This collaborative grant to the University of Arkansas, Carnegie Institution of Washington, and Penn State supports a three year continuation of operation and maintenance costs and some instrumental upgrades of the CALIPSO Borehole Facility (Caribbean Andesitic Lava Island Precision Seismo-geodetic Observatory) on Montserrat, WI. The CALIPSO project investigates the dynamics of the entire magmatic system of Soufriere Hills Volcano (SHV) to enhance of understanding of andesitic magma dynamics in general. CALIPSO was initiated in 2002 with drilling and installation of four high-sensitivity borehole seismic and ground deformation (strainmeter, tiltmeter, cGPS) stations around the SHV. Initial funding was from EAR/Continental Dynamics and the Instrumentation and an Facilities Program with some contribution from UK sources. Installations were completed in 2004, and CALIPSO data have been recovered from SHV, including those from a prodigious lava dome collapse (historically the world's largest) in 2003, and explosions in 2003 and 2004. Continuation of geodetic and seismic observations of the active SHV should reveal important internal features of this currently erupting subduction zone andesitic volcano with implications for improved understanding of physical volcanological processes and magma chamber geochemical and petrologic processes. Facility data will complement an upcoming and EAR/Geophysics and UK funded SEA-CALIPSO offshore seismic refection/refraction experiment which should reveal deeper (5-10 km) features in the magmatic system and greatly improve the seismic-velocity models used for locating eruption-related seismicity. Graduate students and undergraduate students from the institutions will be trained in deformation and seismic modeling and onshore/offshore seismic imaging using SEA-CALIPSO and CALIPSO Facility data. Data from the CALIPSO facility will support volcanic hazard mitigation. As a result of this support the PIs will complete the telemetry and data handling solutions necessary to move the data into the public realm through the UNAVCO and IRIS archives.

这笔向阿肯色大学、华盛顿卡内基研究所和宾夕法尼亚州立大学的合作拨款支持蒙特塞拉特岛 CALIPSO 钻孔设施（加勒比安山岩熔岩岛精密地震大地观测站）的三年持续运营和维护成本以及一些仪器升级，威斯康星州。 CALIPSO 项目研究苏弗里埃尔山火山 (SHV) 整个岩浆系统的动力学，以增强对安山岩浆动力学的总体了解。 CALIPSO 于 2002 年启动，在 SHV 周围钻探和安装了四个高灵敏度钻孔地震和地面变形（应变计、倾斜计、cGPS）站。 最初的资金来自 EAR/Continental Dynamics 以及仪器和设施项目，其中一些资金来自英国来源。 安装于 2004 年完成，CALIPSO 数据已从 SHV 中恢复，包括 2003 年巨大的熔岩穹顶塌陷（历史上最大的一次）以及 2003 年和 2004 年爆炸的数据。继续对活动的 SHV 进行大地测量和地震观测揭示了这座当前喷发的俯冲带安山岩火山的重要内部特征，这对于提高对物理火山过程和岩浆的理解具有重要意义室地球化学和岩石学过程。 设施数据将补充即将进行的 EAR/地球物理学和英国资助的 SEA-CALIPSO 海上地震反射/折射实验，该实验将揭示岩浆系统中更深（5-10 公里）的特征，并大大改进用于定位喷发的地震速度模型。相关的地震活动性。 来自这些机构的研究生和本科生将接受使用 SEA-CALIPSO 和 CALIPSO 设施数据的变形和地震建模以及陆上/海上地震成像培训。 来自 CALIPSO 设施的数据将支持减轻火山灾害。 由于这种支持，PI 将完成通过 UNAVCO 和 IRIS 档案将数据转移到公共领域所需的遥测和数据处理解决方案。
