The volumetric changes in the underground (e.g., the injection salt water disposal, hydraulic fracturing, mining, gas or rock extraction) can trigger or induce felt earthquakes. Induced seismicity can be very complex, but limitations on induced seismic events may be estimated as the injected energy is known and the affected volume is limited. The size of the largest event is also determined by how much of the energy is released through weaker events. We offer a service to determine the possible magnitude of the potentially largest induced seismic event caused by a volumetric change (injection or hydraulic fracturing).
Our model determining the possible magnitude of a potentially largest induced seismic event is derived from the Gutenberg-Richter law and the estimate of a total released seismic moment. The main input parameters are volume change in the underground (injected volume) and a type of the stimulation.
