2024年8月19日 · PKP waves are a subset of P-waves (primary waves), which are compressional earthquake waves that travel through the Earth's interior. Specifically, PKP waves are P …

At shorter distances, the first leg is represented by a crustal P wave. PcP reflected from the free surface N-1 times; N is a positive integer. For example PcP2 is PcPPcP. (alt:P z P) P …

2008年12月9日 · Using array analysis on southern California stations we show that these body waves are generated in the ocean from distant storms and propagate deep within the Earth's …

2015年5月2日 · Precursors to the core phase PKP are generated by scattering of seismic energy from heterogeneities in the mantle. Here we examine a large global data set of PKP …

1995年6月10日 · Many core phase data are left out of these constructions, e.g., PKP differential travel times, amplitude ratios, and waveforms. This study is an attempt to utilize this additional …

PKiKP waves (reflections from the inner core) are traceable in this data sample back to 106". The result is consistent with a sharp inner core boundary at 1220km radius.

PKiKP waves (reflections from the inner core) are traceable in this data sample back to 106°. The result is consistent with a sharp inner core boundary at 1220 km radius.

短周期P波主要包括直达P波、地表反射PP波和地核PKP系列震相，PcP、ScP类震相受反射衰减及纵横波转换的影响，能量较弱 (Astiz et al., 1996； Gerstoft et al., 2008； Li et al., 2020). 图 4 …

2015年4月14日 · We apply this method to study the inner core's Western hemisphere beneath South and Central America using paths travelling in the quasi-polar direction between 140 and …

P waves with steeper take‐off angles at the source are either reflected from the core‐mantle boundary (PcP) or refracted into the core (PKP). The refracted PKP waves have a relatively …
