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!
