Dome Deformation and Structural Collapse at Merapi Volcano, Java

这项研究为未来两年默拉皮火山的分布和变形速率提供了系统的评估——在这段时间里，人们认为可能会发生一次重大的爆炸性喷发。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相关联进行解释，并有望提供有关默拉皮火山活动的基本新信息。应该可以探测到在扇形崩塌之前的大厦变形速率的加速，或者在穹顶崩塌之前的穹顶扩展速率的加速，并产生新的雪崩强度，从而可以对Voight （1988a）的变形和破坏预测方法进行测试。因此，这项研究将使默拉皮火山作为一个自然实验室，既可以了解关键的火山变形过程，又可以测试和改进变形监测技术。

This research provides for a systematic evaluation of the distribution and rates of deformation at Merapi volcano over the next two years -- a period during which a significant explosive eruption is considered likely. Deformation data will be interpreted in correlation with conventional telemetered seismic data obtained by the Volcanological Survey of Indonesia, and is expected to provide fundamental new information on Merapi behavior. An acceleration in the rate of edifice deformation preceding sector collapse, or of dome extension preceding dome collapse and generation of nuees ardentes d'avalanche, should be detectable, and may enable tests of the deformation and failure prediction method of Voight (1988a). Thus, this research will enable use of Merapi as a natural laboratory to both understand crucial volcano deformational processes, and to test and refine deformation monitoring techniques.
