Extended Data Fig. 3: Dimensionality analysis using phase tensor.
From: Forearc seismogenesis in a weakly coupled subduction zone influenced by slab mantle fluids
Dimensionality analysis for the profile data using phase tensor. (a) Rose histogram showing phase tensor geoelectric strike angles for raw, un- edited dataset at all frequencies indicating no coherent strike direction. (b) Rose histogram showing phase tensor geoelectric strike angles for edited dataset at all frequencies indicating coherent strike direction of approximately 75°E of N. (c) Histogram of phase tensor skew angles for un-edited data at all frequencies with long tails to ±80°. (d) Histogram of phase tensor skew angles for edited data set at all frequencies with tighter distribution near 0°.
