前言本文讨论1976年唐山大震前一年左右时间孕震及发震的过程,其中包括震中区地壳形变及其导致的前兆变化和地壳下部物质的运动进程,不讨论震时的地壳断裂情况,只讨论破裂前的孕震过程。作者在文献[1]内用地形变、地下水异常和测震学指标的变化等前兆资料,反演和充分地论证了国内外七级以上大地震,其中包括唐山地震前震中区及其外围地面存在一个有规律性的形变,即存在一个波浪状运动。为了更直观地讨论唐山地震的孕震过
Preface This paper discusses the processes of earthquakes and earthquakes about a year or so before the Tangshan earthquake in 1976, including the crustal deformation in the epicenter area, the precursor changes and the movement of the material beneath the crust, without discussing the crustal faults in the epicenter, Only discuss the process of seismogenic before rupture. In [1], the authors inverstigated and fully demonstrated that earthquakes of over seven magnitude at home and abroad, including the epicenter area before the Tangshan earthquake and the outer surface of the surrounding area, were retrieved from precursory data such as the deformation of the groundwater, groundwater anomalies and the changes of seismological indexes A regular deformation, that is, there is a wavy movement. In order to more intuitively discuss the earthquake in Tangshan earthquake
