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.

这项合作授予了阿肯色大学，华盛顿州卡内基学会和宾夕法尼亚州立大学的运营和维护成本和维护成本的三年延续，以及对Calipso Borehole设施（加勒比海安第斯山脉熔岩岛上的Seismo-Geodetic opervatory）的一些工具升级WI。 卡里皮（Calipso）项目研究了Soufriere Hills火山（SHV）的整个岩浆系统的动力学，以增强对安第斯山脉岩浆动力学的理解。 Calipso于2002年启动，并在SHV周围的四个高敏感性井眼地震和地面变形（应变计，倾斜度计，CGPS）站进行了钻孔和安装。 最初的资金来自Ear/Continental Dynamics和仪器和设施计划，并提供了英国来源的一些贡献。 装置于2004年完成，Calipso的数据已从SHV中回收，包括2003年杂乱无章的熔岩圆顶崩溃（历史上是世界上最大的）以及2003年和2004年的爆炸。揭示了当前爆发的俯冲带的重要内部特征，安第斯山脉火山有意义，这意味着改善了对物理火山的过程以及岩浆室地球化学和岩石学过程的理解。 设施数据将补充即将到来的和耳/地球物理学以及英国资助的海上海上近海地震反射/折射实验，该实验应揭示岩浆系统中更深的（5-10公里）的特征，并大大改善了用于定位druption-druption-euption-evelocity模型相关的地震性。 来自机构的研究生和本科生将使用Sea-Calipso和Calipso设施数据进行变形和地震建模以及陆上/海上地震成像培训。 来自卡利皮设施的数据将支持减轻火山危害。 由于此支持，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。
