Velocity changes after the 2021 MS 6.4 Yangbi earthquake based on passive image interferometry

Frontiers in Earth Science, 2023
An MS 6.4 earthquake occurred in Yangbi, Yunan Province, China, on 21 May 2021. The epicenter was on the blind branch fault in the west of the Weixi–Qiaohou–Weishan fault, but no surface rupture was obvious.

The Effects of Carbonate Precipitation on the Physical Properties of Basalt

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract To avoid the negative consequences of climate change, there is an urgent need to remove carbon dioxide from the atmosphere. Carbon mineralization—the conversion of injected CO2 into stable carbonate minerals—offers a promising pathway for large‐scale, permanent geologic storage. While projects such as CarbFix have demonstrated its feasibility,

Evaluating Seismic Ambient Noise Techniques for Imaging Lava Tubes on the Moon

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Detecting and characterizing lava tubes is a key objective of upcoming lunar missions. While evidence for their presence exists, their precise dimensions and depths remain uncertain. This study evaluates the potential of seismic ambient noise methods, such as seismic interferometry, H/V spectral ratios, distributed acoustic sensing (DAS), and ...

Monitoring rapid temporal change in a volcano with coda wave interferometry [PDF]

Geophysical Research Letters, 2005
Multiply–scattered waves typically dominate the late part of the seismic coda in local earthquake seismograms. Small medium changes that have no detectable influence on the first arrivals are amplified by multiple scattering and may thus be readily observed in the coda.

Monitoring Groundwater Pumping Using Time‐Lapse Tomography From Ambient Seismic Noise

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Management of water resources will be of critical importance as the effects of climate change accelerate. This implies the need to monitor water resources with high spatial and temporal resolution. One way to meet this need could be passive seismic methods using ambient seismic noise. In this study, we present a novel approach using time‐lapse

Hayward Fault Creep From Coda Wave Interferometry

Geophysical Research Letters
Abstract Understanding creep is essential for assessing seismic hazards along the creeping Hayward Fault, which threatens the San Francisco area. Current 1‐D monitoring methods, like creepmeters and theodolites, provide limited measurements with low spatial resolution.

Seismic source displacement by coda wave interferometry at Soufrière Hills Volcano, Montserrat, WI [PDF]

Natural Hazards and Earth System Sciences, 2009
Since the start of the ongoing eruption, on 18 July 1995, the Soufrière Hills Volcano (SHV) on Montserrat, WI, has been monitored with a network of seismometers providing an unparalleled wealth of observations.

Nonlinear coda wave interferometry for the global evaluation of damage levels in complex solids

Ultrasonics, 2017
A nonlinear acoustic method to assess the damage level of a complex medium is discussed herein. Thanks to the highly nonlinear elastic signatures of cracks or, more generally, internal solid contacts, this method is able to distinguish between contributions from linear wave scattering by a heterogeneity and contributions from nonlinear scattering by a ...
