Statistical Evaluation of Induced Seismicity at the Karkheh Dam, Iran
Karkheh Dam is the largest dam in Iran with a capacity of about 7.4×109 cubic meters and height of 127 meters. Since the first impoundment, increasing in seismic activity in the dam area has been observed that indicates the possible occurrence of reservoir-induced seismicity (RIS).In the present work, a preliminary evaluation is conducted firstly in order to investigate these observations. Base...
متن کاملPreliminary evaluation of induced seismicity at the Karkheh dam site in southwest Iran
The reservoir-induced seismicity (RIS) at the Karkheh dam site with a reservoir capacity of about 7.4x109 meters is investigated. Based on the assessment of the seismicity of the dam site in equal time periods before and after reservoir impoundment, it was found that the number of earthquakes have been tripled after impoundment, while their magnitudes and focal depths become smaller. The averag...
متن کاملFluid‐induced seismicity: comparison of rate‐ and state‐ and critical pressure theory
Background Gaucher et al. (2015) provide an overview on published methods employed for modelling induced seismicity in geothermal reservoirs. Here I focus exclusively on the rateand state-dependent theory of Dieterich (1994), further referred to as RST for modelling fluid injection induced seismicity. For simplicity, I consider the case of fluid injection at the origin in a medium with isotropi...
متن کاملOn the Nature of Reservoir-induced Seismicity
In most cases of reservoir-induced seismicity, seismicity follows the impoundment, large lake-level changes, or filling at a later time above the highest water level achieved until then. We classify this as initial seismicity. This ‘‘initial seismicity’’ is ascribable to the coupled poroelastic response of the reservoir to initial filling or water level changes. It is characterized by an increa...
متن کاملFluid-injection induced seismicity in the Cooper Basin (Australia): spatial, temporal, and energy characteristics
Induced seismicity has been recognized as a concern in subsurface industrial operation, and particularly at fluid-injection sites in major oil and gas exploitation plays, where hydraulic stimulations are conducted to increase rock permeability. Induced seismicity occurs also in Enhanced Geothermal Systems (EGS), where hydraulic fracturing is used to accelerate heat extraction from the rock. If ...
متن کاملSeasonal variations of seismicity and geodetic strain in the Himalaya induced by surface hydrology
One way to probe earthquake nucleation processes and the relation between stress buildup and seismicity is to analyze the sensitivity of seismicity to stress perturbations. Here, we report evidence for seasonal strain and stress (~2–4 kPa) variations in the Nepal Himalaya, induced by water storage variations which correlate with seasonal variations of seismicity. The seismicity rate is twice as...
