Seismic Hazard Analysis

2021
This section explains the fundamentals of seismic hazard analysis as part of earthquake engineering. According to Elnashai and Di Sarno (Fundamentals of earthquake engineering: from source to fragility. Wiley, London, 2015), Earthquake Engineering is a branch of engineering concerned with the estimation of earthquake consequences and the mitigation of ...

Hydraulic Fracturing Induced Seismicity in the Southern Sichuan Basin Due to Fluid Diffusion Inferred From Seismic and Injection Data Analysis

Geophysical Research Letters, 2020
In the southern Sichuan Basin, China, the recent increase in the seismic activity has been suspected to be related to hydraulic fracturing stimulation for producing the shale gas.

Seismic Hazard Analysis

2018
This chapter highlights the significance of Ground Motion Prediction Equations to estimate the seismic hazard at a region based on earthquake magnitude and source to site distance. A glimpse of both deterministic and probabilistic approaches for hazard assessment is presented along with a discussion on the logic tree framework.

Seismic graph analysis to aid seismic interpretation

Interpretation, 2019
During the seismic interpretation process, geoscientists rely on their experience and visual analysis to assess the similarity between seismic sections. However, evaluating all of the seismic sections in a 3D survey can be a time-consuming task. When interpreters are working on a data set, a common procedure is to divide the cube in increasingly finer ...

Common-azimuth seismic data fault analysis using residual UNet

, 2020
Seismic 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 Facies Analysis Based on Deep Learning

IEEE Geoscience and Remote Sensing Letters, 2020
Seismic 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 ...

Seismic Analysis of Cooling Towers

Engineering Structures, 1984
Abstract 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.

Seismic Fragility Analysis of Base-Isolated Building Frames Excited by Near- and Far-Field Earthquakes

Journal of performance of constructed facilities, 2019
The present study aims at the probabilistic seismic risk assessment of a base-isolated building frame under near- and far-field earthquakes by conducting a fragility analysis.

Probabilistic seismic hazard analysis for seismic sequences

2013
Earthquakes are typically clustered both in space and time. Seismic h azard , expressed in terms of rate of exceedance of a ground motion intensity measure , classically refers to ma i nshock s, which means that such a rate is computed filtering the rate o f occurrence of events of largest magnitude within each cluster of earthquakes.

Probabilistic Seismic Hazard Analysis for Induced Seismicity

2020
In recent times, there has been increased seismicity in geologically stable basins in North America, thought to be associated with hydraulic fracturing and/or waste water disposal activities. Induced events could generate a seismic hazard higher than natural seismicity, particularly in areas with small-to-moderate natural background seismicity, leading
