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.

这项研究提供了一个系统的评价， 分布和变形率在默拉皮火山在 未来两年，在这段时间里， 认为有可能爆发。 变形数据将 与常规遥测地震资料对比解释 印度尼西亚火山调查局获得的数据， 预计将提供有关默拉皮的基本新信息 行为 建筑物变形速度的加快 在扇区崩溃之前，或在穹顶之前的穹顶延伸 崩溃和nuees ardentes d'avalanche的产生，应该是 可检测的，并且可以使得能够测试变形和失效 Voight（1988 a）的预测方法。 因此，本研究将 将默拉皮作为一个天然实验室， 关键的火山变形过程，并测试和完善 变形监测技术
