Fig. 4From: Small-scale scattering heterogeneities beneath the northern Tien Shan from the teleseismic P wavefieldVespagrams of the original waveforms for Event 2010.02.15.21.51. A 3rd-root stacking is applied to the waveforms. The two white crosses denote the theoretical slowness values of P and PcP predicted by the AK135 model, respectively. Note that behind the strong direct P-wave energy, no other clear coherent arrivals are found within the analyzed time window (up to 25 s following the P arrival)Back to article page
