![]() For the regions having complex tectonic activity, b-values deviates significantly from 1.0 and in the regions characterized by stable tectonic conditions and low seismicity rates its value approaches to 1.0 over long periods of time, on the order of decades or centuries. ![]() It suggests an increasing possibility of occurrence of large magnitude earthquakes (lower b-value) and smaller magnitude earthquakes (higher b-value). The b-value measures the material heterogeneities within a fault zone and decreases with increasing stress in the brittle part of the Earth’s crust. The b-value of frequency-magnitude is a power law involving magnitude while the two-point spatial correlation dimension of earthquake’s epicenter distribution displays a power law that quantifies the proportion of randomness and clusterization. Hence, earthquakes can be described by the scaling parameter obeying power law, known as the fractal dimension. The magnitude distribution of earthquakes, the spatial distribution of epicenter/hypocenter, frequency of aftershocks etc., satisfy the power law distribution. All figures were created using the free available software Python, and Generic Mapping Tools (GMT) (Wessel et al., 2013).įunding: authors received no salary or no specific funding for this work.Ĭompeting interests: no competing interest.
