Moho topography beneath the European Eastern Alps by global-phase seismic interferometry

open access: yes, 2021
. In this work we present the application of the global-phase seismic interferometry (GloPSI) technique to a dataset recorded across the Eastern Alps with the EASI (Eastern Alpine Seismic Investigation) temporary seismic network. GloPSI aims at rendering

Optimized workflows for high-frequency seismic interferometry using dense arrays

open access: yesGeophysical Journal International, 2021
High-frequency seismic surface waves sample the top few tens of meters to the top few kilometres of the subsurface. They can be used to determine 3-D distributions of shear-wave velocities and to map the depths of discontinuities (interfaces) within ...

Structural change detection applying long-term seismic interferometry by deconvolution method to a modern civil engineering structure (New Zealand)

open access: yesBulletin of Earthquake Engineering, 2021
Pulse-wave propagation velocity and resonance frequency measured in civil engineering structures are both related to structural design. Monitoring their variation following seismic strong shaking provides information about the immediate building capacity.

Rigidity Strengthening of Landslide Materials Measured by Seismic Interferometry

open access: yesRemote Sensing, 2021
Landslides have caused extensive infrastructure damage and caused human fatalities for centuries. Intense precipitation and large earthquakes are considered to be two major landslide triggers, particularly in the case of catastrophic landslides. The most

An aseismic slip pulse in northern Chile and along-strike variations in seismogenic behavior [PDF]

open access: yes, 2006
We use interferometric synthetic aperture radar, GPS, and seismic observations spanning 5 to 18 years to reveal a detailed kinematic picture of the spatiotemporal evolution of fault slip in a region corresponding to the 30 July 1995 M_w 8.1 subduction ...

Towards real-time assessment of convergence criteria in seismic interferometry: Selective stacking of cross-correlations at the San Emidio geothermal field

open access: yes, 2021
Seismic field logistics, particularly recording geometry and duration, can be made significantly more efficient in ambient-noise interferometry if strategies for ensuring timely convergence of Empirical Green's Functions (EGFs) can be devised ...

Review of Seismic Interferometry

open access: yesChigaku Zasshi (Jounal of Geography), 2008
We review seismic interferometry with an example of a numerical simulation. A cross-correlation of two seismic records at different receivers yields a virtual source record that corresponds to the seismic response observed at one receiver due to the source at another receiver location.

Review of progress in passive seismic reflection exploration

open access: yes地球与行星物理论评, 2023
Seismic exploration is a key method for the study of underground structures. Active seismic surveys can acquire high signal-to-noise ratio reflection data; however, the operation of active seismic surveys is complicated, and the exploration cost is high.

Near-surface structure of the Sodankylä area in Finland, obtained by passive seismic interferometry [PDF]

open access: yesSolid Earth, 2021
Controlled-source seismic exploration surveys are not always possible in nature-protected areas. As an alternative, the application of passive seismic techniques in such areas can be proposed.

Lab and Field Tests of a Low‐Cost 3‐Component Seismometer for Shallow Passive Seismic Applications

open access: yesEarth and Space Science, 2023
We performed laboratory tests and field surveys to evaluate the performance of a low‐cost 3‐component seismometer, consisting of three passive electromagnetic spring‐mass sensors, whose 4.5 Hz natural frequency is extended down to 0.5 Hz thanks to hyper ...
