“…This work confirmed the Dahm et al (2013) recommendation, that full MT solutions should be used whenever it is possible in studies aiming at discrimination of anthropogenic (including recognition of induced and triggered types) and natural seismicity. Following the results of the MT inversions of the human-related and tectonic earthquakes from Poland, the full MT analysis should be a significant part of the discrimination workflow, but it cannot be treated as the main and only input for such discrimination.…”

“…Stec (2007) called the first group ''mining'' events and second ''miningtectonic'' according to full MT solutions. In nomenclature used in this work after the definition of Dahm et al (2013) the first group is called induced seismicity, while the second one is an example of triggered seismicity. Induced events in USCB are characterized by small shearing component in full MT solution of about 10-20 % and very high non-DC components with isotropic component from 20 to 50 %.…”

“…The non-DC component of focal mechanism solution was considered as an indicator of the induced seismicity since 1980's by several authors (e.g., Teisseyre 1980;Rudajev and Š ílený 1985), recently the non-DC component of the MT decomposition is proposed as such indicator . Moreover, recommendation for discrimination of anthropogenic and natural seismicity included use of MT inversion in the complex investigation procedure described in Dahm et al (2013). The authors of the latter work also discriminate between triggered and induced anthropogenic seismicity.…”

Abstract-Tectonic seismicity in Poland is sparse. The biggest event was located near Myślenice in 17th century of magnitude 5.6. On the other hand, the anthropogenic seismicity is one of the highest in Europe related, for example, to underground mining in Upper Silesian Coal Basin (USCB) and Legnica Głogów Copper District (LGCD), open pit mining in ''Bełchatów'' brown coal mine and reservoir impoundment of Czorsztyn artificial lake. The level of seismic activity in these areas varies from tens to thousands of events per year. Focal mechanism and full moment tensor (MT) decomposition allow for deeper understanding of the seismogenic process leading to tectonic, induced, and triggered seismic events. The non-DC components of moment tensors are considered as an indicator of the induced seismicity. In this work, the MT inversion and decomposition is proved to be a robust tool for unveiling collapse-type events as well as the other induced events in Polish underground mining areas. The robustness and limitations of the presented method is exemplified by synthetic tests and by analyzing weak tectonic earthquakes. The spurious non-DC components of full MT solutions due to the noise and poor focal coverage are discussed. The results of the MT inversions of the human-related and tectonic earthquakes from Poland indicate this method as a useful part of the tectonic and anthropogenic seismicity discrimination workflow.

“…This applies to natural, triggered, and induced seismicity. Hence, we do not discriminate triggered seismicity from induced seismicity, although the former may be initiated by a minor man-made increment of stress [45] or may release larger seismic energy [46]. In geothermal applications, the stress changes are due to the numerous coupled effects of fluid circulation within the reservoir.…”

In order to reach Europe's 2020 and 2050 targets in terms of greenhouse gas emissions, geothermal resources will have to contribute substantially to meeting carbon-free energy needs. However, public opinion may prevent future large-scale application of deep geothermal power plants, because induced seismicity is often perceived as an unsolicited and uncontrollable side effect of geothermal development. In the last decade, significant advances were made in the development of models to forecast induced seismicity, which are either based on catalogues of induced seismicity, on the underlying physical processes, or on a hybrid philosophy. In this paper, we provide a comprehensive overview of the existing approaches applied to geothermal contexts. This overview will outline the advantages and drawbacks of the different approaches, identify the gaps in our understanding, and describe the needs for geothermal observations. Most of the forecasting approaches focus on the stimulation phase of enhanced geothermal systems which are most prone to generate seismic events. Besides the statistical models suited for realtime applications during reservoir stimulation, the physics-based models have the advantage of considering subsurface characteristics and estimating the impact of fluid circulation on the reservoir. Hence, to mitigate induced seismicity during major hydraulic stimulations, application of hybrid methods in a decision support system seems the best available solution. So far, however, little attention has been paid to geochemical effects on the failure process and to production periods. Quantitative modelling of induced seismicity still is a challenging and complex matter. Appropriate resources remain to be invested for the scientific community to continue its research and development efforts to successfully forecast induced seismicity in geothermal fields. This is a prerequisite for making this renewable energy resource sustainable and accessible worldwide.

Impoundment of the Zipingpu reservoir and triggering of the 2008 M_w 7.9 Wenchuan earthquake, China

Impoundment of the Zipingpu reservoir (ZR), China, began in September 2005 and was followed 2.7 years later by the 2008 Mw 7.9 Wenchuan earthquake (WE) rupturing the Longmen Shan Fault (LSF), with its epicenter ~12 km away from the ZR. Based on the poroelastic theory, we employ three‐dimensional finite element models to simulate the evolution of stress and pore pressure due to reservoir impoundment, and its effect on the Coulomb failure stress on the LSF. The results indicate that the reservoir impoundment formed a pore pressure front that slowly propagated through the crust with fluid diffusion. The reservoir loading induced either moderate or no increase of the Coulomb failure stress at the hypocenter prior to the WE. The Coulomb failure stress, however, grew ~9.3–69.1 kPa in the depth range of 1–8 km on the LSF, which may have advanced tectonic loading of the fault system by ~60–450 years. Due to uncertainties of fault geometry and hypocenter location of the WE, it is inconclusive whether impoundment of the ZR directly triggered the WE. However, a small event at the hypocenter could have triggered large rupture elsewhere on fault, where the asperities were weakened by the ZR. The microseismicity around the ZR also showed an expanding pattern from the ZR since its impoundment, likely associated with diffusion of a positive pore pressure pulse. These results suggest a poroelastic triggering effect (even if indirectly) of the WE due to the impoundment of the ZR.
