Mapping seismic anisotropy using harmonic decomposition of receiver functions: An application to Northern Apennines, Italy
[1] Isotropic and anisotropic seismic structures across the Northern Apennines (Italy) subduction zone are imaged using a new method for the analysis of teleseismic receiver functions (RFs). More than 13,000 P‐wave coda of teleseismic records from the 2003–2007 Retreating‐Trench, Extension, and Accretion Tectonics (RETREAT) experiment are used to provide new insights into a peculiar subduction ...

More than 13,000 P-wave coda of teleseismic records 10 from the 2003-2007 RETREAT experiment are able to reveal new insights 11 into a peculiar subduction zone which develops at the convergent margin of 12 two...
متن کاملCrustal anisotropy across northern Japan from receiver functions
Northern Japan is a tectonically active area, with the presence of several volcanoes, and with frequent earthquakes among which the destructive Mw = 8.9-9.0 Tohoku-oki occurred on 11 March 2011. Tectonic activity leaves an imprint on the crustal structures, on both the upper and the lower layers. To investigate the crust in northern Japan, we construct a receiver function data set using telese...
متن کامل33 Seismic Imaging of the San Andreas Fault in Northern California using Receiver Functions
Scattering of teleseismic body waves is conventionally used to investigate crustal and mantle structure using the so-called “receiver function” technique. This approach makes use of the fact that teleseismic events have nearvertical incidence upon horizontally layered structure, ensuring minimum phase, and assumes that source-time functions can be approximated by energy on the P component of mo...
متن کاملCrustal fracturing and presence of fluid as revealed by seismic anisotropy: case histories from seismogenic areas in the Apennines (Italy)
An automatic analysis code, Anisomat+, was developed, tested and improved to calculate anisotropic parameters: fast polarization direction and delay time. Anisomat+ was applied on data coming from three zones of the Apennines in Italy. For each area, anisotropic parameters have been interpreted to determine the fracture and stress field taking into account the geological and structural settings...
