Uncertainty Quantification for Infrasound Propagation in the Atmospheric Environment

Applied Sciences, 2022
The propagation of infrasound in the atmosphere is influenced by atmospheric environmental parameters, which affect the precise localization of the infrasound source. Therefore, it has become crucial to quantify the influence of atmospheric environmental

Autocorrelation Infrasound Interferometry

Journal of Geophysical Research: Solid Earth, 2021
AbstractSeismic and infrasound multistation ambient‐noise interferometry has been widely used to infer ground and atmospheric properties, and single‐station and autocorrelation seismic interferometry has also shown potential for characterizing Earth structure at multiple scales.

Infrasound and seismoacoustic signatures of the 28 September 2018 Sulawesi super-shear earthquake [PDF]

Natural Hazards and Earth System Sciences, 2019
A magnitude 7.5 earthquake occurred on 28 September 2018 at 10:02:43 UTC near the city of Palu on the Indonesian island of Sulawesi. It was a shallow, strike-slip earthquake with a rupture extending to a length of about 150 km and reaching ...

Skyfall: Signal Fusion from a Smartphone Falling from the Stratosphere

Signals, 2022
A smartphone plummeted from a stratospheric height of 36 km, providing a near-real-time record of its rapid descent and ground impact. An app recorded and streamed useful internal multi-sensor data at high sample rates.

Processing of volcano infrasound using film sound audio post-production techniques to improve signal detection via array processing

Geoscience Letters, 2020
The use of infrasound for the early detection of volcanic events has been shown to be effective over large distances, and unlike visual methods, is not weather dependent.

A basic identification of late auditory evoked potentials at infrasound frequencies: Support neural network–based signal processing

Journal of Low Frequency Noise, Vibration and Active Control, 2023
Concerns about potential health risks from infrasound exposure require objective investigation methods for the perception of infrasound by humans. Neural-network methods were applied to identify weak infrasound evoked potentials and to investigate the ...

METHOD OF STUDYING INFRASOUND WAVES FROM THUNDERSTORMS

Solar-Terrestrial Physics, 2022
The paper provides an overview of studies of infrasound signals from thunderstorms over a period of more than 30 years. We deal with several types of infrasound signals from thunderstorms detected at the ISTP SB RAS infrasound station Badary in Buryatia.
