The Socompa Debris Avalanche Deposit

本项目是对智利北部有7200年历史的索孔帕火山雪崩矿床进行实地及相关研究，该矿床可以说是世界上暴露最好的大型雪崩矿床。野外工作将侧重于阐明火山的原始形状和地层，确定原始火山大厦各个组成部分雪崩的轨迹，并破译火山崩塌后的历史。数字高程模型和现有的雪崩运动动力学计算算法将被用于模拟各个组成部分的轨迹，并确定雪崩沉积物中泥石流的来源区域，遥感数据将被使用。所有这些都将被用来尽可能确定雪崩本身的动力学。

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.
