Hydraulic fracturing is the prime cause of a small percentage of the earth seismicity (having low magnitudes) observed in the USA. The largest hydraulic fracturing prompted earthquakes up to these dates are two M 4.4 earthquakes in central west Alberta and northeast British Columbia in Canada (British Columbia Oil and Gas Commission, 2014).1 Introduction. Injection-induced seismicity has been known since the earthquakes triggered at the Rocky Mountain Arsenal [Healy et al., 1968] and the subsequent experiment in earthquake control at Rangely [Raleigh et al., 1976].More recently, the subject has gained widespread attention due to earthquakes apparently triggered by waste water injection [e.g., Horton, 2012; Kim, 2013; Keranen et ...

Induced Seismicity Since 2008: A Rapid Rise in Rate, and a Rapid Rise in Research. A rapid increase in the rate of induced seismicity since 2008, including numerous felt earthquakes and several moderate-sized earthquakes ( Figures 2 and 3 ), abruptly raised the impact and public visibility of anthropogenic seismicity.

Mitigating hydraulic fracturing-induced seismicity (HF-IS) poses a challenge for shale gas companies and regulators alike.

Induced Seismicity. Induced seismicity is typically defined as smaller magnitude earthquakes (3.0 or below) that are caused by changes of the stress and strain in the earth due to human activity. Although most induced earthquakes are smaller magnitude, there are several induced earthquakes that are a magnitude 4.0 or greater.The question we pose for induced seismicity is whether the largest observed magnitudes are consistent with the sampling statistics of the Gutenberg-Richter MFD, given the total number of induced earthquakes at each site. We will refer to this as the “sample size” hypothesis for maximum magnitude.induced seismicity in EGS projects.
