地倾斜变化作为一种地震前兆现象,在国内外已被人们广泛重视,因此,观测和研究地震前地倾斜的变化,在地震预报探索中有其重要的意义。 我国地震系统进行地倾斜观测和研究已有十多年的历史,新疆也有15个台站曾先后开展过此项观测,获得了大量的资料,也曾试用于地震预报的探索工作,但是,实践证明震前的地倾斜变化是十分复杂的,影响因素很多。 本文试图以实际记录到的若干震前地倾斜信息,研究新疆地区倾斜前兆的某些特征。
As a kind of seismic precursory phenomenon, geodetic tilt change has been widely considered both at home and abroad. Therefore, observing and studying the change of dip before the earthquake is of great significance in the earthquake prediction exploration. China’s seismic system has been observed and studied for more than ten years. Fifteen stations in Xinjiang have successively carried out this observation and acquired a large amount of data. They have also tried the exploration of earthquake prediction. However, practice It proves that the change of ground tilt before earthquakes is very complicated and has many influencing factors. This paper attempts to study some of the characteristics of tilt precursors in Xinjiang based on actually recorded pre-earthquake tilt information.
