WebJan 1, 2024 · Comparison of combined 2D SH full waveform inversion strategies. In order to fit the dominant Love-waveform and first arrival waveform, we test different combinations of the “classical” FWI strategies mentioned in the last paragraph. The FWI result of one part is the initial model for the next. 5.1. WebDec 19, 2013 · For moderate events (M6 or weaker), SH waveform is typically noisier than P waves, and that is probably why some studies only use P waves for tCAP inversions (Zeng et al. 2013). Here, we exclude SH waves in the inversion process and find that the centroid depth for the case P wave only is 12.0 km, only 0.5 km different from the case of using …

Here both P and SH waveform modeling show a consistent feature of a transitional 660 with thickness ∼44±6 km, which is 6 km thinner than that of ... WebJun 27, 2006 · An average crustal P velocity of 6.2–6.3 km/s is obtained for a crustal thickness of 65 km while the P velocity of the uppermost mantle is 8.1 km/s. The upper layer of the model is further fine-tuned by obtaining the best synthetic SH waveform match to an observed waveform for a well-located event. psychiatrist\\u0027s bk
