This research is to analyze seismic data collected during and after the eruption of Pinatubo Volcano, Luzon, Philippines. This cataclysmic 1991 eruption of Mt. Pinatubo was among the largest volcanic eruptions of the century, with profound effects on the people, landscape, and economic infrastructure of the Philippines and the climate of the world. The eruption was also one of the best recorded natural disasters in history, providing a rich and voluminous collection of seismological data that can be used both for understanding the dynamics of an explosive volcanic system and as a basis for predicting future volcanic eruptions. The primary objectives are to study the pre- and post-eruptive seismicity patterns, including the ongoing 1992-93 volcanic crisis; to study the wave-form characteristics of seismic events; to relate these studies to volcanic processes including the 1991 phreatic and paroxsysmal eruptions, the 1992 dome-forming event, secondary explosions on the pyroclastic flows, lahars, and steam jetting. The research involves close collaboration between scientists at Indiana University, the Philippine Institute of Volcanology and Seismology, the U.S. Geological Survey, and other groups involved in volcanological research at Mt. Pinatubo. This research is a component of the National Earthquake Hazard Reduction Program.

这项研究是为了分析菲律宾吕宋岛皮纳图博火山喷发期间和喷发后收集的地震数据。1991年这场灾难性的火山喷发。皮纳图博火山是本世纪最大的火山喷发之一，对菲律宾的人民、景观、经济基础设施和世界气候产生了深远的影响。这次喷发也是历史上记录最好的自然灾害之一，提供了丰富和大量的地震学数据，既可用于了解火山爆发系统的动力学，也可用作预测未来火山喷发的基础。主要目标是研究喷发前和喷发后的地震活动模式，包括正在进行的1992-93年火山危机；研究地震事件的波形特征；将这些研究与火山过程联系起来，包括1991年潜水和副对称喷发、1992年穹隆形成事件、火山碎屑流二次爆炸、火山喷发和蒸汽喷流。这项研究涉及印第安纳大学、菲律宾火山与地震研究所、美国地质调查局和其他参与山上火山研究的组织之间的密切合作。皮纳图博。这项研究是国家减少地震灾害计划的一部分。
