9418770 Dehn This award supports a 12-month Science and Technology Agency of Japan Postdoctoral Fellowship for Dr. Jonathan Dehn at the Geological Survey of Japan, Sapporo, Japan. Dr. Dehn will work with Dr. Takarada at the Hokkaido Branch on a research project entitled, "Japan STA Program: Computer Modeling of Volcanic Eruptions." The modeling of a volcanic system from eruption to deposition has been missing in volcanology. Dehn and Takarada will study the volcanogenic particles created during low energy volcanic eruptions throughout Japan. This data will be used to formulate modular quantitative models of the eruptions. Each physical component of the volcanic eruption will be modeled including vesiculation, fragmentation, ejection, subaerial transport, subaqueous transport, deposition, deformation, secondary fragmentation and mass wasting. The research team will develop a modular computer program for each component which can be added or deleted from the whole model in order to simulate nearly any volcanic condition. This model would be an important basis for comprehensive modeling of volcanic systems, and could be come a useful tool not only in the understanding of active systems but also in interpretation of ancient volcanoes and their deposits. The model would be of great use in volcanic hazard determination as well as modeling of eruptions on other planets. ***

小行星9418770 该奖项支持日本科学技术厅为Jonathan Dehn博士在日本地质调查局（札幌）提供为期12个月的博士后研究金。Dehn博士将与北海道分支的Takarada博士合作开展一个名为“日本STA计划：火山喷发的计算机建模”的研究项目。" 火山系统从喷发到沉积的模拟在火山学中一直缺失。 Dehn和Takarada将研究日本各地低能量火山爆发时产生的火山颗粒。 这些数据将用于制定喷发的模块化定量模型。 火山喷发的每个物理组成部分将被建模，包括泡状，破碎，喷射，陆上运输，水下运输，沉积，变形，二次破碎和质量浪费。 研究小组将为每个组件开发一个模块化的计算机程序，这些组件可以从整个模型中添加或删除，以模拟几乎任何火山条件。 该模型将是火山系统综合模拟的重要基础，不仅可以成为认识活动系统的有用工具，而且可以用于解释古火山及其矿床。 该模型将在火山灾害确定以及其他行星上的火山爆发建模方面有很大的用处。 ***
