Volcanic hazard maps of surge boundaries and deposit thickness can be created by using a simplified eruption model based on an "energy line" concept of pyroclastic surge and flow emplacement. Computer image-processing techniques may be used to combine three-dimensional representations of the energy relations of pyroclasts moving under the influence of gravity (defined by an "energy cone") with digital topographic models of volcanoes to generate theoretical hazard maps. The deposit boundary and thickness calculated for the 18 May 1980 eruption of Mount St. Helens are qualitatively similar to those actually observed.
可以使用基于火山碎屑流和流动安置的“能量线”概念的简化喷发模型来创建涌浪边界和沉积厚度的火山灾害图。可以使用计算机图像处理技术，将在重力影响下运动的火山碎屑能量关系的三维表示（由“能量锥”定义）与火山的数字地形模型相结合，生成理论灾害图。为 1980 年 5 月 18 日圣海伦斯火山喷发计算的沉积边界和厚度与实际观察到的结果定性相似。
