通过在大地震发生后迅速钻入断裂带，可以获得有关大地震的新信息。具体来说，我们可以了解决定动态破裂的断层的摩擦水平和强度，监测断层的愈合过程，记录触发余震的应力变化，并捕获控制破裂过程的断层的重要物理和化学性质。这些科学和相关的技术问题是由国际大陆科学钻探计划（ICDP）和南加州地震中心（SCEC）主办的为期三天的快速反应断层钻探：过去，现在和未来研讨会的焦点。2008年11月，来自10个国家的44位科学家齐聚日本东京。该小组讨论了科学问题以及如何通过快速反应钻探来解决这些问题。重点介绍了以往在大地震后和断层带的钻探工作，以及实验技术和测量策略的最新进展。详细的讨论权衡了快速钻井和满足各种科学目标的能力之间的权衡。对可行的钻井地点和方案进行了评估。这是讨论关键科学问题、度量策略和建议的研讨会报告的简短摘要。这份报告可以为在未来大地震后迅速动员钻井计划提供一个起点。完整的报告可以在http://www.pmc.ucsc上看到。快速/ edu/ ~。
New information about large earthquakes can be acquired by drilling into the fault zone quickly following a large seismic event. Specifically, we can learn about the levels of friction and strength of the fault which determine the dynamic rupture, monitor the healing process of the fault, record the stress changes that trigger aftershocks and capture important physical and chemical properties of the fault that control the rupture process. These scientific and associated technical issues were the focus of a three-day workshop on Rapid Response Fault Drilling: Past, Present, and Future, sponsored by the International Continental Scientific Drilling Program (ICDP) and the Southern California Earthquake Center (SCEC). The meeting drew together forty-four scientists representing ten countries in Tokyo, Japan during November 2008. The group discussed the scientific problems and how they could be addressed through rapid response drilling. Focused talks presented previous work on drilling after large earthquakes and in fault zones in general, as well as the state of the art of experimental techniques and measurement strategies. Detailed discussion weighed the tradeoffs between rapid drilling and the ability to satisfy a diverse range of scientific objectives. Plausible drilling sites and scenarios were evaluated. This is a shortened summary of the workshop report that discusses key scientific questions, measurement strategies, and recommendations. This report can provide a starting point for quickly mobilizing a drilling program following future large earthquakes. The full report can be seen at http://www.pmc.ucsc. edu/~rapid/.
