At the time of the temblor, another microquake has occurred near Bulgaria's town of Pernik with a magnitude of 2.
The microquake technique could have uses elsewhere.
The studied earthquakes - actually microquakes no stronger than magnitude 2 -were so far down, they were not felt on the surface.
While microquakes aren't themselves damaging to buildings or infrastructure, detecting them can provide valuable clues towards predicting larger, more threatening earthquakes.
A new algorithm designed to find matching seismic signals in large earthquake databases could find previously missed microquakes.
Scientists have not concluded that there is a causal connection between the fracking process and major earthquakes, but that the process causes microquakes that are not felt and increased seismic activity "coincides with the injection of wastewater in deep disposal wells" (Ellsworth, Robertson & Hook, 2014; see, Ellsworth, 2013; Frohlich, 2012; Petersen, Mueller, Moschetti, Hoover, Rubinstein, Llenos, Michael, Ellsworth, McGarr, Holland, & Anderson, 2015).
Most of the roughly 80 induced microquakes began at least a few meters away from the injection site, where the pumped-in water hadn't reached.
can cause microquakes that are rarely strong enough to register on monitoring equipment.
Seismologists know hydraulic fracturing can cause microquakes, yet they and the oil and gas companies have taken pains to point out that a clear correlation has not been established.
Moore spotted the talc along a segment of the San Andreas Fault known to produce microquakes rather than huge tremors.
The recorded seismicity reflects the geological situation in the area: local tectonic earthquakes with hypocentres in southern Bohemia are normally found as microquakes, whereas stronger ones are registered from the Alpine region.
