This project is for field and related studies on the 7,200-yr old Socompa volcano avalanche deposit, north Chile, which is arguably the best exposed large avalanche deposit in the world. Fieldwork will focus on elucidating the original shape and stratigraphy of the volcano, determining the trajectories within the avalanche of individual components of the original volcanic edifice and deciphering the post-collapse history of the volcano. Digital elevation models and existing computational algorithms for the kinetics of moving avalanches will be used to model the trajectories of individual components and to determine the source regions of debris streams within the avalanche deposit remote sensing data will be used. All of these will be used to determine, as far as possible, the kinetics of the avalanche itself.

本项目是对7,200岁的老年人进行实地和相关研究。 智利北部的索孔帕火山雪崩存款，可以说是 世界上最好的雪崩存款。 田野调查 将重点阐明的原始形状和地层 火山，确定雪崩的轨迹， 原始火山建筑物的各个组成部分， 解读火山崩塌后的历史 数字 海拔模型和现有的计算算法， 移动雪崩的动力学将被用来模拟 各个成分的轨迹，并确定来源 雪崩存款区内的碎屑流区域 将使用感测数据。 所有这些都将用于确定， 尽可能地研究雪崩本身的动力学
