The Kashmir region in northwestern India could experience a magnitude 9 earthquake — several times larger than previously assumed. The revised risk estimate is worrying, says Roger Bilham of the University of Colorado, Boulder, who presented the results on 7 December at the American Geophysical Union meeting in San Francisco. “There are many cities and megacities in the region. And there are a couple of nuclear power plants there too,” he says. “You have two nuclear powers facing each other, armed to the teeth, facing a huge amount of damage”. Bilham speculates that perhaps 300,000 people might die in such an earthquake, not counting subsequent problems from political turmoil between India and Kashmir, or flooding.
