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.

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

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 ...

Infrasound radiation of cyclones
The Journal of the Acoustical Society of America, 2005Tropical cyclones produce strong perturbations of atmosphere and the ocean surface accompanied by acoustical radiation. Infrasonic signals in the 0.1−0.5 frequency band can be observed at distances of thousands of miles from the cyclone. The effect of infrasound radiation is connected apparently to the interaction of the counter-propagating sea-surface

Ambient Infrasound Noise, Station Performance, and Their Relation to Land Cover across Alaska
Seismological Research Letters, 2022The 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 ...

The distortion of pure tones (1–16 Hz) caused by the nonlinearities of the middle ear was calculated. It is shown that the slope of the audibility curves for infrasound of Yeowart and Evans could be predicted, thus implying that infrasound might not be heard in the normal sense, but only heard as distortion after being transduced through the middle ear.

Infrasound signals in simulated nontornadic and pre-tornadic supercells.
Journal of the Acoustical Society of America, 2022There has been increased interest in improving severe weather detection by supplementing the conventional operational radar network with an infrasound observation network, which may be able to detect distinct sub-audible signatures from tornadic ...

At the present developed procedures of evaluation of annoyance of low frequency noise (LFN) on human and occupational health are based on international standards, ISO 7196 and ISO 9612. These standards are based on levels of thresholds of the human auditory system and subjective observations of vibrations of human body impacted by infrasound waves.

Infrasound From a Buried Chemical Explosion Recorded on a Balloon in the Lower Stratosphere
Geophysical Research Letters, 2021Infrasound waveforms generated by natural and anthropogenic phenomena contain important clues about the size and nature of the event. We show that sensors on balloons in the lower stratosphere can record faithful representations of the near‐source ...
