地震活动率的空间标度

On the Spatial Scaling of Seismicity Rate

G. Molchan, T. Kronrod

摘要:

空间-时间-震级域中地震活动性的标度分析通常从关系式N(m,L)=a(L)*10**(-bm)*L**c开始,即在大小为L的区域中震级M>m的震波迹象的发生率。有一些证据支持地震活动中存在多重分形。在这种情况下,标度指数c的最佳选择不是唯一的。它示出了不同的c如何与应用于N(m,L)的不同类型的空间平均相关,以及对于小L,a(L)的分布最佳地一致的c是什么。理论分析使用加州的数据进行了测试。

英文摘要:

Scaling analysis of seismicity in the space-time-magnitude domain very often starts from the relation N(m,L)=a(L)*10**(-bm)*L**c for the rate of seismic events of magnitude M>m in an area of size L. There is some evidence in favor of multifractality being present in seismicity. In this case the optimal choice of the scale exponent c is not unique. It is shown how different c's are related to different types of spatial averaging applied to N(m,L) and what are the c's for which the distributions of a(L) best agree for small L. Theoretical analysis is tested using California data.
