Earthquake!

Any student of history knows that Kathmandu gets a major earthquake every 100 to 125 years or so. Every student of engineering (or possibly even the casual observer) knows that most buildings in this city will come down when this happens. So inevitably in the not so distant future Kathmandu will be flattened, this isn't a matter of if, but a matter of when. In the world there are two locations that are listed as potential catastrophic disasters with a major earthquake hits, and Kathmandu is one of them.
