Teleseismic events

WebNov 19, 2024 · In addition to ambient noise cross-correlations, we correlate time windows (45 min long) that include strong teleseismic events using the two-station method (e.g. Meier et al., 2004; Boschi et al., 2013; Tonegawa et al., 2024). We only use station pairs for which the stations' azimuth equals the great circle from the event to within ±7 ∘ ... WebThe kinematic source rupture process of the 2016 Meinong earthquake (Mw = 6.4) in Taiwan was derived from apparent source time functions retrieved from teleseismic S-waves by using a refined homomorphic deconvolution method. The total duration of the rupture process was approximately 15 s, and one slip-concentrated area can be represented as …
