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.

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!

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.

Finally, a subpage dedicated to MSATSI package is ready!
