Seismic studies on the Derbyshire dome [PDF]

open access: yes, 1983
The Derbyshire Dome is thought to have been a stable uplifted area since at least Lower Carboniferous times. This project is principally concerned with four 30km seismic refraction lines which crossed the limestone outcrop of Derbyshire and N ...

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

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 ...

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 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.

An integrated biostratigraphy and seismic stratigraphy for the late Neogene continental margin succession in northern Taranaki Basin, New Zealand [PDF]

open access: yes, 2006
Our aim has been to develop an integrated biostratigraphy and seismic stratigraphy for the Pliocene and Pleistocene formations (Ariki, Mangaa, Giant Foresets) in northern Taranaki Basin to better understand the evolution of the modern continental margin ...

An earthquake response spectrum method for linear light secondary substructures [PDF]

open access: yes, 2007
YesEarthquake response spectrum is the most popular tool in the seismic analysis and design of structures. In the case of combined primary-secondary (P-S) systems, the response of the supporting P substructure is generally evaluated without considering ...
