Pakistan Earthquake Creates a Mud Volcano Island
On Tuesday, a 7.7-magnitude earthquake struck a remote part of western Pakistan, killing more than 260 people and displacing hundreds of thousands. It also triggered formation of a new island off the coast, which has quickly become a global curiosity. But scientists say the island won't last long.

“The island is really just a big pile of mud from the seafloor that got pushed up,” said Bill Barnhart, a geologist at the U.S. Geological Survey who studies earthquakes in Pakistan and Iran. “This area of the world seems to see so many of these features because the geology is correct for their formation. You need a shallow, buried layer of pressurized gas—methane, carbon dioxide, or something else—and fluids. When that layer becomes disturbed by seismic waves (like an earthquake), the gases and fluids become buoyant and rush to the surface, bringing the rock and mud with them.”
