The earthquake made the waste dump of Tianjin Soda Plant, located in the area of 8 degrees ofearthquake intensity, liquefied and flowed dramatically. Its flow volume totaled about 6 million of Cubic meters and mode damage to person and properties. It also caused surface loosening, cracking and collapsing partly on some slopes of northern hills and low mountains located in the area of 7 degrees of earthquake intensity, so that the development of mudflows in the area was slighlty intensified.
Other Abstract1976年7月28日凌晨3时42分唐山丰南发生了7.8级强烈地震,同日18时45分又在相距红80公里的迁安县野鸡坨附近发生了7.级强烈余震。这次地震发生在人口密集的平原工业区,烈度高,破坏范围广,损失严重。震中烈度为Ⅵ,Ⅶ度及其以上烈度区面积达3.33万平方公里。从地域上看,唐山北部低山丘陵区和南部滨海平原以及天津市为Ⅶ度区,唐山市及其周围冲积平原属Ⅷ度以上烈度区。为了探讨强烈地震对震区泥石流现象的影响,作者于1977年9月上旬对震区内的蓟县、天津、唐山、滦县、抚宁、迁西、遵化等县市进行了泥石流调查,历时20余天。调查表明,此次地震对震区泥石流有不同程度的影响。其一,在平原区使天津碱厂废碴堆发生了泥石流;其二,在北部低山丘陵区的泥石流活动有加强作用。
