Abstract

The paper presents atmospheric coupling physics through identifying a few significant features imprinted on the ionosphere by certain unique seismic environments when a number of successive cluster of earthquakes ranging from 7.1 to 8.2 magnitudes occurred within about two weeks period, over the East-West Pacific zone covering 150° E to 70° W. Amongst the cases considered here are earthquakes of Chile Apr. 1, 2014 (M = 8.2) and Apr. 3, 2014 (M = 7.7), New Guinea Apr. 11, 2014 (M = 7.1) and Solomon Islands 13.04.2014 (M = 7.6). The main data source for the study is Global TEC with supplementary inputs from GPS observations taken at Guwahati (26° N, 92° E), an Appleton anomaly crest region. A few EQ events with epicenters in and around this anomaly zone are also taken in the study to focus on the seismic induced density features like Earthquake time Equatorial Anomaly (EEA) and Earthquake time Equatorial Anomaly Crest (EEAC) developed over the belt. Such anomalous modifications in TEC resulting to growths of EEA and EEAC covering Solomon Islands—New Guinea extending up to Chile along the fault lines for more than a month, are significant observations brought out in the paper. The GPS TEC data from Gauhati University are utilized in identifying the epicentre position through anomalous appearance of satellites beyond the Line Of Sight (LOS) observation. Finally, the seasonal role on enhancing the seismic induced E-field coupled by mutual interactive EQ preparatory effects of the three major events as well as in enhancement of EQ time radon emission through fault is invoked in explanation to the anomalous density features.

连续强震群在电离层上的摄动特征：大气耦合动力学的作用

摘要

本文通过识别东西太平洋区域覆盖的东西在大约两周内发生了一系列7.1至8.2级的一系列连续地震，从而确定了某些独特的地震环境在电离层上留下的一些重要特征，从而提出了大气耦合物理学。 150°E到70°W。这里考虑的案例是智利的地震（2014年4月1日（M = 8.2）和2014年4月3日（M = 7.7），新几内亚2014年4月11日（M = 7.1） ）和所罗门群岛2014年4月13日（M = 7.6）。这项研究的主要数据来源是全球TEC，它是在Appleton异常波峰地区Guwahati（26°N，92°E）进行的GPS观测得到的补充输入。在这项研究中，还采取了一些震中在该异常带及其周围的情商事件，以关注地震诱发的密度特征，如在该带上发育的地震时间赤道异常（EEA）和地震时间赤道异常波峰（EEAC）。TEC中的这种异常变化导致EEA和EEAC在所罗门群岛（新几内亚）沿断层线延伸到智利长达一个多月的增长，是本文的重要发现。来自高哈蒂大学的GPS TEC数据用于通过视线（LOS）观测范围以外的卫星异常出现来确定震中位置。最后，
