Abstract

A large number of ground motions were obtained during recent great earthquakes such as the 2008 Wenchuan earthquake and 2011 Tohoku earthquake and some of them present double-plateau features, this paper focuses on the identification and spatial distribution of double-plateau ground motions. First, the energy-time distribution of ground motions are described by a piece-wised envelope function with double plateau, which is proposed in previous study. Then, the envelope parameters of 10 ground motions with double plateau and 10 ground motions with single plateau are used as training sample, those ground motions are classified into two groups by support vector machine, i.e., single- and double-plateau. Finally, the spatial distribution of double-plateau ground motions along the direction of ruptures are analyzed and lay the foundation for further study.
