b value

A paper on spatial distribution of b-value in North Anatolian Fault Zone

The paper on spatial variations of seismic Gutenberg-Richter b-value along the North Anatolian Fault Zone have been recently published in the Tectonophysics.

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.

Article on moment tensors and b values from acoustic emissions

Finally, the paper on seismic moment tensors and b-values calculated for acoustic emissions has been published in Geophysical Research Letters. Here is the link and reference to the paper:
