High-resolution lithospheric imaging with seismic interferometry
In recent years, there has been an increase in the deployment of relatively dense arrays of seismic stations. The availability of spatially densely sampled global and regional seismic data has stimulated the adoption of industry-style imaging algorithms applied to convertedand scattered-wave energy from distant earthquakes, leading to relatively high-resolution images of the lower crust and upp...
متن کاملHigh-resolution seismic reflection to image hydrogeologic sequences
Introduction High-resolution seismic reflection has been successfully used to delineate preferential pathways within groundwater systems that represent corridors for contaminant movement in a wide variety of challenging hydrologic settings, many in settings where other methods and/or monitor wells have not been enlightening. For more than four decades, seismic reflection has found utility addre...
متن کاملHigh-resolution probing of inner core structure with seismic interferometry
Increasing complexity of Earth’s inner core has been revealed in recent decades as the global distribution of seismic stations has improved. The uneven distribution of earthquakes, however, still causes a biased geographical sampling of the inner core. Recent developments in seismic interferometry, which allow for the retrieval of core-sensitive body waves propagating between two receivers, can...
متن کاملHigh-resolution surface-wave tomography from ambient seismic noise.
Cross-correlation of 1 month of ambient seismic noise recorded at USArray stations in California yields hundreds of short-period surface-wave group-speed measurements on interstation paths. We used these measurements to construct tomographic images of the principal geological units of California, with low-speed anomalies corresponding to the main sedimentary basins and high-speed anomalies corr...
متن کاملParameterisation of Point Bars in High- Resolution Seismic Data
We developed a simple method to parameterise fluvial point bars, which are common sedimentary deposits in meandering river environments. The method needs four points defining the point bar and is based on high-resolution seismic data. A model geometry is compared with the real point bar geometry. We optimise the model parameters by minimizing the error in the area covered by both objects. The m...
