Sub-layer Movement in the Large-scale Stratum
Xu Shaoxie
报告了观察到大尺度地层内分层运动的新发现,以及大尺度层块活动的直接证据——大尺度地层垂向同步运动,其层块的尺度可大到数千公里洲际尺度。分析了我国超长周期(360~3000s)地震监测台站记录中的层块活动局域性高强颤振事件。发现格尔木台(2001年11月份)记录到的高强颤振事件与发生在其附近(2001.11.14)昆仑山口西M8.1大震有一定关系。这些信息对于探索地震预测,以及认识大地构造动力具有重要意义。
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.
