Nonextensive analysis of seismic sequences
Physica A: Statistical Mechanics and its Applications, 2010By using the Tsallis-based nonextensive statistics, the analysis of the magnitude distribution of several seismic catalogues in Italy was performed. The analysis shows similar values for the q-value, in good agreement with those obtained for other seismotectonic settings [e.g. Silva et al. (2006) [2] and Vilar et al. (2007) [3]].

Seismic Facies Analysis Based on Deep Learning
IEEE Geoscience and Remote Sensing Letters, 2020Seismic facies analysis is to study the sedimentary environment of stratigraphic sequence and provides an important basis for reservoir prediction. Most of the existing analysis methods have low efficiency and heavily rely on manual experience, and ...

Publisher Summary This chapter begins by providing a general understanding on seismology. Due to the movement of the pile cap, piles are subjected to additional shear forces and bending moments. Earthquakes occur as a result of disturbances occurring inside the earth's crust. Earthquakes produce three main types of waves—primary waves, secondary waves,

Common-azimuth seismic data fault analysis using residual UNet
, 2020Seismic fault interpretation is one of the key steps for seismic structure interpretation, which is a time-consuming task and strongly depends on the experience of the interpreter.

Seismic Analysis of Cooling Towers
Engineering Structures, 1984Abstract Hyperbolic natural-draught cooling towers to be erected in seismically active zones are routinely analysed for earthquake excitation. The axisymmetric shell is discretized with higher order finite element frusta, with an isoparametric expansion in the meridional direction and a Fourier expansion in the circumferential direction.

On Multisite Probabilistic Seismic Hazard Analysis
Bulletin of the Seismological Society of America, 2016Abstract Seismic hazard assessment, in its classical format, models the stochastic process of occurrence of earthquakes causing the exceedance of ground‐motion intensity measure (IM) thresholds at a specific site. This is because civil structures typically require probabilistic seismic hazard analysis (PSHA) for one location.

Seismic Fragility Analysis of Structural Systems
Journal of Engineering Mechanics, 2006A method is presented for the evaluation of the seismic fragility function of realistic structural systems. The method is based on a preliminary, limited, simulation involving nonlinear dynamic analyses performed to establish the probabilistic characterization of the demands on the structure, followed by the solution of a general system reliability ...

Towards a complete framework for seismic analysis in Abaqus
, 2014The nuclear industry currently employs a limited and ageing range of computational tools for seismic and soil–structure interaction analysis. This paper presents a set of new tools that have been developed for two and three-dimensional seismic analysis ...

Online Analysis of Seismic Signals
2004Seismic signals can be modeled as non-stationary time series. Methods for analyzing non-stationary time series that have been recently developed are proposed in Adak [1], West, et al. [25] and Ombao, et al. [12]. These methods require that the entire series be observed completely prior to analyses.

Comparative analysis of the seismic risk in sites of different seismicity
Earthquake Engineering & Structural Dynamics, 1977AbstractFour sites (a, b, c, d) are considered of differing seismicity. The calculations, for two different buildings on each site, consisted of: The total monetary cost as a function of the design seismic coefficient c. The marginal cost of a saved life, ΔD/ΔL, also depending on c.
