火山土在世界各地广泛存在，它们是几个城市的基础，因此了解它们的地质技术特性非常重要，特别是因为导致它们沉积的相同地质过程也会产生地震。火山土壤中的滑坡往往是灾难性的，往往是由地震和强降雨引发的。尽管这些土壤分布广泛，而且它们在地震和强降水期间变得高度不稳定的趋势带来的危害也很大，但发表的关于它们的岩土特性的研究相对较少，更不用说试图确定它们的共同特性并为它们的行为制定一个通用模型了。在介绍中美洲火山土样品测试方案和探索性斜坡稳定性分析的一些结果之前，简要审查了世界上几个地点的火山土研究。
Volcanic soils are widely encountered around the world and they underlay several cities, making an understanding of their geotechnical properties of great importance, particularly since the same geological processes responsible for their deposition also generate earthquakes. Landslides in volcanic soils, often of catastrophic proportions, are frequently triggered both by seismic ground shaking and by heavy rainfall. Despite the wide occurrence of these soils and the hazards associated with their tendency to become highly unstable during earthquakes and heavy precipitation, there are relatively few published studies on their geotechnical characterisation, much less attempts to identify common properties and formulate a generic model for their behaviour. Studies of volcanic soils in a few locations around the world are briefly reviewed, prior to the presentation of some results of testing programmes on volcanic soil samples from Central America and exploratory slope stability analyses.
