Coseismic surface deformation from air photos: The Kickapoo step over in the 1992 Landers rupture [PDF]
, 2006 Coseismic deformation of the ground can be measured from aerial views taken before and after an earthquake. We chose the area of the Kickapoo-Landers step over along the 1992 Landers earthquake zone, using air photos (scale 1:40,000) scanned at 0.4 m ...

Progress in Earth and Planetary Science, 2018 Seismic interferometry is one of the most effective techniques for detecting temporal variations in seismic velocity caused by large earthquakes. Before the 2011 Tohoku-Oki earthquake (M w 9.0) near the Japan Trench, a slow slip event (SSE, M w 7.0) and ...

Passive Seismic Interferometry for Subsurface Imaging
, 2015 Seismic interferometry is a method that allows the retrieval of the seismic response at one receiver from a virtual source at the position of another receiver. The method was first proposed in the seismic exploration community by Claerbout (1968) for a horizontally layered subsurface.

Universitas Scientiarum, 2019 The estimation of static corrections is an issue still unsolved for PS converted wave processing. Due to the PS converted wave usually arriving at the surface at non-zero angles, the surface consistent approach is no longer valid, and corrections ...

Improving Surface Wave Retrieval From Traffic Noise by Deconvolution of the Decomposed Wavefield
Earth and Space Science, 2023 Traffic noise is an important type of passive seismic data because it usually includes strong dispersive surface wave components and can be easily accessed.
