Study on the Coupling Characteristics of Infrasound–Temperature–Gas in the Process of Coal Spontaneous Combustion and a New Early Warning Method

Combustion Science and Technology, 2023
The phenomenon of coal spontaneous combustion poses a serious threat to mine safety, and monitoring and warning of coal spontaneous combustion has become an important issue that needs to be urgently addressed in coal mines.

Using Local Infrasound to Estimate Seismic Velocity and Earthquake Magnitudes

Bulletin of The Seismological Society of America (BSSA), 2023
Earthquake ground motions in the vicinity of receivers couple with the atmosphere to generate pressure perturbations that are detectable by infrasound sensors.

Characterizing Infrasound Station Frequency Response Using Large Earthquakes and Colocated Seismometers

Bulletin of The Seismological Society of America (BSSA), 2023
Earthquakes generate infrasound in multiple ways. Acoustic coupling at the surface from vertical seismic velocity, termed local infrasound, is often recorded by infrasound sensors but has seen relatively little study.

Evolving infrasound measurement and growing infrasound monitoring network

INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2023
Infrasound carries information useful for detecting a strong natural phenomenon such as volcanic eruption and tsunami, which may cause catastrophic disaster. Therefore, infrasound measurement is gathering attention for potential applications in disaster prevention and life protection.

The Hunga Tonga–Hunga Ha’apai Eruption of 15 January 2022: Observations on the International Monitoring System (IMS) Hydroacoustic Stations and Synergy with Seismic and Infrasound Sensors

Seismological Research Letters, 2022
Examination of the International Monitoring System (IMS) hydroacoustic data recorded during the 15 January 2022 eruption of the Hunga Tonga–Hunga Ha’apai (HTHH) volcano shows that the in-water hydroacoustic sensors recorded a long-duration (40 min ...

Atmospheric Infrasound

Physics Today, 2000
Imagine a world in which you could hear not just nearby conversations and the noise of traffic a few blocks away, but also the sound of blasting in a quarry in the next state, the rumblings of an avalanche or volcano a thousand miles away, and the roar of a typhoon halfway around the world. Fortunately, nature has spared our senses from direct exposure

Bolide Infrasound Signal Morphology and Yield Estimates: A Case Study of Two Events Detected by a Dense Acoustic Sensor Network

Astronomical Journal
Two bolides (2016 June 2 and 2019 April 4) were detected at multiple regional infrasound stations, with many of the locations receiving multiple detections.

Ambient Infrasound Noise, Station Performance, and Their Relation to Land Cover across Alaska

Seismological Research Letters, 2022
The addition of 108 infrasound sensors—a legacy of the temporary USArray Transportable Array (TA) deployment—to the Alaska regional network provides an unprecedented opportunity to quantify the effects of a diverse set of site conditions on ambient ...
