Multi-component seismic surveying for near surface investigations: examples from central Wyoming and southern England
Within the crust, the weathered layer has been shown to contain some of the greatest values of shear wave velocity anisotropy. There are two main causes of this shear wave velocity anisotropy. In all rock types, anisotropy results from structural weaknesses commonly manifest as aligned open fractures. In sedimentary rocks, additional anisotropy can result from mineral or grain particle alignmen...
متن کاملApplication of Near Surface Mounted (NSM) technique for Seismic Retrofitting of Heritage Buildings
The high vulnerability of the cultural buildings due to seismic actions urged researchers to retrofit them using reversible and compatible techniques. The application of fiber reinforced polymer (FRP) for enhancing the structural behavior of masonry buildings, under seismic actions, has been studied by many researchers. The near-surface mounting (NSM) technique is a relatively new retrofitting ...
متن کاملEstimating Seismic Attenuation (Q) by an Analytical Signal Method
The analytical signal method for seismic attenuation (Q) estimation is reviewed and investigated using a 1D surface data model and field VSP data. The error in Q-factor recovery from modelled data using the analytical signal method is better than 7 percent over a range of Q-factors from 25 to 100. The method is applied to the enhanced downgoing P-wave of an offset VSP-survey from Ross Lake, Sas...
متن کاملGRM: Generalized Regression Model for Clustering Linear Sequences
Linear relation is valuable in rule discovery of stocks, such as ”if stock X goes up 1, stock Y will go down 3”, etc. The traditional linear regression models the linear relation of two sequences perfectly. However, if user asks ”please cluster the stocks in the NASDAQ market into groups where sequences have strong linear relationship with each other”, it is prohibitively expensive to compare s...
متن کاملEstimation of Absorbing Boundary Parameters for near Surface Seismic Modeling
Artificial boundaries are necessary in seismic numerical modeling to constrain the computational limits. Special treatment is necessary to reduce spurious reflections from these artificial boundaries. For near-surface seismic modeling, boundary processing is particularly important due to the presence of surface waves. The Perfectly Matched Layer (PML) method is an efficient way of attenuating b...
