摘要

本文对印度阿格拉站2013年4月的TEC观测数据进行了分析。纬度。27.2°N,长。为了检验2013年4月16日发生在巴基斯坦-伊朗边境地区的M = 7.8级地震的影响。利用s统计准则对TEC数据进行处理,找出TEC数据的异常变化。我们还研究了夏威夷NPM(21.42°N, 158°W)的VLF传播信号,该信号是在这次地震和太阳耀斑的同一台站(Agra站)监测的。采用夜间波动法对地震当日(2013年4月11-21日)±5天的VLF数据进行分析。在事件发生前1-9天的TEC数据中发现了异常的增强和消耗。

Anomalous Variations of Ionosphere Associated with the Strong Earthquake at Pakistan-Iran Border at a Low Latitude Station Agra, India
In this paper, we analyze the TEC data for April 2013 observed at Agra station, India (geogr. lat. 27.2° N, long. 78° E) to examine the effect of earthquake of magnitude M = 7.8 which occurred on 16 April 2013 at Pakistan–Iran border region. We process the TEC data using the s statistical criterion to find out anomalous variation in TEC data. We also study the VLF propagation signal from NPM, Hawaii (21.42° N, 158° W), which is monitored at the same station (Agra station) in the light of this earthquake as well as solar flares. The nighttime fluctuation method is used to analyze the VLF data for the period of ±5 days from the day of earthquake (11–21 April 2013). The anomalous enhancements and depletions are found in TEC data on 1–9 days before the occurrence of event.
