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 Fosterthis Earth Sciences仪器仪器和设施计划赠款支持对全球定位系统（GPS）设备的获取和纪念碑，以升级和增强夏威夷大岛上现有的GPS网络。 具体来说，Kilauea上的六个16岁的GPS网站将被新的接收器和天线所取代，夏威夷西海岸的五个临时站点将升级，使其成为不断运行的遥测网络的一部分。 启用和确保的GPS观察将支持对与Kilauea和Mauna LOA内的主动瓦肯岩相关的地下岩浆活动的研究，例如，基拉韦阿南侧的慢速滑倒）以及通过GPS促进的测量方法通过可促进的水vapor in The vaper in The Tropopsophere in vps of vps的测量。 更好地理解缓慢的滑移事件及其与地震周期的关系对于理解导致主要，可能是海啸，地震的条件至关重要。 Kilauea的南侧是水下作为主要的海底滑坡，如果灾难性地崩溃，将导致东部太平洋海啸导致东部的海啸。对此功能及其机械和动力学行为的更清晰了解及其与岩浆过程的联系将大大有助于危害评估。 此升级促进的当地参考框架的改进将使民用，研究和工业社区受益。 ***
