Collaborative Research: Patterns of Serial Fault Rupture in Taiwan

提案摘要EAR0107114和EAR0106827（PH #39x）标题：合作研究：台湾连续断层破裂的模式。Rubin，中央华盛顿大学（EAR 0107114）和Kerry Sieh，加州理工学院（EAR 0106827）拟议工作摘要了解断层的连续破裂是地震科学的基本目标之一。 简单地说，问题是：断裂如何在断层和断层系统上重复？ 虽然这个问题是我们科学的实践和学术方面的核心，但它在很大程度上仍然没有答案，主要是因为数据很难获得。 三个最重要的问题是：1）断层破裂之间的间隔有多规律？2)断层滑动的模式有多可重复？3)地质构造如何影响断层破裂？ 这些都是我们建议在台湾的古地震和新构造研究中开始着手解决的问题。第一年，我们的勘察工作将集中在沿着1999年车笼埔断层破裂的古地震调查和准备全台湾的新构造和震源图。 我们希望沿着车龙埔的一处地点的史前地震活动记录，能开始检验几个合理的假设，从无模式或随机重复到高度聚集的行为。 如果成功的话，我们的工作将证明继续工作的理解地震断层和断层相互作用的理论模型提供限制。 我们的新构造地震震源图将为未来研究那里的断层行为提供背景。

Abstract for proposals EAR0107114 and EAR0106827 (PH #39x)Title: Collaborative Research: Patterns of Serial Fault Rupture in TaiwanPI's: Charles M. Rubin, Central Washington Univ (EAR0107114) and Kerry Sieh, CalTech (EAR0106827)ABSTRACT OF PROPOSED WORKUnderstanding the sequential rupture of faults is one of the fundamental goals in earthquake science. Simply stated, the question is: How do ruptures repeat on a fault and on systems of faults? Although this question is at the heart of both practical and academic aspects of our science, it remains largely unanswered, mostly because data are difficult to obtain. Three of the most important issues are 1) How regular are intervals between fault ruptures? 2) How repeatable is the pattern of slip on a fault? 3) How does geologic structure influence fault rupture? These are questions we propose to begin to tackle through paleoseismic and neotectonic studies in Taiwan. During our first year, our reconnaissance work would focus on paleoseismic investigations along the 1999 rupture of the Chelungpu fault and on preparation of a neotectonic and earthquake source map of all of Taiwan. The record of prehistoric seismicity along the Chelungpu at one site we hope to begin to test a few plausible hypotheses, ranging from unpatterned or random recurrence to highly clustered behavior. If successful, our work will justify continued work on understanding of earthquake faults and provide constraints on theoretical models of fault interaction. Our neotectonic earthquake source map will provide the context for future studies of fault behavior there.
