A new insight into the nature of seasonal variations in coordinate time series of GPS sites located near active faults

这研究在在他们的建模的活跃差错和方法附近定位的 GPS 地点的并列时间系列提供新卓见进季节的变化的性质。每月平均的并列时间系列为在活跃差错交叉区域附近位于的几个并置的 GPS 地点被分析，在到 Amurian 板和圣 Andreas 差错地区的附近的北边界的中央部分的靠近的最近。观察季节的变化被是著名 sine-Gordon 方程的答案之一的 breather 功能最好描述，这被结束。获得的结果建议在这种情况中，季节的变化的来源可以被独居的种类波浪的外观在差错交叉系统引起，它可以是当作承受地质的媒介的压缩扩展的波浪的品质上。基于统计测试，建议模型的适用性的限制被建立了。

This study provides new insights into the nature of seasonal variations in coordinate time series of GPS sites located near active faults and methods of their modeling. Monthly averaged coordinate time series were analyzed for several pairs of collocated GPS sites situated near the active fault intersection area, in close proximity to the central part of the northern boundary of the Amurian plate and the vicinity of the San Andreas Fault zone. It is concluded that the observed seasonal variations are best described by a breather function which is one of the solutions of the well-known sine-Gordon equation. The obtained results suggest that, in this case, the source of seasonal variations may be caused by the appearance of solitary strain waves in the fault intersection system, which may be qualitatively treated as standing waves of compression-extension of the geological medium. Based on statistical testing, the limits of applicability of the suggested model have been established.
