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

Rigidity Strengthening of Landslide Materials Measured by Seismic Interferometry
Remote 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

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

Review of progress in passive seismic reflection exploration
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.

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.
