Study on Optimization of Infrasound Filtering Method for Coal Sample Failure under Load

open access: yesFrontiers in Earth Science, 2022
Effective filtering of the infrasound signal generated by coal samples is the basis for realizing the prediction of the infrasound of coal sample damage.

Evidence for a meteoritic origin of the September 15, 2007, Carancas crater [PDF]

open access: yes, 2008
On September 15th, 2007, around 11:45 local time in Peru, near the Bolivian border, the atmospheric entry of a meteoroid produced bright lights in the sky and intense detonations. Soon after, a crater was discovered south of Lake Titicaca. These events

An Easy Method to Sample Headspace Pheromones in the Field

open access: yesEthology, Volume 132, Issue 5, Page 365-371, May 2026.
Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.

Updated Global Reference Models of Broadband Coherent Infrasound Signals for Atmospheric Studies and Civilian Applications

open access: yesEarth and Space Science, 2022
The International Monitoring System (IMS) infrasound network has been established to detect nuclear explosions and other signals of interest embedded in the station‐specific ambient noise. The ambient noise can be separated into coherent infrasound (e.g.,

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

open access: yesThe Anatomical Record, Volume 309, Issue 4, Page 912-929, April 2026.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Study on precursory characteristics of granite failure based on infrasonic energy

open access: yesResults 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.

OH Airglow for Ionospheric Seismology Applications—From Instrumental Noise Characterization to Rayleigh Waves Detection Threshold

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Airglow layers are powerful tracers of upper‐atmosphere dynamics because of their sensitivity to a broad spectrum of atmospheric wave phenomena. Seismic activity, and in particular Rayleigh waves, constitutes a forcing mechanism capable of generating infrasonic waves in the atmosphere.

Infrasound exposure is linked to aversive responding, negative appraisal, and elevated salivary cortisol in humans

open access: yesFrontiers in Behavioral Neuroscience
IntroductionInfrasound describes sound wave frequencies below 20 Hz, which are typically imperceptible to humans. Some animals perceive and demonstrate aversion to infrasound, raising concerns about its potential adverse effects as an anthropogenic ...

Infrasound measurement system for real-time in situ tornado measurements

open access: yesAtmospheric Measurement Techniques, 2022
. Previous work suggests that acoustic waves at frequencies below human hearing (infrasound) are produced during tornadogenesis and continue through the life of a tornado, which have potential to locate and profile tornadic events and provide a range of ...

Characterization and Localization of Chemical Explosions and Lightning Flashes by a Flotilla of Stratospheric Balloons

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract On 3 August 2021, a flotilla of four Heliotrope solar hot air balloons was launched from central New Mexico (USA). The balloons, equipped with microbarometers, flew from sunrise to sunset at altitudes between 17 and 22 km. During the flight, eight chemical explosions ranging from 45 to 136 kg TNT equivalent and a thunderstorm occurred in the ...
