Synthetic Hybrid Broadband Seismograms Based on InSAR Coseismic Displacements [PDF]

Bulletin of the Seismological Society of America, 2014
Abstract Conventional acceleration records do not properly account for the observed coseismic ground displacements, thus leading to an inaccurate definition of the seismic demand needed for the design of flexible (long period) structures. Large coseismic displacements observed during the 27 February 2010 Maule earthquake suggest that this effect ...

An empirical tool for predicting the presence or absence of coseismic displacements at GNSS stations [PDF]

GPS Solutions
AbstractUnmodeled displacements in GNSS times series, induced by instrumental artifacts or geophysical events, create significant biases in station trajectory parameters that can propagate into the reference frame itself. While non-tectonic ‘jumps’, such as equipment changes, affect only a specific GNSS station, seismically-induced displacements can ...

Large coseismic displacements and tall buildings

The Structural Design of Tall and Special Buildings, 2011
SUMMARYSeismic demands imposed on tall buildings are sensitive to long‐period ground motions. A source of these motions can be near‐fault effects: rupture directivity and fling step (large coseismic displacements). The potential adverse effects of near‐fault motions on structures have been attributed to rupture directivity in previous studies. However,

Error Propagation Analysis in Three-Dimensional Coseismic Displacement Inversion

IEEE Geoscience and Remote Sensing Letters, 2014
Using the Bam earthquake as an example, we apply the multiple-aperture interferometry (MAI) algorithm to measure the azimuth (AZI) displacement with multiple mode synthetic aperture radar (SAR) images (ScanSAR and image modes) and further on produce the 3-D coseismic displacement maps using well-known models: multiple independent interferometric SAR ...

Measuring Coseismic Displacements With Point-Like Targets Offset Tracking

IEEE Geoscience and Remote Sensing Letters, 2014
Offset tracking is an important complement to measure large ground displacements in both azimuth and range dimensions where synthetic aperture radar (SAR) interferometry is unfeasible. Subpixel offsets can be obtained by searching for the cross-correlation peak calculated from the match patches uniformly distributed on two SAR images.

Regression models for estimating coseismic landslide displacement

Engineering Geology, 2007
Newmark's sliding-block model is widely used to estimate coseismic slope performance. Early efforts to develop simple regression models to estimate Newmark displacement were based on analysis of the small number of strong-motion records then available. The current availability of a much larger set of strong-motion records dictates that these regression

Comparison of Coseismic Displacement Obtained from GEONET and Seismic Networks

Journal of Earthquake and Tsunami, 2016
It is generally recognized that permanent displacements estimated by the double integration of acceleration records need a suitable baseline correction. Current baseline correction methods have been validated by comparing the displacements with those from the Global Positioning System (GPS) records nearby, but GPS stations that are sufficiently close ...
