On acoustic emissions, moment tensors and anisotropy

We have published a paper related to the analysis of seismic moment tensors of acoustic emission data with a special focus on effects of rock anisotropy on resulting moment tensors.

Two new papers on Induced Seismicity

We just published two new papers related to analysis of induced seismicity. First paper discusses the effects of long-term fluid injection on induced seismicity parameters and maximum likely magnitude at The Geysers geothermal field. In the second paper we perform the statistical analysis of couple of induced seismicity datasets and discuss the violations of Gutenberg-Richter relation in anthropocentric seismicity.
