Abstract

The study analyzes the coordinate time series of five permanent International GNSS Service (IGS) stations located in New Zealand. It also considers their annual movement from 2009 to 2018. The raw data in the form of Receiver Independence Exchange (RINEX) files were taken from IGS database and processes by means of online processing service AUSPOS. Using coordinate time series, horizontal and vertical displacement rates were calculated covering the ten-year study period. According to the results, stations located at the North Island of New Zealand revealed an uplift of 31-32 mm/yr. At the same time, stations placed on the South Island showed the 21-22 mm/yr of positive vertical displacement. Regarding the horizontal displacements, their rates increase in North-South direction over the study region. In particular, two stations of North Island, located at the North-Western part, appeared in 24-25 mm/yr displacement, and one station at the Southern part of North Island showed the 35 mm/yr displacement rate. Stations, established at South Island, showed the horizontal displacement rates of 41-56 mm/yr. This research confirms the main contribution made to the field of crustal deformation studies, including the updated values of displacements along with their directions over the recent years. The results of this study can be used for further geodynamics investigations as well as for finding the most likely earthquake locations of the current study area.

该研究分析了位于新西兰的五个永久国际GNSS服务(IGS)站的坐标时间序列。它还考虑了他们从2009年到2018年的年度运动。接收方独立交换(RINEX)文件形式的原始数据取自IGS数据库,并通过在线处理服务AUSPOS进行处理。利用坐标时间序列,计算了十年研究期间的水平和垂直位移率。根据结果,位于新西兰北岛的台站显示了31-32 mm/年的隆升。同时,位于南岛的台站显示出21-22毫米/年的正垂直位移。水平位移的速率在南北方向上呈增加趋势。其中,北岛西北部的2个台站出现了24 ~ 25 mm/yr的位移,北岛南部的1个台站出现了35 mm/yr的位移。在南岛建立的气象站显示水平位移率为41-56毫米/年。这项研究证实了近年来对地壳形变研究领域的主要贡献,包括对位移值及其方向的更新。这项研究的结果可以用于进一步的地球动力学调查,以及寻找当前研究区域最可能发生地震的位置。
