Abstract The 2020 Sumbawa earthquake of moderate magnitude (M 5.3) produced very significant aftershocks. Based on the computation Utsu’s method, those aftershocks would be ended after 20th day. Those earthquakes along 20 days were relocated using double-difference method. relocation results show southwest-northeast orientation and getting deeper into northwest direction. two directions strike ...

[1] One way to probe the rheology of the lithosphere and fault zones is to analyze the temporal evolution of deformation following a large earthquake. In such a case, the lithosphere responds to a known stress change that can be assessed from earthquake slip models constrained from seismology and geodesy. Here, we model the postseismic response of a fault zone that is assumed to obey a rate-str...

Abstract Moderate-to-large-magnitude earthquakes induce considerable short-to-medium-term increases in seismic hazard, due to the subsequent occurrence of aftershocks. Most studies on aftershock models focus their performance as part Operational Earthquake Forecasting (i.e., real- or near-real-time predictions ongoing sequences). Aftershock model validation a longer timescale is scarcely dealt ...

The objective of this study was to create a representative earthquake catalog for the Eastern Sector Arctic zone Russian Federation that combines all available data from and international seismological agencies, with magnitude reduction uniform scale. article describes compilation algorithm, as well formalized procedures removing duplicates choosing optimal Due different network configurations ...

Three studies of site amplification factors, based on the recorded aftershocks, and one study based on strong motion data, are compared one with another and with the observed distribution of damage from the Northridge, CA, earthquake of 17 January 1994 …ML ˆ 6:4†: In the epicentral area, when the peak ground velocities are larger than vm < 15 cm=s; nonlinear response of soil begins to distort t...

Earthquakes and aftershock sequences follow several empirical scaling laws: One of these laws is Båth's law for the magnitude of the largest aftershock. In this work, Modified Form of Båth's Law and its application to KOERI data have been studied. Båth's law states that the differences in magnitudes between mainshocks and their largest detected aftershocks are approximately constant, independen...

The study of nonlinear site response has practical difficulties due to large ambiguities in isolating local response from other competing effects. We chose a sedimentary site LF6 in Los Angeles basin that (1) has the closest reference rock sites available, compared to other stations, allowing an accurate estimation of local amplification, and (2) illustrates clear resonance in the near surface....
