英文摘要Clear pkikp precursors were observed from the lanzhou ctbto seismic array. we measured their incident angles, arriving azimuths and differential travel times with respect to the pkikp arrivals using array analysis techniques. these measurements allowed us to locate the scatterers that generated the observed precursors. we found that the scatterers are located in the lowermost mantle beneath eastern tibet, which is featured by a high-velocity anomaly based on previous tomographic studies. the high velocity anomaly was interpreted as the slab remnants of the ancient tethys subduction. we thus speculate that the observed scatterers are either related or induced by the subducted slab.
