Massive earthquakes in Chile and Japan have been found to cause the dramatic increase in violent quakes around fracking's largely unregulated wastewater injection wells observed in the Midwest in the past two years, where injected water acts as a lubricant for geological faults that were previously thought to be "dead" or stable for millions of years.

Worth picking up if you have a library with a subscription. The May 20th issue of Science was devoted to the Sumatra-Andaman Earthquake of December 24 describing the full power of that event, the most powerful recorded since the deployment of modern electronic sensors. The multiple effects claimed include swarm earthquakes in Alaska, a shock wave that moved every place on Earth a centimeter, and resonant waves continuing weeks after the event. It is also the the longest rupture recorded and took over an hour to complete. Animated simulations of aspects of the event are linked through PhysOrg.com.
