"A powerful earthquake jolted China's Sichuan province Saturday near where a devastating quake struck five years ago," The Associated Press writes. According to CNN, early estimates put the death toll around 100. More than 1,000 other people were reportedly injured. Both figures could change substantially as more information comes in.
The new boom in natural gas from shale has changed the energy economy of the United States. But there's another giant reservoir of natural gas that lies under the ocean floor that, theoretically, could dwarf the shale boom.
No one had tapped this gas from the seabed until this week, when Japanese engineers pulled some up through a well from under the Pacific. The gas at issue here is called methane hydrate. Methane is natural gas; hydrate means there's water in it. In this case, the molecules of gas are trapped inside a sort of cage of water molecules.
