Summary

CSEM_Iberia is the Iberian (Western Mediterranean) part of the Collaborative Seismic Earth Model (CSEM, Fichtner et al., 2018).

Description

Name CSEM_Iberia
Version 2019.12.01 (December 1, 2019)
Title Iberian part of the Collaborative Seismic Earth Model (CSEM)
Type 3-D Tomography Earth Model
Sub Type SH velocity, SV velocity
Year 2019
 
Short Description   CSEM_Iberia (V. 2019.12.01) is the Iberian (Western Mediterranean) part of the Collaborative Seismic Earth Model (CSEM, Fichtner et al., 2018). It has been constructed using multi-scale full seismic waveform inversion, combining spectral-element waveform modelling and adjoint techniques, as described in Fichtner et al. (2006,2009). This submodel has been extracted from the variable-parameterisation CSEM onto a regular grid, readable by EMC tools.
 
While having regional contributions from various sub-inversions, the structure in this model is dominated by the full-waveforms inversion described in Fichtner et al. (2013) and Fichtner & Villasenor (2015).
