There can't be an earthquake in China without somebody getting killed. You can see that this earthquake is in the zone of compression from the 'Big Crunch' of the Himalayas. This was a shallow thrust in farmland. It could most likely be a 'superthrust', but they will probably find the high-intensity zone out in the country. They should look for thrown rocks. Most of the pictures didn't seem to indicate a high PGV.
