Speaker: Dario Baturan, Nanometrics

Earthquakes can be induced by human activities such as mining, reservoir or dam impoundment, geothermal reservoir stimulation, wastewater injection, hydraulic fracturing or CO2 sequestration. Such events are predominantly small in magnitude, and are rarely felt locally or detected regionally. In certain areas of Canada and the US, the rates of seismicity characterized as induced or triggered have been increasing over the past several years; most concerning is the increase in the number and frequency of potentially damaging magnitude 3.0+ events. In Oklahoma, for example, the USGS reported more than 500 magnitude three or larger events in 2014, compared to only 53 between 1970 and 2005. As a result, states such as Oklahoma, Texas, Colorado, Ohio, Arkansas, California and others are investing an increasing amount of attention and resources into the issue. Responses have included closer investigation into specific events, requiring more extensive monitoring, developing regulations or even area-wide moratoriums in an attempt to mitigate risks associated with induced seismicity. 

Such policies and regulations have contributed to an increased number of private and shared seismic arrays as well as the densification of existing public networks to help better understand the attributes of induced seismicity. This has resulted in an unprecedented volume of seismic data, which has been used by operators, regulators and researchers to assist in identification of geological structures, understanding of the correlation between operational parameters and observed seismicity, investigation of source attributes of induced earthquakes, and derivation of regional attenuation relationships required for accurate magnitude calculations and seismic hazard estimates. The findings of such studies are used to guide operators and regulators in accurately assessing the risks associated with induced seismicity and developing effective risk mitigation strategies. 

In this talk, I present key insights gained from three years of doing induced seismic monitoring (ISM) as well as results of the research done with ISM-generated seismic data. First, I discuss the key characteristics of observed induced seismicity and the benefits of high-quality ISM data sets with emphasis on how their value largely depends on appropriate instrument selection, sound seismic network design and data processing techniques utilized. Using examples from recent research studies, I illustrate the key role of robust modeling of regional source, attenuation and site attributes on the accuracy of reported event magnitudes, ground motion estimation and induced seismicity hazard assessment. Finally, acknowledging that the ultimate goal of ISM networks is in assisting operators to manage induced seismic risk, I share some examples of how ISM data products can be potentially used to measure the effectiveness of implemented risk mitigation protocols in near-real time.
