Collaborative Research: Patterns of Serial Fault Rupture in Taiwan

建议摘要EAR0107114和EAR0106827(PH#39x)标题：合作研究：台湾的系列断层破裂模式：中央华盛顿大学的Charles M.Rubin(EAR0107114)和加州理工大学的Kerry Sieh(EAR0106827)建议的WORK摘要了解断层的顺序破裂是地震科学的基本目标之一。简单地说，问题是：如何在一个断层和断层系统上重复破裂？尽管这个问题是我们科学的实践和学术方面的核心问题，但它在很大程度上仍然没有得到回答，主要是因为数据很难获得。其中最重要的三个问题是：1)断层破裂之间的间隔有多大规律？2)断层上滑动模式的重复性有多大？3)地质构造如何影响断层破裂？这些都是我们建议在台湾开始通过古地震和新构造研究来解决的问题。在我们的第一年，我们的勘察工作将集中在1999年车龙铺断裂沿线的古地震调查和编制全台新构造和地震震源图。我们希望在一个地点开始测试几个合理的假设，从无模式或随机重复到高度聚集的行为，沿着车龙铺的史前地震活动的记录。如果成功，我们的工作将证明继续理解地震断层的工作是合理的，并为断层相互作用的理论模型提供约束。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.
