1262093FosterThis Division of Earth Sciences Instrumentation and Facilities Program grant supports acquisition and monumentation of Global Positioning System (GPS) equipment to upgrade and augment an existing GPS network on Hawaii's Big Island. Specifically, six 16-year old GPS sites on Kilauea will be replaced with new receivers and antennas and five temporary sites on Hawaii's west coast will be upgraded to make them part of the continuously operating, telemetered network. The GPS observations enabled and secured will support research on the subsurface magmatic activity associated with active vulcanism within Kilauea and Mauna Loa and related tectonics (e.g., slow slip on the south flank of Kilauea) as well as studies of regional meteorological dynamics through GPS facilitated measurements of precipitable water vapor in the troposphere. A better understanding of slow slip events and their relationship to the earthquake cycle is of fundamental importance in understanding the conditions leading to major, possibly tsunamigenic, earthquakes. Kilauea?s south flank extends underwater as a major submarine landslide that would cause an eastern Pacific-wide tsunami should it collapse catastrophically. Clearer understanding of this feature and its mechanical and dynamical behavior, and its connection to magmatic processes, will significantly assist hazard assessments. The improved local reference frame facilitated by this upgrade would benefit the civil, research and industrial communities. ***

1262093福斯特地球科学仪器和设施计划拨款支持全球定位系统（GPS）设备的收购和纪念，以升级和扩大现有的GPS网络在夏威夷的大岛。 具体而言，基拉韦厄上六个已有16年历史的GPS站点将被新的接收器和天线取代，夏威夷西海岸的五个临时站点将被升级，使其成为连续运行的遥测网络的一部分。 启用和保护的GPS观测将支持对与基拉韦厄和莫纳罗亚火山内活跃火山活动相关的地下岩浆活动以及相关构造（例如，基拉韦厄南翼的缓慢滑动）以及通过全球定位系统对区域气象动力学进行的研究促进了对流层可降水量的测量。 更好地了解慢滑事件及其与地震周期的关系，对于了解导致大地震（可能是海啸）的条件至关重要。基拉韦厄？它的南侧延伸到水下，是一个主要的海底滑坡，如果它灾难性地倒塌，将引起东太平洋范围的海啸。更清楚地了解这一特征及其机械和动力学行为，以及它与岩浆过程的联系，将大大有助于危险评估。 这一升级有助于改进地方参考框架，将使民间、研究和工业界受益。***
