It is thought that water can act as a lubricant between rocks to let them slip sooner than they usually would. Injecting water deep underground has been suspected as a factor in other quakes.
Man caused earthquakes. What will the Communist ruling elite think of next?

FReepmail me if you want on or off my health and science ping list.
There was a huge reservoir built in Riverside County, CA a decade ago near the San Jacinto fault. Among the assumptions was that it might trigger a mid-size quake when filled.
So far, so good, but it might still happen.
Seismologists knew that several hundred million tons of water had filled the reservoir in the preceding few years and that either the water itself or its weight might have weakened a nearby fault and unleashed the quake.Weird that this human activity (building a reservoir) caused a quake, considering that the reservoir didn't exist when all the other deadly quakes hit the same region throughout recorded Chinese history. :') Thanks neverdem.
