I was talking about an increase in small quakes, like a cluster of small quakes. On that scale, there really isn't such a thing as a solid plate. In between major faults there are all sorts of differing materials, especially in a place as geologically diverse as China.
I recall a paper back in the '70's of a study done at a new dam site in Colorado where they discovered that this actually happens --- that clusters of small quakes can occur as a new dam fills.
What I'd be interested in seeing is a study that shows whether such a cluster, if it occured in China, is physically related to the major fault that had the big quake.
