Reconstructing surface eruptive sequence of 2018 small phreatic eruption of Iwo-yama volcano, Kirishima Volcanic Complex, Japan, by infrasound cross-correlation analysis

open access: yesEarth, Planets and Space, 2021
The Iwo-yama volcano of the Kirishima Volcanic Complex in Japan had a small phreatic eruption in April 2018, which newly formed multiple vents. The activity was recorded by two infrasound sensors and two monitoring cameras, which had been installed ...

Detection of Infrasound By The Atlantic Cod [PDF]

open access: yesJournal of Experimental Biology, 1986
Below about 50 kHz the level of ambient noise in the sea increases continuously towards lower frequencies. In the infrasound range the spectral slope is particularly steep. This low-frequency noise may propagate long distances with little attenuation, causing a directional pattern of infrasound in the sea.

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.

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 ...

Detection of Infrasound in Fish and Behavioral Responses to Intense Infrasound in Juvenile Salmonids and European Silver Eels: A Minireview

open access: yes, 2001
his paper reviews recent studies of infrasound detection in fish and the use if intense infrasound as a fish deter-rent. The possible use of intense infrasound in acoustic fish barriers is discussed. Fish are sensitive to infrasound (

Possibility of the use of data of infrasonic monitoring for identification of the nature of seismic events

open access: yesГеофизический журнал, 2015
The paper considers the possibility of the use of infrasound measurements conducted in Ukraine to verify the recorded seismic events and the use of infrasound data as one of the criteria for their identification.

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.

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 ...
