... widely used around the world at different types of mines [1,2]. A microseismic monitoring system normally consists of a network of individual geophones that are distributed at isolated locations around a mining area, sparsely spaced at 50–200 m.

Results show that for a fixed length of hydraulic fracture, the first events in time occur near the crack tip region where the Coulomb stress changes are positive due to elastic stress perturbations. The pore pressure diffusion subsequently leads to microseismic events near the fracture face...

... Abstract: Microseismic events are commonly recorded during hydraulic fracturing experiments. In microseismic interpretations, each event is often regarded as causally independent and uncorrelated to neighboring ones. In reality, both the rock deformation (static stresses) and transient wave...
