Rapid Seismic and Infrasound Assessment of Large Landslides: A Case Study From Denali National Park and Preserve (Alaska)

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract Large, rapid landslides are a global hazard that can occur in remote, mountainous areas. Eyewitness reports of landslides and satellite imagery can often be limited or delayed, particularly during inclement weather. However, landslide‐generated seismic and infrasound (low‐frequency atmospheric sound) waves can be remotely detected in near real‐

A simple method to evaluate the air-to-ground coupling efficiency: a tool helping the assessment of seismic/infrasonic energy partitioning during an eruption

Earth, Planets and Space, 2021
A volcanic eruption transmits both seismic and infrasound signals. The seismo-acoustic power ratio is widely used to investigate the eruption behaviors and the source dynamics.

Existing Soundscapes and the Impact of Noise on the Welfare of Farmed Salmonids: A Review

Reviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT Understanding how farmed salmonids sense and respond to their environment is key to securing animal welfare and efficient production. However, hearing has rarely received attention, despite the omnipresence of underwater sound and its potential effects.

The Dominant Source Mechanism of Infrasound Generation in Powder Snow Avalanches

Geophysical Research Letters
Powder snow avalanches (PSAs) radiate infrasound energy, yet the source mechanism remains unclear, limiting hazard monitoring and mitigation with infrasound‐based technologies.

ANOMALOUS SEISMO-ACOUSTIC WAVE PROPAGATION AND DETERMINATION SOURCE OF INFRASOUND

Proceedings of the Mongolian Academy of Sciences, 2017
The network of infrasound stations (I34MN) in Mongolia daily registers set of infrasound from various sources besides explosions. The data from explosions in mines in region and from other sources detected since 2000 to 2009 in seismic and infrasound ...

UAS‐Based Observations of Infrasound Directionality at Stromboli Volcano, Italy

Geophysical Research Letters, 2023
Infrasound (low frequency sound waves) can be used to monitor and characterize volcanic eruptions. However, infrasound sensors are usually placed on the ground, thus providing a limited sampling of the acoustic radiation pattern that can bias source size

Radiosonde‐to‐Space (R2S) Atmospheric Specifications: Bridging Observations and Models for Infrasound Propagation

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Infrasound propagation is inherently asymmetric and time‐dependent, making accurate atmospheric specifications essential for predicting when and where signals arrive. The Naval Research Laboratory's Ground‐to‐Space (G2S) model is widely used for this purpose, yet discrepancies between G2S predictions and observations highlight the need for ...

Rocket Launch Detection with Smartphone Audio and Transfer Learning

Signals
Rocket launches generate infrasound signatures that have been detected at great distances. Due to the sparsity of the networks that have made these detections, however, most signals are detected tens of minutes to hours after the rocket launch.
