许多强烈地震都伴生有发光现象,称为地光.国内外大量震例表明,地光形式多样,姿态万千.近年来,在一些强震前后发现有一种可能是因为低空大气受激发光而产生的地光现象.研究其特征和成因,对摸清地震孕育和发展的地球物理变化过程,将是有意义的.1976年7月28日唐山7.8级地震后,当日18时又发生滦县7.1级地震.在震中附近的滦县商家林公社赵各庄大队数百名社员,在中学校长的带领下转移至高百余米凤凰山顶,徹夜未眠,目睹了距离于米之远的发震构造——滦县西断裂附近的近百起地光事件.当天正值农历初一是阴天间小雨,一片漆黑.在多数为耀眼而短瞬即逝的条带状地光中,偶见一种“激发光”.当晚24时左右,在发震构造附近先出现一条闪光,接着在其附近的王家山、凤凰山及其周围的村庄如赵各庄、粟
Many strong earthquakes are associated with luminescence, known as the light.A large number of earthquakes at home and abroad show that there are many forms of light and thousands of gestures.In recent years, some of the strong earthquakes may have been discovered before and after the stimulation of low-level atmospheric light The study of its characteristics and causes, it is significant to find out the geophysical change process of the gestation and development of earthquakes.After the MS 7.6 Tangshan earthquake of 7.8 on July 28, 1976, Luan County 7.1 magnitude earthquake in the vicinity of the epicenter Luanxian business Lin commune Zhaogezhuang brigade hundreds of members, under the leadership of secondary school principals in the transfer to a high of more than 100 meters Fenghuang Peak, sleepless nights, saw the distance from the far earthquake Tectonic - Luanxian West near the fault of nearly a hundred light events that day coincided with the Lunar New Year is cloudy and rainy, darkness in most of the bright and fleeting ribbon of light, and occasionally see An “excitation light.” At about 24 o’clock that night, a flash occurred near the seismogenic structure, followed by the nearby Wangjiashan, Fenghuangshan and surrounding villages such as Zhaogezhuang and Su
