TL;DR: Geophysical evidence of fluids migrating into the creeping section of the San Andreas fault that seem to originate in the region of the uppermost mantle that also stimulates tremor is presented, and evidence that along-strike variations in tremor activity and amplitude are related to strength variations in the lower crust and upper mantle is presented.

TL;DR: In this article, the authors examined the magnetotelluric (MT) impedance tensor from the viewpoint of polarization states of the electric and magnetic field and found that the columns of the MT tensor will be non-orthogonal, i.e. their linear polarization is manifested in a common phase for the elements of each column of the tensor and is a well known indication of galvanic distortion.

TL;DR: In this article, magnetotelluric (MT) data from 66 sites along a 45 km-long profile across the San Andreas Fault (SAF) were inverted to obtain the 2-D electrical resistivity structure of the crust near the SDF Observatory at Depth (SAfOD) and the most intriguing feature of the resistivity model is a steeply dipping upper crustal high-conductivity zone flanking the seismically defined SAF to the NE, that widens into the lower crust and appears to be connected to a broad conductivity anomaly in the upper mantle

TL;DR: In this article, magnetotelluric (MT) images have revealed several prominent electrical conductivity anomalies at the San Andreas Fault which have been attributed to the presence of saline fluids within porosity networks and which are associated with tectonic processes.

TL;DR: In this article, the Arava/Araba Fault (AF) segment between the Dead Sea and the Red Sea is studied using a multidisciplinary and multiscale approach from the mu m to the plate tectonic scale.
