构造型地震是现代断层突发性错动产物。在强震孕育与破裂过程中,不仅释放巨大应变能量,而且在断层活动地段伴随着热效应,并引起岩石和土壤中水产生汽化与低空气体电离作用,从而诱发各种波段的地光现象(包括热红外光谱异常)。在中强地震前,随着断层放气与低空气体电离作用增强,将导致热红外异常更加明显。因此应用卫星热红外异常判别技术,可以在宏观尺度上,快速捕获震前热红外异常信息。作者应用这一新技术,结合断层的活动性,较好地预测了我国一些中强地震,并取得一定经验。它表明该方法是一种预测地震的新途径。

Tectonical earthquakes are the results of abrupt fault slipping. In fracturing process, Strong earthquakes not only release huge strain energy, and produce thermal effects on active fault segments which make water stored in rock and soil evaporation and low air electrolytic dissociation. At the same time, the effects induce earth lightning on several wave segments including thermal infrared spectrum anomaly. Ahead of intermediate and strong earthquakes, it causes thermal infrared anomaly more evident with strengthening of fault gas releasing and low air electrolytic dissociation. So using interpretation technique of satellite thermal anomaly, we can quickly catch thermal infrared anomaly signal in large scale ahead of earthquake. Combining this new technique with the fault activity, we predicted some of intermediate and strong earthquakes in China with good reliability and attained some experience. It shows that the method is a new way to predicting earthquake.
