..., stress release associated with overall rupture and sub-events which is suggestive of decreasing frictional resistance due to the presence of fluids. Magnitudes for sub-events increase suggesting increasing rupture surface akin to increased slip over a larger contact area such as an asperity. Rupture...

... based on the stress release of the events. As summarized recently by Hough (2014) for other fluid-induced seismicity, the lower stress releases typical for these sequences results in on-average less shaking than is observed for equivalent magnitude tectonic events. In order to quantify shaking over...

.... A consistent stimulation program was utilized over all stages, however, following a shutdown interval of two days, upon re-initiation of the stimulation program, events migrated out-of-zone into the surrounding carbonate layers. These events were characterized by higher stress release values, consistent...
