  汶川地震、海地地震和智利地震是近年来发生的比较严重的三大地震,本文对这三个地震震前等离子体出现的一些异常现象进行探讨和分析,对可能与地震有关的异常现象进行了总结。本文依据前人研究经验,选取了:震前10天、地震当天及震后几天的时间范围、震中周围2000km内的空间范围、Kp指数小于4o及空间环境较平稳的夜间地磁环境以及电子密度(Ne)、电子温度(Te)、离子数密度(Ni:包括H+、O+、He+的数密度)、离子温度(Ti)等。主要采用时间演化特征提取、Ti长时间序列异常提取以及多参量轨道对比等方法进行数据的分析和处理,综合地震前后空间等离子体参量的处理和统计分析结果,得出如下结论:(1)地震的临震异常现象明显。
