Shown are (a, b) the spectrograms of stack PcP and PKiKP at KKA from Event1. (c, d) are the same as (a, b), but for the array KURA from Event1. (e, f) are the spectrum results of PcP and PKiKP respectively for the array KURA from Event2. (g, h) are the spectrum results for the array XLA from Event2. The time zero is the PcP and PKiKP arrival time. KKA, KURA, and XLA are the Karatau Array, Kurchatov-Cross Array, and XL temporary seismic array, respectively.
