Infrasound early warning model for debris flow in a typical drainage basin in Beijing mountainous area

地质科技通报
Objective Infrasound is an effective approach for debris flow warning. Traditional threshold-based warning methods focus solely on individual infrasound characteristics, which can lead to false alarms or missed detections.

Study on precursory characteristics of granite failure based on infrasonic energy

Results in Physics, 2017
To study signal characteristics of precursory infrasound of granite failure, coal-rock stress loading device and infrasound acquisition device were adopted to perform infrasound test in uniaxial loading process for granite samples.

Effects of infrasound on the perception of a low-frequency sound

Acta Acustica, 2023
The study investigated the effects of an 8 Hz infrasound sinusoid, presented at a sensation level (SL) of 9 decibels (dB), on the detection of i) a 64 Hz pure tone and ii) an 8 Hz sinusoidal amplitude modulation imposed on a 64 Hz sinusoidal carrier ...

From Cohesion to Norms: How Animal Groups Come, Stay, and Function Together

Ethology, Volume 132, Issue 9, Page 604-622, September 2026.
The present review underscores two salient points: In the context of evolutionary transitions to pair‐ and group living, it is imperative to acknowledge the distinction between selective forces that act during the origin of these social systems and those that act during their subsequent maintenance.

Infrasound detection of approaching lahars

Scientific Reports, 2023
AbstractInfrasound may be used to detect the approach of hazardous volcanic mudflows, known as lahars, tens of minutes before their flow fronts arrive. We have analyzed signals from more than 20 secondary lahars caused by precipitation events at Fuego Volcano during Guatemala’s rainy season in May through October of 2022.

Seismic Tremor as a Precursor to Hydrothermal Explosions Near Mutnovsky Volcano (Kamchatka)

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Mutnovsky Volcano, ∼70 km SW of Petropavlovsk‐Kamchatsky, exhibits persistent degassing, hosts active hydrothermal springs and the Mutnovsky Geothermal Power Plant (MGPP) on its slopes. Using the network covariance matrix approach, we analyzed seismic data recorded in 2023–2024 by 15 seismic stations operating around Mutnovsky Volcano.

Estimating Surface Explosion Yield From Single‐Channel Infrasound Signals at Regional Distances With Random‐Forest Regression

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract When detonated on the Earth's surface, large explosions emit distinctive acoustic signatures that propagate over vast distances with relatively low attenuation in the form of infrasound. Infrasound stations hundreds of kilometers from the impulsive source can record the propagated pressure signal, atmospheric conditions permitting.

Research on the Response Characteristics and Identification of Infrasound Signals in the Jialongcuo Ice Avalanche, Tibet

Remote Sensing, 2023
Due to the inability of remote sensing satellites to monitor avalanches in real time, this study focuses on the glaciers in the rear edge of Jialongcuo, Tibet, and uses infrasound sensors to conduct real-time monitoring of ice avalanches.

A study on the effect of infrasound.

Nippon Jibiinkoka Gakkai Kaiho, 1989
In order to examine the influence of infrasound that is becoming topical in society, human beings and guinea pigs were exposed to infrasound. After exposure, the hearing level, vestibular functions and autonomic nervous functions of human beings were examined, and endocochlear potential (EP) and cochlear microphonics (CM) of guinea pigs were examined ...

Coupling UV Camera‐Derived SO2 Emission Rate and Thermal Output at Mount Etna: A Decadal Analysis Across Eruptive Phases

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract At persistently degassing open‐vent volcanoes, SO2 emissions are especially useful to capture the transition from quiescence to eruption, though accurate quantification is challenged by complex volcanic plume dynamics and limited resolution of observations. Here, we present an exceptionally long (∼10–year) record of SO2 emission rates from the
