Summary:
How to design a seismic network for monitoring seismicity in the vicinity of a reservoir and achieve the highest sensitivity and accuracy? What is the smallest earthquake you can detect with a given seismic network? How to design a seismic network when you want to distinguish between induced and natural earthquake? Numerical simulations are done to answer these questions. Simulation results are presented as depth slices of the minimum detectable earthquake magnitude or as depth slices of the accuracy of an earthquake location. Simulations with various network geometries helped us to draw simple rules for the optimal surface monitoring network.
