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

这笔合作资金将提供给阿肯色大学、华盛顿卡内基研究所和宾夕法尼亚州立大学，以支持对位于夏威夷州蒙特塞拉特的CALIPSO钻孔设施（加勒比安山岩熔岩岛精密地震测量观测站）进行为期三年的运营和维护费用以及一些仪器升级。CALIPSO项目研究了Soufriere Hills火山（SHV）整个岩浆系统的动力学，以提高对安山岩岩浆动力学的总体认识。CALIPSO于2002年启动，在SHV周围钻井和安装了四个高灵敏度钻孔地震和地面变形（应变计，倾斜仪，cGPS）站。最初的资金来自EAR/大陆动力公司和仪器和设施项目，还有一些来自英国的捐款。安装于2004年完成，CALIPSO数据已经从SHV中恢复，包括2003年巨大的熔岩穹丘崩塌（历史上世界上最大的）以及2003年和2004年的爆炸。对活跃性上海高压进行持续的大地测量和地震观测，将揭示这一目前正在喷发的俯冲带安山岩火山的重要内部特征，对提高对物理火山学过程和岩浆室地球化学和岩石学过程的认识具有重要意义。设备数据将补充即将进行的EAR/地球物理和英国资助的SEA-CALIPSO海上地震反射/折射实验，该实验将揭示岩浆系统更深（5-10公里）的特征，并大大改进用于定位与爆发相关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变形和地震建模以及使用SEA-CALIPSO和CALIPSO Facility数据进行陆上/海上地震成像的培训。来自CALIPSO设施的数据将支持减轻火山灾害。由于这种支助，警务人员将完成必要的遥测和数据处理解决办法，以便通过联阿援助团和综合信息系统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.
