#Major 7. 3-Magnitude Earthquake Aftershock Hits Nepal A 7. 3-magnitude earthquake struck Nepal this morning (May 12), toppling buildings and killing at least a dozen people.
The temblor was centered 11 miles (18 kilometers) southeast of Kodari, Nepal, and 47 miles (76 km) east-northeast of the Nepalese capital of Kathmandu.
a magnitude-7. 8 earthquake (called the Gorkha earthquake) located about 90 miles (150 km) to the west of this aftershock, according to the U s. Geological Survey.
The May 12 earthquake occurred due to faulting associated with the Main Himalayan Thrust where the India plate is slamming into the Eurasia plate to the north.
This area has a history of powerful earthquakes: Before the April 25 temblor, four magnitude-6 or larger earthquakes within 155 miles (250 km) of this area in the past century, according to the USGS. One such event, a magnitude-6. 9
quake killed nearly 1, 500 people in August 1988. The largest of these, a magnitude-8. 0 earthquake known as the 1934 Nepal-Bihar earthquake, ruptured a large part of the fault to the south of the May 12 quake
and caused around 10,600 fatalities, the USGS reported. Like the April 25 earthquake, this one was relatively shallow,
occurring just 9. 3 miles (15 km) belowground; the shallower a quake the more shaking at the surface, geologists say.
Earth scientists had anticipated major aftershocks and even larger earthquakes in the area. In fact, a recent study found that smaller aftershocks strike within the main earthquake rupture,
whereas the biggest aftershocks tend to strike at the edge of where the original earthquake occurred.
And that was the case for this one, which hit on the eastern edge of the April 25 rupture zone.

#Desalination with nanoporous graphene membrane Less than 1 percent of Earth's water is drinkable. Removing salt and other minerals from our biggest available source of water--seawater--may help satisfy a growing global population thirsty for fresh water for drinking, farming, transportation, heating, cooling and industry.
But desalination is an energy-intensive process, which concerns those wanting to expand its application.
Now, a team of experimentalists led by the Department of energy's Oak ridge National Laboratory has demonstrated an energy-efficient desalination technology that uses a porous membrane made of strong, slim graphene--a carbon honeycomb one atom thick.
The results are published in the March 23 advance online issue of Nature Nanotechnology("Water Desalination Using Nanoporous Single-layer graphene"."
To figure out the best pore size for desalination, the researchers relied on the Center for Nanophase Materials sciences (CNMS),
They determined the optimum pore size for effective desalination was 0. 5 to 1 nanometers,
They also found the optimal density of pores for desalination was one pore for every 100 square nanometers."
This discovery holds out the potential of using this mechanism to help clean up environmental pollution, and other bioengineering applications.
The chemical industry is undergoing a major transformation as a consequence of unstable energy costs, limited natural resources and climate change.
According to recent findings by environmental scientists at Radboud University, the location of the agricultural lands used to grow these biofuel crops has a major impact on the greenhouse gas emission they ultimately produce.
The study that arrived at this conclusion is due to be published By nature Climate change("Greenhouse gas payback times for crop-based biofuels".
While intensive crop farming results in greater greenhouse gas emission, it also increases the yields of crops used to produce biofuels and,
The initial result of this is an increase in greenhouse gas emission. Using a global model, Pieter Elshout and fellow environmental scientists at Radboud University have demonstrated how long it takes for the advantages that biofuels offer over fossil fuels to earn a return on this initial emission On the global scale,
the average payback time for greenhouse gases is nineteen years. This figure shows the duration of the payback times for greenhouse gases produced by corn-based bioethanol,
While extensive crop farming reduces greenhouse gas emission, it also yields smaller crops for producing biofuels. From Western europe to the tropics Elshout, a Phd candidate at Radboud University, explains:
The model demonstrates that the location of biofuel crops has a significant impact on greenhouse gas emission more so than does the type of crop

#Massive Earthquake Shakes Nepal; Avalanches On Everest An earthquake struck Nepal early Saturday causing numerous casualties,
large amounts of damage to structures and avalanches on Mount everest where a closely watched climbing season was started just getting.
The magnitude 7. 8 earthquake occurred only 50 miles away from Nepal's capital, Katmandu.
Last year, an avalanche in April killed 16 Sherpa guides, a tragedy that brought the climbing season to an abrupt end.
But the movement of the earth's tectonic plates isn't like the smooth movement of gears in a machine.

A 2005 earthquake in neighboring Kashmir killed 75,000 people, and left millions homeless. Those kinds of large earthquakes aren't as common in Nepal.
The USGS reports that in the past 100 years only four earthquakes larger than a magnitude 6. 0 on the Richter scale have occurred in the immediate area.
The most recent was in 1988, a 6. 9 temblor that killed 1500. The largest in that time frame was a magnitude 8 in 1934 that killed around 10,000,
But just because a large earthquake hadn't occurred in Nepal recently didn't mean that people weren't worried about it.
Early calculations suggest that this magnitude 7. 8 earthquake is probably not big enough to rupture all the way to the surface,
and we should probably expect another big earthquake to the west and south of this one in the coming decades, Laurent Bollinger,

-And-Trade Program To Limit Carbon emissions President Xi Jinping of China announced today during a visit to the White house that China will start a national cap
-and-trade program to limit greenhouse gas emissions in 2017. Under cap-and-trade programs, a governing body limits the amount of pollution that can be emitted,
and then sells permits to companies that want to emit pollutants. Companies can trade their permits,
creating a market for emissions and providing an economic incentive for companies to reduce their carbon footprint.
The announcement comes on the heels of last November climate accord between the U s. and China
In 2013, China accounted for nearly 30 percent of total global carbon emissions, with many of its emissions coming from coal fired power plants,
and making China the largest contributor to modern climate change. However the United states still exceeds China by more than double in per capita emissions,
which Chinese officials have argued are a better yardstick for contributions to global climate change. China has yet to announce specifics about its cap-and-trade plan, leaving some concerned about the political and technical challenges that lie ahead."
"said Timmons Roberts, a professor of environmental studies at Brown University.""It really does matter what the actual cap is."
"Cap-and-trade programs have been praised by some policymakers as an efficient way to reduce global greenhouse gas emissions,
while others argue that the strategy rewards big polluters that can afford to buy permits. In his first term, President Obama tried to pass a similar cap-and-trade program,
. and China to lead discussions at the UN climate change conference that will take place in Paris in December.'
