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.

提议摘要EAR0107114和EAR0106827（ph＃39X）标题：协作研究：台湾序列断裂的模式：Charles M. Rubin，Charles M. Rubin，Central Washington Univ（EAR0107114）和Kerry Sieh和Kerry Sieh，Caltech，Caltech（EAR01010106827）的摘要效果，是临时的临时目标。地震科学。 简而言之，问题是：如何在故障和故障系统上重复破裂？ 尽管这个问题是我们科学的实践和学术方面的核心，但它基本上仍未得到答复，主要是因为很难获得数据。 最重要的三个问题是1）断裂破裂之间的间隔程度如何？ 2）在故障上滑动的模式有多可重复？ 3）地质结构如何影响断层破裂？ 这些是我们提出的问题，以开始通过台湾的古糖酶和新遗传学研究来解决。在我们的第一年，我们的侦察工作将集中于1999年Chelungpu断层破裂的古呼吸调查，并准备整个台湾全部的新原子和地震来源图。 我们希望在一个地点沿Chelungpu的史前地震活动记录，我们希望开始检验一些合理的假设，从不公平或随机复发到高度聚类的行为。 如果成功的话，我们的工作将证明对理解地震断层的持续工作是合理的，并对故障相互作用的理论模型提供了限制。 我们的新原校地震源图将为未来对故障行为的研究提供背景。
