Autocorrelation Infrasound Interferometry [PDF]

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 as a Cue for Seabird Navigation

Frontiers in Ecology and Evolution, 2021
Seabirds are amongst the most mobile of all animal species and spend large amounts of their lives at sea. They cross vast areas of ocean that appear superficially featureless, and our understanding of the mechanisms that they use for navigation remains ...

Tracking a Rangeland Fire With Infrasound Arrays

Geophysical Research Letters
We present the first infrasound analyses of a rangeland fire and demonstrate infrasound's potential in monitoring wildland fires. We recorded a prescribed fire in sagebrush steppe in cool, moist conditions, using eight infrasound arrays of diverse size ...

High-speed echoes in the polar winter mesosphere: Infrasound as a probable cause [PDF]

, 2023
We considered three events on 4 November 2015, 22 December 2016, and 12 November 2018, when the signals travelling in the polar winter mesosphere with high horizontal velocities above 300 m/s were measured by the atmospheric radar ESRAD (Chilson et al ...

Exploring Background Noise With a Large‐N Infrasound Array: Waterfalls, Thunderstorms, and Earthquakes

Geophysical Research Letters, 2023
Ambient infrasound noise contains an abundance of information that is typically overlooked due to limitations of typical infrasound arrays. To evaluate the ability of large‐N infrasound arrays to identify weak signals hidden in background noise, we ...

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.

SilberPrime/infrasound-signal-arrival-azimuth: v2.7.1

, 2021
This release includes the Matlab functions that calculate the infrasound signal arrival parameters: distance in km and degrees, back azimuth, and arrival times for three main propagation channels (tropospheric, stratospheric, thermospheric ...

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 ...

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.

International Monitoring System infrasound data products for atmospheric studies and civilian applications [PDF]

Earth System Science Data, 2022
The International Monitoring System (IMS) was established in the late 1990s for verification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Upon completion, 60 infrasound stations distributed over the globe will monitor the Earth's atmosphere for ...
