Predicting the date and time of an earthquake is impossible, but seismologists can use trends in tectonic activity to suggest where a big tremor might occur. A recent study revealed a massive, hidden fault line running under miles of river sediment . Scientists suggest the fault, which runs beneath Bangladesh, parts of east India and Myanmar, could cause a magnitude 8.2 to 9.0 earthquake. A quake of that strength would be devastating in such a densely populated region. http://vimeo.com/26131107 The recently discovered fault has created a lot of work for researchers, who are eager to learn more about it. However, since the fault has been hidden for so long, seismologists aren’t able to say as much about it as other faults around the world that have been under close watch for decades. Without knowledge of the fault’s trends over time, little can be done to protect the very people who might suffer if a major earthquake occurs along the fault line. Related: NASA says ionized air molecules may help predict earthquakes “We don’t know if it’s tomorrow or if it’s not going to be for another 500 years,” said study co-author Michael Steckler, a geophysicist at the Lamont-Doherty Earth Observatory (LDEO) at Columbia University in New York City. Steckler and his colleagues discovered the fault while working to map plate-motion data throughout Bangladesh, India, and Myanmar. The team, working with researchers at Bangladesh’s Dhaka University , used ultrasensitive GPS devices throughout Bangladesh between 2003 and 2014 to collect the data, which revealed the existence of this previously unknown fault. Researchers estimate that some 140 million people live within a 60-mile radius of the fault and, because of unsustainable building practices (like pumping sand out of the ground to build up areas for skyscrapers ), a major earthquake in the region would leave countless casualties and massive infrastructure damage. The results of the study were published this week in the journal Nature Geoscience . Via CBS Images via Wikipedia and  LDEO

Certain earthquakes threaten skyscrapers more than others

Comments Off on Certain earthquakes threaten skyscrapers more than others

It’s not the size of the earthquake so much as its rate of oscillation that determines the extent of injuries and damage, suggest two scientific papers published recently. Following the 7.8 magnitude earthquake near Kathmandu in April, experts expected the number of deaths to be comparable to a 2005 quake that hit a less-populated area of Kashmir. The actual death toll was close to 9,000 in Nepal, nowhere near the 85,000 people who died in the earlier quake. That “is actually a small number given the density of the population in the Kathmandu area and the vulnerability of the buildings,” Jean-Philippe Avouac, the author of the papers, told The New York Times.

Is the Massive Rise in Oklahoma Earthquakes Due to Fracking?

Comments Off on Is the Massive Rise in Oklahoma Earthquakes Due to Fracking?

Fracking photo / Shutterstock In a state where residents regularly brace themselves for tornados, Oklahomans now have another disturbing hazard to watch out for: earthquakes . In recent years, there’s been a steady and worrying uptick in quake activity with almost 3,000 quakes in 2013—the state’s most seismically active year ever. As rattled Oklahomans eye the ground warily, researchers and environmentalists say that fracking and other oil and gas extraction techniques are likely to blame for the recent quakes. In October, the U.S. Geological Survey reported that fracking and its wastewater disposal methods could be linked to the over tenfold increase in Oklahoma’s earthquake activity since 2009. The controversial drilling practice involves injecting massive amounts of wastewater deep into the ground, which increases pressure along fault lines and makes them more susceptible to rupture. Research also warns that fracking may have been the reason behind a magnitude 5.7 quake in November 2011–the largest earthquake ever recorded in the state–that damaged 14 homes and injured two people. Though many of the quakes are mostly minor and register around magnitude 3.0, the yearly average for earthquakes has been rising to about 40 per year since 2008. Seismic swarms have also rippled across parts of the country in similar toxic wastewater disposal sites, where nearby faults become overloaded by fracking’s high-pressure injections. Although research has shown a high correlation between earthquakes and fracking’s wastewater wells, scientists and regulators still lack the necessary proof to back new laws to protect residents. In the meantime, worried Oklahomans are starting to turn to earthquake insurance. Via NPR Images via Wikimedia
