Barack Obama's health care overhaul in doubt and marred the end of his first year in office. The loss by the once-favored Coakley for the seat that the late Sen. Edward M. Kennedy held for nearly half a century signaled big political problems for the president's party this fall when House, Senate and gubernatorial candidates are on the ballot nationwide.

    Two U.S.-based scientists said Sunday they've located the site of North Korea's second nuclear test last year more precisely than ever before, pinpointing it just 2 kilometers off the place where the first test was conducted in 2006. Lianxing Wen, a geophysics professor at the State University of New York in Stony Brook, and his graduate student, Hui Long, located the epicenter of the second nuclear test on May 5 last year with a margin of error of only 140 meters, compared with 3.8 kilometers achieved by the U.S. Geological Survey. "We locate the 2009 test at 723 meters north...

    Redoubt volcano erupted for the second time this morning with a huge explosion at 9:24 that sent a cloud of ash to 65,000 feet above sea level. It looks like the plume is going to drift kind of over Prince William Sound and then into the Copper River, Cordova area, and then into the Panhandle," said Alaska Volcano Observatory geologist Chris Waythomas in Anchorage. "It could cause some real serious issues for aviation throughout the day, and I wouldn't be surprised if some flights are going to be canceled here," he said. Alaska Airlines officials said they are still evaluating...

    Posted this question on another thread but had very little response. As I look at the ring of fire right now, there is a massive amount of activity, BIG activity in the Pacific ocean towards Asia. There is also a lot of activity in South America and a little in Central America. The only thing on my chart on the west coast that registered at 4.0 or above was a small quake in Oregon. Question is, with all of these plates shifting, and the plates around our nation's plates staying pretty quiet, what is this doing to our risks of...

    Source: University of Southern California Date: August 27, 2007 Los Angeles Enjoying 1,000 Year Seismic Lull Science Daily — The Los Angeles basin appears to be in a seismic "lull" characterized by relatively smaller and infrequent earthquakes, according to a study in the September issue of Geology. By contrast, the Mojave Desert is in a seismically active period. Seismic activity alternates between the two regions, the study suggests. The lull in the Los Angeles basin began 1,000 years ago, said the authors, led by James Dolan, associate professor of earth sciences at the University of Southern California. "The past 1,000...

    Source: University of Kentucky Date: December 14, 2006 Researchers Complete Seismic Borehole In Kentucky Drilling has been completed on the deepest borehole for seismic instruments in the eastern U.S. The four-inch diameter hole for the Central U.S. Seismic Observatory (CUSSO), located at Sassafras Ridge in Fulton County, Kentucky, reached a depth of 1,948 feet, where bedrock was encountered. The location is near the most active part of the New Madrid Seismic Zone, the source of at least three major earthquakes in the winter of 1811-12, before the region was heavily populated and developed. This location will allow instruments in the...

    Active volcanoes are being made to "sing" by researchers who convert seismic data into frequencies audible to human ears. Although the volcanoes are unlikely to sell many records, the technique could make it easier to detect patterns that warn of an eruption. High-powered computers are being used to convert seismic readings from Mount Etna in Sicily and Tungurahua in Ecuador into audible rumbles, roars, beeps, and even piano music. The technique, known as "sonification", is used to help people detect patterns in complex data. Research has shown that people find it easier to detect patterns audibly rather than visually. While...

    The USGS is releasing a new tool to help mitigate loss of life and property - a 3D computer model of the upper 20 miles of the Earth's crust in the greater San Francisco Bay Area that will enable researchers to accurately predict the shaking levels of past and future earthquakes. Previous work by the USGS and others has shown that the 3D structure of the Earth has a significant impact on how strongly an earthquake is felt at different locations and on the duration of the shaking. Because seismic waves propagate through different rock types with differing speeds that...

    SACRAMENTO — State Senate leader Don Perata officially unveiled legislation Wednesday to fund huge Bay Bridge cost overruns and other seismic-retrofit needs throughout the state with a multibillion-dollar bond that would go to voters. Gov. Arnold Schwarzenegger has indicated he would consider Perata's Essential Facilities Seismic Retrofit Bond. Both developments, foreshadowed by the Oakland Tribune last month, could lead to the bond's being placed on the expected November special election ballot. But at the same time, the Republican governor has told the Democratic Senate president pro tem from Oakland that he is still interested in replacing the single-tower suspension span...

    SACRAMENTO — While declining in popularity and blasting Democrats, Republican Gov. Arnold Schwarzenegger left the way open Wednesday to put a huge seismic-safety bond before voters this year for the Bay Bridge and other needs statewide. The governor's comments came in the wake of Senate leader Don Perata, D-Oakland, acknowledging that he was considering the tactic but had not approached the governor. On learning of the governor's remark, Perata said he planned to huddle with other legislative majority Democrats, aides said. During wide-ranging questions after an address to the Sacramento Press Club, Gov. Schwarzenegger — asked specifically if he supported...

    Throughout the 1990s, Turkish foreign policy analysts had an easy job. After all, Turkish foreign policy was predictable. Ankara cooperated enthusiastically with Washington, whether in the Middle East or in the Balkans. Turkey aligned itself with Israel and kept at arms length from Middle Eastern neighbors such as Syria and Iran. In Europe, Ankara traded heavily with the European Union (EU) but did not allow the EU to dictate foreign policy. The European Union's frequent allegations and criticism of human rights abuses in Turkey, especially with regard to Turkey's fight against Kurdistan Workers Party (PKK, Partiya Karkaren Kurdistan) terrorists, soured...

In fact, nearly all of coastal California from north of Eureka to the Mexican border, where more than 70 percent of the state's population lives, is red. So are the southern inland deserts.</p>
