Evaluation of MCC seismic response according to the frequency contents through the shake table test

open access: yesNuclear Engineering and Technology, 2021
Damage to nuclear power plants causes human casualties and environmental disasters. There are electrical facilities that control safety-related devices in nuclear power plants, and seismic performance is required for them.

Low frequency earthquakes below southern Vancouver Island [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2012
The nature and distribution of low frequency earthquakes (LFEs) in subduction zones provide insight into plate boundary deformation downdip of the locked seismogenic zone. We employ network autocorrelation detection to identify LFE families beneath southern Vancouver Island and environs.

The advantage of the nonlinear mixed model and its application in typical seismically active areas in China

open access: yesDizhi lixue xuebao, 2023
As an essential parameter in earthquake prediction and risk assessment research, the b-value has received extensive attention and discussion. In this study, we chose a nonlinear mixed model to fit the earthquake magnitude-frequency distribution to the ...

A Model for Low‐Frequency Earthquake Slip [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2017
AbstractUsing high‐resolution relative low‐frequency earthquake (LFE) locations, we calculate the patch areas (Ap) of LFE families. During episodic tremor and slip (ETS) events, we define AT as the area that slips during LFEs and ST as the total amount of summed LFE slip.

The trigger mechanism of low-frequency earthquakes on Montserrat [PDF]

open access: yesJournal of Volcanology and Geothermal Research, 2006
A careful analysis of low-frequency seismic events on Soufrieere Hills volcano, Montserrat, points to a source mechanism that is non-destructive, repetitive, and has a stationary source location. By combining these seismological clues with new field evidence and numerical magma flow modelling, we propose a seismic trigger model which is based on ...

Unfolding the procedure of characterizing recorded ultra low frequency, kHZ and MHz electromagetic anomalies prior to the L'Aquila earthquake as pre-seismic ones. Part I [PDF]

open access: yes, 2009
Ultra low frequency, kHz and MHz electromagnetic anomalies were recorded prior to the L'Aquila catastrophic earthquake that occurred on April 6, 2009. The main aims of this contribution are: (i) To suggest a procedure for the designation of detected EM ...

Depth-varying rupture properties of subduction zone megathrust faults [PDF]

open access: yes, 2012
Subduction zone plate boundary megathrust faults accommodate relative plate motions with spatially varying sliding behavior. The 2004 Sumatra-Andaman (M_w 9.2), 2010 Chile (Mw 8.8), and 2011 Tohoku (M_w 9.0) great earthquakes had similar depth variations
