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.

自1984年12月以来，阿拉斯加的Redoubt火山一直处于喷发状态。这个探索性研究项目是为了部署一个便携式天文台，以获得急需的地面真相信息。目前，在Redoubt火山有一个独特的研究机会，可以了解火山喷发过程、冰川-火山相互作用以及对安山岩活火山地震活动的解释。大部分需要的设备（地震仪、电视摄像机和收音机）已经由AVO和W.M. Keck基金会的资金购买。额外设备、出版费用等可另行拨款。这座建筑将建在火山以北14公里处4000英尺高的冰脊上。它有一个双层屋顶，以防止可能发生的浮石炸弹，研究人员将在冰上挖一个防空洞，以防止不太可能发生的强烈爆炸。目前的地震活动性是如此之高，以至于即使在很短的时间内，例如10天的观测窗口，人们也可以了解到引起各种各样的地面振动的物理过程。预算用于1个月的私人调查时间，直升机部署小屋以及基本的视频和摄影设备。实验的额外费用将由AVO支付，作为NSF基金的匹配资金。
