Collaborative Research: Facility Support for the CALIPSO Borehole Observatory, Soufriere Hills Volcano, Montserrat

这笔给阿肯色大学、华盛顿卡内基研究所和宾夕法尼亚州立大学的合作赠款用于支付三年的运营和维护费用，以及对位于威斯康星州蒙特塞拉特的CALIPSO钻孔设施(加勒比海安第奇熔岩岛精密地震大地测量观测站)进行一些仪器升级。CALIPSO项目研究苏弗里埃尔山火山(SHV)整个岩浆系统的动力学，以加强对安山岩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的钻孔地震和地面形变(应变仪、倾斜仪、CGPS)站。最初的资金来自EAR/大陆动力和仪器设备计划，英国的一些来源也提供了一些捐款。安装工作于2004年完成，从SHV恢复了CALIPSO数据，包括2003年巨大的熔岩穹顶坍塌(历史上是世界上最大的)以及2003年和2004年的爆炸。继续对活动的SHV进行大地测量和地震观测，应该会揭示这一目前正在喷发的俯冲带和玄武岩火山的重要内部特征，这将有助于更好地理解火山物理过程和岩浆房的地球化学和岩石学过程。设施数据将补充即将到来的和EAR/地球物理和英国资助的SEA-CALIPSO近海地震反射/折射实验，该实验将揭示岩浆系统更深(5-10公里)的特征，并极大地改进用于定位与喷发有关的地震活动的地震速度模型。这些机构的研究生和本科生将接受有关形变和地震建模以及使用SEA-CALIPSO和CALIPSO设施数据的陆上/近海地震成像方面的培训。CALIPSO设施的数据将支持减轻火山灾害。由于这一支持，私人投资机构将完成必要的遥测和数据处理解决方案，以便通过联安援助团和IRIS档案将数据转移到公共领域。

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.
