New paper on fault instability at The Geysers

We published a new paper in Journal of Geophysical Research: Solid Earth that discusses the influence of long-term fluid injection on fault reactivation potential at The Geysers geothermal field, California.

Paper on the influence of pore pressure changes on stress tensor inversion parameters

Another paper! This time we discuss the influence of temporal changes in pore pressure on the results of stress tensor inversion from focal mechanisms, with the special focus on stress shape ratio coefficient. There is also a neat presentation of the effects using the data from The Geysers geothermal field. The paper has been published in Geophysical Research Letters. Have fun!

Article on the stress tensor inversion package MSATSI

Finally, our paper on stress tensor inversion package MSATSI has been published in the recent issue of Seismological Research Letters! The package has an official page at MSATSI website at GFZ (short version), but the extensive documentation and multiple examples you can find at this website.
