Albania is located in the Alpine fold belt extending to the central part of the Dinarides–Hellenides arc in a zone characterized by intense tectonic-seismic activity that has a considerable influence in shaping the geo-environment of the area. Historically, strong earthquakes occurred in this region and triggered lots of mass movements causing considerable damages such as life loss, destruction of properties and disruption of the geo-environment. This paper introduces several earthquake-triggered mass movement events in Albania that occurred during 1850–2019. It was achieved through collection and analysis of data from historical studies and authors’ field investigations. The results show that soil type, slope inclination and seismic activity have a direct influence in the occurrence of these movements consistent with similar parameters occurred worldwide. Earthquake’s magnitude and degree of mass movement is well correlated. Mass movements such as lateral earth spread, rock fall, debris slides, sand boils, sand fluidization, cracks and settlement were triggered by earthquakes with a magnitude of 6.0 or higher. On the other hand, lateral rock spread needs a higher seismic magnitude to occur.

阿尔巴尼亚地震引发的群众运动

阿尔巴尼亚位于阿尔卑斯褶皱带,延伸至 Dinarides-Hellenides 弧的中部,该区域以强烈的构造地震活动为特征,对塑造该地区的地质环境有相当大的影响。历史上,该地区发生过强烈地震并引发了大量的群众运动,造成了生命损失、财产破坏和地质环境破坏等相当大的破坏。本文介绍了 1850 年至 2019 年发生在阿尔巴尼亚的几起地震引发的群众运动事件。它是通过收集和分析来自历史研究和作者实地调查的数据来实现的。结果表明,土壤类型、斜坡倾角和地震活动对这些运动的发生有直接影响,这些运动与世界范围内发生的类似参数一致。地震的震级和群众运动的程度是密切相关的。6.0 级或更高的地震引发了诸如横向地球扩展、岩石坠落、泥石流、砂沸、砂流化、裂缝和沉降等质量运动。另一方面,横向岩石扩展需要更高的地震震级才能发生。
