“…These authors found that the values of b GR differ from the b s -index estimated using a nonextensive approach. They also found that the q-values correlated with some properties of subduction zones, such as the occurrence of ruptures, seismic/aseismic slip, coupling, and the interaction of asperities [4].…”

“…As quoted by Scherrer et al [4], the values of b GR are calculated using a software package to analyze the seismicity, denoted by ZMAP [34] 2 . These authors found that the values of b GR differ from the b s -index estimated using a nonextensive approach.…”

“…In the present paper, we investigate the the signatures of long-range persistence that are present in the earthquake magnitude times series for the Circum-Pacific subduction zones, and have been already been processed by Scheerer et al [4]. Our study applied the rescaled range (R/S) analysis as a self-affine fractal method to the magnitude time series [16].…”

“…In this paper, we show a detailed investigation of the rescaled range analysis to search for long-range correlations using the Hurst exponent in subduction zones along the Pacific Ring of Fire, the most seismically active region on Earth [4]. In particular, each zone was described using a general classification defined by an asperity model described by Scheerer et al [4]. Our main aim is to investigate two questions.…”

In the present paper, we analyze the signatures of long-range persistence in seismic sequences along Circum-Pacific subduction zones, from Chile to Kermadec, extracted from the National Earthquake Information Center (NEIC) catalog. This region, known as the Pacific Ring of Fire, is the world's most active fault line, containing about 90% of the world's earthquakes. We used the classical rescaled range (R/S) analysis to estimate the long-term persistence signals derived from a scaling parameter called the Hurst exponent, H. We measured the referred exponent and obtained values of H > 0.5, indicating that a long-term memory effect exists. We found a possible fractal relationship between H and the b s (q)-index, which emerges from the non-extensive Gutenberg-Richter law as a function of the asperity. Therefore, H can be associated with a mechanism that controls the level of seismic activity. Finally, we concluded 1 arXiv:1912.02092v1 [physics.geo-ph] 3 Dec 2019Running title • November 2012 • Vol. XXI, No. 1 that the dynamics associated with fragment-asperity interactions can be classified as a self-affine fractal phenomenon.
