摘要:
2013-04-20四川芦山Ms7.0级强烈地震造成了极大的破坏,主震后发生了密集的余震,对其初期余震时间变化规律的认识有助于科学指导灾后重建和防灾减灾工作。根据国家地震科学数据共享中心的中国地震台网2013-04-20—05-06期间的余震时间序列数据,运用分形计盒维数的方法,研究不同震级阈值下余震序列的分形演化特征。结果表明,不同震级的芦山余震序列均表现出标度不变性和自相似特征,意味着对某震级阈值以上的余震来说,较小时间尺度内的数量与较高时间尺度内的余震数量具有相同的幂律分布规律,可以直接根据分形盒维数推算出未来某一时间尺度内高于某一震级阈值的余震的数量,这在高震级余震预测预报中有着重要的...
