Collaborative Research: Patterns of Serial Fault Rupture in Taiwan

题目：合作研究：台湾连续断层破裂模式pi’s: Charles M. Rubin，中央华盛顿大学（EAR0107114）和Kerry Sieh，加州理工学院（EAR0106827）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：断裂是如何在断层和断层系统上重复发生的？尽管这个问题是我们科学实践和学术方面的核心，但它在很大程度上仍未得到解答，主要是因为数据难以获得。最重要的三个问题是：1)断层破裂的间隔有多规律？2)断层滑动模式的可重复性如何？3)地质构造如何影响断层破裂？这些都是我们建议通过台湾的古地震和新构造研究来着手解决的问题。在我们的第一年，我们的侦察工作将集中在1999年车隆堡断裂的古地震调查，以及准备全台湾的新构造和震源图。我们希望通过对车龙坡沿线一个地点的史前地震活动记录，开始测试一些看似合理的假设，从无模式或随机复发到高度聚集的行为。如果成功，我们的工作将证明继续了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。我们的新构造震源图将为那里的断层行为的未来研究提供背景。

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.
