9417605 Sheridan The objective of this proposal is to obtain a better understanding of the physical and geochemical processes related to the giant 1964 eruption of Shiveluch Volcano, Kamchatka. The eruptive event and products of Shiveluch, the focus of this research, will be compaped with published information and reconnaissance field work on the other major edifice destroying eruptions Kusdach (1907), Bezymianny (1956), and Mount St. Helens (1980) . The goal will be to understand the similarities and differences of these four major eruptions. Field and laboratory studies will ascertain the nature of processes leading to the explosive rupture of the eruptive system and the mechanism responsible for the lateral transport of the materials. Integrated study of the eruptive history of the entire volcano and the petrologic and geochemical character of the juvenile products will provide data to determine possible relationships among: characteristics of eruptive events, evolution of the melts, formation of volcanic debris avalanches, and occurrence of lateral blast eruptions. This research would improve our understanding of a very important class of phenomena that has a significant impact on volcanic risk assessment and mitigation. Results form this study also could prove useful for long-term prediction of eruptive behavior at other dangerous volcanoes.

9417605 Sheridan这项提议的目的是更好地了解与1964年堪察加Shiveluch火山巨大喷发有关的物理和地球化学过程。这项研究的重点Shiveluch的喷发事件和产品将与已公布的信息和关于摧毁库斯达赫(1907)、贝兹明尼(1956)和圣海伦斯火山(1980)的其他主要建筑物的实地勘察工作进行比较。目标将是了解这四个主要喷发的异同。实地和实验室研究将确定导致喷发系统爆炸破裂的过程的性质，以及负责材料横向运输的机制。对整个火山的喷发史和幼年产物的岩石学和地球化学性质的综合研究将提供数据，以确定喷发事件的特征、熔体的演化、火山碎屑雪崩的形成和侧向爆炸喷发的发生之间的可能关系。这项研究将提高我们对一类非常重要的现象的理解，这类现象对火山风险评估和缓解具有重大影响。这项研究的结果也可能被证明对其他危险火山的喷发行为的长期预测有用。
