Close Range Observation of Eruptive Processes at Redoubt Volcano, Alaska

阿拉斯加的堡垒火山自 1984 年 12 月以来一直处于喷发状态。该探索性研究项目旨在部署便携式观测站，以获取急需的地面实况信息。 目前，堡垒火山存在一个独特的研究机会，可以深入了解安山活火山的喷发过程、冰川-火山相互作用以及地震活动的解释。 AVO 和 W.M. 已购买了大部分所需设备（地震仪、电视摄像机和收音机）。凯克基金会资金。 额外的设备、出版费用等可单独提供资金。该建筑将位于火山以北 14 公里处 4000 英尺高的山脊上的冰上。 它有一个双层屋顶，可以防止可能的浮石炸弹，研究人员会在冰上挖一个防空洞，以应对不太可能发生的强烈爆炸。 目前地震活动如此之高，即使在很短的时间内，例如 10 天的观测窗口，人们也可以了解很多有关导致各种地面振动的物理过程的信息。 预算为 P.I. 1 个月的预算。时间，直升机部署小屋和基本的视频和摄影设备。 该实验的额外费用将由 AVO 承担，作为 NSF 拨款的配套资金。

Redoubt Volcano, Alaska has been in a state of eruption since December 1984. This exploratory research project is for deployment of a portable observatory to obtain badly needed ground-truth information. A unique research opportunity exists at present at Redoubt Volcano to learn much about eruptive processes, glacier-volcano interaction and interpretation of seismicity at an active andesitic volcano. Most of the needed equipment (Seismographs, TV cameras and radios) have already been purchased by AVO and W.M. Keck Foundation funds. Separate funding is available for additional equipment, publication charges etc. The building would be located on ice on a 4000' high ridge 14 km north of the volcano. It has a double roof for protection against possible pumice bombs and researches would dig a bomb shelter in the ice for the unlikely event of a very strong explosion. The seismicity is so high at present that even in a short, e.g., 10 day, observation window, one could learn a lot about the physical processes that cause the great variety of ground vibrations. The budget is for 1 month of P.I. time, helicopter deployment of the hut and basic video and photographic equipment. Additional costs for the experiment will be covered by AVO as matching funds for this NSF Grant.
