Abstract

ABSTRACT Widespread distributed fracturing during earthquakes threatens infrastructure and lifelines. We combine high-resolution rupture maps from the five major surface-rupturing strike-slip earthquakes in southern California and northern Mexico since 1992 to incorporate the displacements produced by distributed ruptures into a probabilistic displacement hazard analysis framework. Through analysis of the spatial distribution of mapped ruptures and displacements for each of these events, we develop a magnitude-dependent expression for the probability per unit area of finding a distributed rupture that accommodates a displacement that exceeds a displacement threshold at a given distance from the principal fault. Our model is best applied to estimating expected distributed displacements for strike-slip earthquakes, similar to those analyzed, with widespread ruptures across immature fault zones.
走滑地震中分布裂缝的位移危害
地震期间广泛分布的裂缝威胁着基础设施和生命线。我们结合了自1992年以来在南加州和墨西哥北部发生的五次主要地表破裂走滑地震的高分辨率破裂图,将分布式破裂产生的位移纳入概率位移危害分析框架。通过分析这些事件中每一个断层的破裂和位移的空间分布,我们开发了一个与震级相关的表达式,用于在距离主断层给定距离处找到一个分布破裂的概率,该概率可容纳超过位移阈值的位移。我们的模型最适用于估计走滑地震的预期分布位移,类似于分析的那些,在不成熟的断裂带上有广泛的破裂。

期刊介绍: The Bulletin of the Seismological Society of America, commonly referred to as BSSA, (ISSN 0037-1106) is the premier journal of advanced research in earthquake seismology and related disciplines. It first appeared in 1911 and became a bimonthly in 1963. Each issue is composed of scientific papers on the various aspects of seismology, including investigation of specific earthquakes, theoretical and observational studies of seismic waves, inverse methods for determining the structure of the Earth or the dynamics of the earthquake source, seismometry, earthquake hazard and risk estimation, seismotectonics, and earthquake engineering. Special issues focus on important earthquakes or rapidly changing topics in seismology. BSSA is published by the Seismological Society of America.
