Abstract
It was reported that a new find on sub-layer movement in the large-scale stratum had been observed. Earthquakes with different division magnitude can represent movement of sub-layer with different thickness. Earthquakes with different division magnitude can display the different characteristic of tectonics, in a same region and same time period. A direct evidence of movement, synchronal movement in vertical direction, in the as large-scale stratum has been reported in this paper. Stratum scale can be large as up to several thousand kilometers, as in a continent dimension. Events with strong tremble of sub-layer movement have been analyzed, which were recorded by stations with seismograph of super long period (300 〜3 000 s) . A certain relationship between events with strong tremble recoded by Golmud Station in November, 2001 and earthquake occurred at west of Kunlun Mountain Pass, nearby the station, on 2001 - 11 - 14, has been found. That information is very important for earthquake prediction research and geodynamic recognition.
