We presented time series analysis of multifractal properties of M≥7.0 earthquakes in Himalaya and vicinity during the period 1895-1995. The multifractal analysis of complex phenomena involves the estimation and interpretation of Dq-q relation. Our investigations show that: (1) the distribution of earthquakes of M≥7.0 on the time axis has a multifractal set, (2) well distributed, steep type decreasing function of Dq with increasing q, indicates high rates of accumulation and release; therefore, leading to adjustment of a large scale stress field in the area, and (3) value of D2 = 0.95 > D2 > D∞ = 0.80.

Abstract


We presented time series analysis of multifractal properties of M≥7.0 earthquakes in Himalaya and vicinity during the period 1895-1995. The multifractal analysis of complex phenomena involves the estimation and interpretation of Dq-q relation. Our investigations show that: (1) the distribution of earthquakes of M≥7.0 on the time axis has a multifractal set, (2) well distributed, steep type decreasing function of Dq with increasing q, indicates high rates of accumulation and release; therefore, leading to adjustment of a large scale stress field in the area, and (3) value of D2 = 0.95 > D2 > D∞ = 0.80.
