Induced seismicity is a well-known phenomenon, although events are rarely large enough to be either felt locally or detected by regional seismic networks
Many regulatory bodies have mandated induced seismicity monitoring (ISM) programs that involve the deployment of real-time seismic networks in the vicinity of operations.
Induced seismicity is a much-discussed topic, but how to best monitor for induced seismicity often generates more questions than answers:
How many stations are needed to meet the monitoring mandate and what should be their geographical distribution?
How many stations could be inoperative before the network does not meet its monitoring mandate?
With a number of sensing technologies to choose from, including seismometers, accelerometers and geophones, which one provides the best combination of self-noise, clip level and frequency response to cover the seismic event magnitude and epicentral distance range?
As most current “traffic light” protocol thresholds are based on magnitudes, which magnitude scale should be used?
With our decades of experience, we have the knowledge and expertise to provide the best, most comprehensive and effective induced seismicity monitoring solutions.
We provide comprehensive data sets you can trust
Data from public networks do not have the resolution or accuracy required by today’s operators. It’s important to design ISM networks to provide the richest possible data sets as these data sets can offer benefits beyond basic regulatory compliance. We can provide comprehensive data sets you can trust to drive operational decisions.
The data can and have been used by operators 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 can guide operators and regulators in accurately assessing the risks associated with induced seismicity and developing effective risk mitigation strategies.
How effective is your risk mitigation strategy?
A rich seismicity catalogue generated by a properly designed ISM network can provide some insights into the effectiveness of induced seismicity risk mitigation strategies. A quantitative measure of seismic risk includes assessment of potential hazards and their social, environmental, and economic impacts. Risk mitigation strategies can be applied to both hazard and exposure components. Seismic hazard, referring to the level of ground shaking that may occur at a given probability, can be reduced by minimizing the likelihood of inducing large events.
Manage risk in real time with our turnkey seismic monitoring solutions
We’re on the leading edge of technical innovation and evolving industry demands. We were the first to introduce regional traffic light protocol monitoring in Canada, and we work closely with industry groups and researchers to stay abreast of regulatory discussions and ensure our systems are ready for any potential changes in regulations, including the requirement to monitor ground motions.
Our fully autonomous turnkey monitoring solution uses our proprietary broadband arrays with the latest state-of-the-art event detection, communication and data processing technology.
Athena Data Management System
The Athena Data Management System is included as part of our seismic monitoring solution, allowing you to browse up-to-date event catalogues, view all recorded event source parameters and waveforms, select and download sections of the catalogue, plot frequency/magnitude relationships for event clusters, examine maps showing distribution of ground motions from each recorded event and track network seismicity rate to manage risks associated with induced seismicity in real time.
Meeting your monitoring mandate, right from the start
We’ll manage the network design, installation, commissioning, data acquisition and processing to enable you to satisfy your technical requirements and meet or exceed monitoring regulations, right out of the gate.
