Adjoint centroid-moment tensor inversions
S U M M A R Y We determine centroid-moment tensor (CMT) solutions by minimizing waveform differences between observed and simulated seismograms based on an adjoint method. Synthetic seismograms and Fréchet derivatives are calculated based on a spectral-element method. The non-linear adjoint CMT inversion algorithm requires three simulations for each iteration: one ‘forward’ simulation to obtain...
متن کاملLocating earthquakes with surface waves and centroid moment tensor estimation
[1] Traditionally, P wave arrival times have been used to locate regional earthquakes. In contrast, the travel times of surface waves dependent on source excitation and the source parameters and depth must be determined independently. Thus surface wave path delays need to be known before such data can be used for location. These delays can be estimated from previous earthquakes using the cut-an...
متن کاملGlobal slab deformation and centroid moment tensor constraints on viscosity
[1] We analyze moment tensor solutions from deep subduction zone earthquakes to determine global slab deformation patterns. Inferred strain rates are compared to predicted deformation patterns from fluid models to help constrain the first‐order radial and lateral viscosity structure of the Earth. While all slabs that reach the lower mantle are compressed at their tip, intermediate depth pattern...
متن کاملStatistics A exam solutions ( 2003 - 2004 )
I may have committed a number of errors in writing these solutions, but they should be ne for the most part.Use at your own risk! Statistics May 2003 Problem 1 a) g(p) is U-estimable i n x=0 h(x) n x p x (1 − p) n−x = g(p). The left hand side is a sum of polynomial of degree ≤ n, and hence the right hand side has to be a polynomial of degree ≤ n. b) From section a) we know that h(x) has to be s...
متن کاملIdentifying Isotropic Events Using a Regional Moment Tensor Inversion
The deviatoric and isotropic source components for 17 explosions at the Nevada Test Site, as well as 12 earthquakes and 3 collapses in the surrounding region of the western US, are calculated using a regional time-domain full waveform inversion for the complete moment tensor. The events separate into specific populations according to their deviation from a pure double-couple and ratio of isotro...
