Quantitative assessment of the spatio-temporal correlations of seismic events induced by longwall coal mining

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2022
Rock failure process as a natural response to mining activities is associated with seismic events, which can pose a potential hazard to mine operators, equipment and infrastructures. Mining-induced seismicity has been found to be internally correlated in

Unsupervised pre-stack seismic facies analysis constrained by spatial continuity

open access: yesArtificial Intelligence in Geosciences, 2023
Seismic facies analysis plays important roles in geological research, especially in sedimentary environment identification. Traditional method is mainly based on seismic waveform or attributes of a single seismic gather to classify the seismic facies ...

A new methodology for modeling explicit seismic common cause failures for seismic multi-unit probabilistic safety assessment

open access: yesNuclear Engineering and Technology, 2020
In a seismic PSA, dependency among seismic failures of components has not been explicitly modeled in the fault tree or event tree. This dependency is separately identified and assigned with numbers that range from zero to unity that reflect the level of ...

A Seismic Demand Model for Bridges Based on IM and EDP Parameter Matching and Bidirectional Optimization

open access: yesShock and Vibration, 2021
The accuracy of seismic demand models in seismic vulnerability analysis of structures or components mainly depends on the seismic intensity measures (IMs) and engineering demand parameters (EDPs).

Correlation analysis between ground motion parameters and seismic damage of buildings for near-field ground motions

open access: yesNatural Hazards Research, 2022
Pulse-like ground motions constitute a significant challenge to the performance of buildings, as they are characterized by long intense velocity, displacement, or acceleration pulses.

Interferometric surface-wave isolation and removal [PDF]

open access: yes, 2007
The removal of surface waves (ground roll) from land seismic data is critical in seismic processing because these waves tend to mask informative body-wave arrivals.

Comparative analysis of observation data between DSQ water-tube tiltmeter and VS vertical pendulum tiltmeter at Ganzhou seismic center station in Jiangxi

open access: yes地震科学进展, 2023
Using the co-seismic response data from the DSQ water-tube tiltmeter and the VS vertical pendulum tiltmeter at the Ganzhou seismic center station in Jiangxi, we analyze the maximum response amplitude, the delay time and the continuous response time of ...
