Fluid Injection's Role in Man-Made Earthquakes Revealed
Usually small though occasionally damaging earthquakes are a side-effect of industrial processes such as geothermal energy and oil-gas production that involve injecting water underground. But scientists have been unclear about the exact role of fluid injection in triggering these man-made earthquakes.
Now, for the first time, researchers at Caltech and other institutions in the United States and France have observed how fluid injection sets off microearthquakes on a sizable, subterranean fault. The findings could lead to better seismic risk management through improved understanding of fluid flow on faults, while also illuminating the mechanics of natural earthquakes.

Thanks Brian, forwarded the link to Leonardo "Nano" Seeber and Marie-Helene Cormier. Note that there are a whole series of papers in that issue on fluid injection. I wanted to work with Pierre Henry, a co-author of the one you linked to, on Turkey, but it seems there is an issue in Turkey with sharing data: it is in the Turkish public interest to share data, but it there are problems (there are problems in USA also). I spent 10 days in Marseille at my own expense to work with Pierre, a Turkish student, and recent Ph.D Celine Grall. One of the two manuscripts was going to be on the thrust-fold belt along one side of the North Anatolian fault.
