平均海平面变化与地震的关系——海城地震前的平均海平面变化
A STUDY OF THE RELATION BETWEEN VARIATIONS OF THE MEAN LEVEL AND EARTHQUAKE OCCURRENCE——THE VARIATION OF MEAN SEA LEVEL BEFORE THE 1975 HAICHENG EARTHQUAKE
-
摘要: 对多年来在我国渤海沿岸五个验潮站的海平面连续记录资料进行了各种改正和处理之后, 发现1975年海城地震前平均海平面出现大范围稳定持续的上升趋势, 震中区附近该平面的变化更为显著, 并表现为突发性的变化.但1969年在同区发生的渤海大地震之前, 则平均海平面经历了长趋势的下降.Abstract: This paper deals with the investigation of the data of variation of sea level continuously recorded during many years by 5 tidal stations located along the coast of the Gulf of Bohai. After processing the data and making various corrections, it was found that before the Haicheng Earthquake of 1975 the average sea level showed a tendency of steady rise within a broad area. For the recording stations closer to the epicenter of the earthquake, the variation of the sea level became more conspicuous and abrupt. However, before the Bohai Earthquake, occurred in the Gulf of Bohai in 1969, the mean sea level was lowered for a long period of time.
