Train Traffic as a Powerful Noise Source for Monitoring Active Faults With Seismic Interferometry

Geophysical Research Letters, 2019
Laboratory experiments report that detectable seismic velocity changes should occur in the vicinity of fault zones prior to earthquakes. However, operating permanent active seismic sources to monitor natural faults at seismogenic depth is found to be ...

High‐Rate GNSS Analysis of the Onset, Growth, and Termination of Slow Slip Events and Their Along‐Dip Variability Offshore the Boso Peninsula, Japan (2011–2024)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Recurring slow slip events (SSEs) with moment magnitudes in the mid‐6 range have occurred every few years since the 1990s offshore the Boso Peninsula, Japan. These events occur near the source area of ∼M8 megathrust earthquakes beneath the Tokyo metropolitan area and are accompanied by earthquake swarms.

Evaluating Seismic Ambient Noise Techniques for Detecting Ice‐Bearing Rocks on the Moon

Earth and Space Science
One of the primary objectives of upcoming lunar missions is to locate ice‐bearing rocks at the South Pole. While evidence for their presence exists, the exact distribution and quantity remain uncertain. In this study, we evaluate the potential of seismic

The application of seismic interferometry for estimating a 1D S-wave velocity model with the use of mining induced seismicity

Journal of Sustainable Mining, 2018
The main objective of this paper is to present the usefulness of the seismic interferometry method to determine the S-wave velocity model of the rock mass affected by exploitation in the KGHM Rudna copper ore mine.

Tidal Response of Seismic Wave Velocity at Shallow Crust in Japan

Geophysical Research Letters, 2023
Microcracks in geomaterials cause variations in the elastic moduli under applied strain, thereby creating seismic wave velocity variations. These are crucial for understanding the dynamic processes of the crust, such as fault‐zone damage, healing, and ...

Seismic interferometry with antipodal station pairs [PDF]

Geophysical Research Letters, 2013
In this study, we analyze continuous data from all Global Seismographic Network stations between year 2000 and 2009 and demonstrate that several body wave phases (e.g., PP, PcPPKP, SKSP, and PPS) propagating between nearly antipodal station pairs can be clearly observed without array stacking using the noise/coda cross‐correlation method.

Geodetic Constraints on Fault Kinematics and Dynamics of 2021 Maduo Earthquake: Implications for Fault Friction

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Postseismic afterslip has been inferred to occur on fault barriers surrounding coseismic asperities, which can be explained by velocity‐strengthening friction in barriers and velocity‐weakening friction in asperities. However, afterslip also exhibits spatial overlap with coseismic slip for some events.

Role of Volcano‐Tectonic Interactions During Early‐Phase Magma‐Assisted Continental Rifting

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract We study volcanic‐tectonic interactions during the early phase of rifting in the Natron Rift, a magmatic segment of the East African Rift System. We use the open‐source crustal deformation modeling code, PyLith, to model deflation during the 2007–2008 explosive eruptions and inflation during 2016–2023.
