Deformation and Real-Time Seismic Amplitude Monitoring at Merapi Volcanic, Java

该合同提供了购买设备所需资金的三分之一，用于监测印度尼西亚默拉皮火山的地震、变形和爆炸活动。此次收购的额外资金已由宾夕法尼亚州立大学承诺。利用这种设备进行监测，将有可能系统地评估默拉皮火山在未来几年的变形情况，在这段时间内，人们认为可能会发生一次重大的爆炸性喷发。所要求的设备包括电子倾斜仪和随附的遥测系统，以监测穹顶的活动，以及一个“全站”测量系统，以实现对默拉皮大厦变形的专用全天候监测。变形数据将与印度尼西亚火山调查局获得的常规遥测地震数据以及由首席研究员安装的实时地震振幅监测系统一起进行解释。用这种仪器进行的研究将使默拉皮火山成为一个自然实验室，以了解关键的火山变形过程，并在火山喷发之前和期间测试和完善变形模型。

This award provides for one-third of the funding needed for the acquisition of equipment to monitor seismic, deformational, and explosive activity at Merapi volcano in Indonesia. The additional funding for this acquisition has been committed by the Pennsylvania State University. Monitoring with this equipment will make it possible to systematically evaluate the deformation at Merapi volcano over the next few years, a period within which a significant explosive eruption is considered likely. The equipment requested includes electronic tiltmeters and accompanying telemetry systems to monitor dome activity and a "total station" surveying system to enable dedicated, full-time monitoring of the Merapi edifice deformation. Deformational data will be interpreted in conjunction with conventional telemetered seismic data obtained by the Volcanological Survey of Indonesia as well as a real-time seismic amplitude monitoring system to be installed by the Principal Investigator. The research to be carried out with this instrumentation will enable Merapi volcano to be used as a natural laboratory to understand crucial volcano deformational processes, and to test and refine deformation models before and during volcanic eruption.
