Ambient noise multimode surface wave tomography

Progress in Earth and Planetary Science
Seismic techniques using earthquakes are powerful tools for exploring the Earth’s internal structure. However, the earthquake distribution limits the spatial resolution.

The CRESCENT Generation 0 Cascadia Community Velocity Model: Constraints From the Joint Inversion of Teleseismic Receiver Functions and Ambient Noise Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract The Cascadia subduction zone can produce M9+ megathrust and M6.5+ intraplate earthquakes, motivating the need for a detailed 3‐D model of seismic properties at scales relevant to regional geology, basins, and infrastructure. To construct the Generation 0 Cascadia Region Earthquake Science Center Community Velocity Model (CRESCENT CVM), we ...

Block Kinematics, Interseismic Coupling and Fault Slip Rates in the Aegean Region From GPS and Earthquake Slip Vector Data: 1. Upper Plate Structures

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract We represent the active deformation of the Aegean region with an elastic‐kinematic block model composed of a finite number of rotating crustal blocks whose boundaries coincide with major active structures. A total of 832 GPS velocities and 146 earthquake slip vectors were inverted to provide estimates of block rotations and interseismic ...

Seismic interferometry applied to regional and teleseismic events recorded at Planchón-Peteroa Volcanic Complex, Argentina-Chile

, 2020
The Planchon-Peteroa Volcanic Complex (PPVC) is located in the Central Andes, Argentina-Chile. Even though this active volcanic system is considered one of the most dangerous volcanoes in the region, with more than twenty modest (VEI Seismic ...

A Plate‐Based Model for Reconciling Geodetic and Geologic Vertical Deformation Across Taiwan

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Reconciling geodetic and geologic deformation remains a fundamental challenge in tectonic studies of active orogens. Elastic rebound theory posits that present‐day deformation differs from deformation recorded over time scales longer than the earthquake cycle because locked faults store and release strain.

Adaptation of Iterative Supervirtual Interferometry for Enhancing Higher Modes From Surface Waves

Geophysical Prospecting, Volume 74, Issue 6, July 2026.
ABSTRACT For geotechnical applications, surface‐wave methods are one of the most important techniques for gathering information about the strength of the near surface, but these methods are sensitive to noise. Often only the fundamental mode is considered, but higher modes can also provide more information on deeper parts of the subsurface.

Comparison of MASW and seismic interferometry with use of ambient noise for estimation of S-wave velocity field in landslide subsurface

Acta Geophysica, 2019
This study presents a comparison of data acquisition, processing and interpretation between passive seismic interferometry (SI) and active multichannel analysis of surface waves (MASW) methods, both using surface waves for estimation S-wave velocity ...
