Radar‐Based Deep Learning for Debris Flow Identification Amid the Environmental Disturbances
Geophysical Research Letters, Volume 52, Issue 2, 28 January 2025.Abstract Microwave radar, utilizing the differences in Doppler frequencies from moving target echoes, offers remote sensing capabilities and continuous all‐weather monitoring for geological disasters. However, intelligent identification of debris flow signals using such radar remains unexplored. Therefore, we implemented 12 deep learning models coupled

ANOMALOUS SEISMO-ACOUSTIC WAVE PROPAGATION AND DETERMINATION SOURCE OF INFRASOUND
Proceedings of the Mongolian Academy of Sciences, 2017 The network of infrasound stations (I34MN) in Mongolia daily registers set of infrasound from various sources besides explosions. The data from explosions in mines in region and from other sources detected since 2000 to 2009 in seismic and infrasound ...

Is infrasound perceived by the auditory system through distortions?
Acta Acustica, 2021 Several studies showed that the human auditory system is sensitive to infrasound. The present study investigated if non-linear processes within the ear generate distortion products, which may explain the auditory sensitivity to infrasound.

Optical Observations of Meteors Generating Infrasound - II: Weak Shock Theory and Validation [PDF]
, 2014 We have recorded a dataset of 24 centimeter-sized meteoroids detected simultaneously by video and infrasound to critically examine the ReVelle [1974] weak shock meteor infrasound model. We find that the effect of gravity wave perturbations to the wind field and updated absorption coefficients in the linear regime on the initial value of the blast ...

Infrared barriers as a detection tool to reduce human–elephant conflicts
Wildlife Biology, Volume 2025, Issue 1, January 2025.Elephant incursions into farms represent an important challenge for local communities and farmers living around protected areas, but also for the long‐term conservation of elephants. Early detection of elephants is a promising technique to reduce elephant presence in farms and human settlements reducing human–elephant interactions.

Seismic Signatures of Fluctuating Fragmentation in Volcanic Eruptions
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 1, January 2025.Abstract Fragmentation plays a critical role in eruption explosivity by influencing the eruptive jet and plume dynamics that may initiate hazards such as pyroclastic flows. The mechanics and progression of fragmentation during an eruption are challenging to constrain observationally, limiting our understanding of this important process.

Weather Radar Detection and Analysis of Bolides in the Day or Night
Advances in Astronomy, Volume 2025, Issue 1, 2025.Weather radars have proven to be valuable tools for detection and analysis of meteorite falls, specifically identifying and analyzing falling meteorites which have survived the initial fireball. The NEXRAD system has been in operation since the late 1990s by the United States National Oceanic and Atmospheric Administration (NOAA).

Generation of Infra sound to replicate a wind turbine [PDF]
arXiv, 2018 We have successfully produced infrasound, as a duplicate of that produced by Industrial Wind Turbines. We have been able to produce this Infrasound inside a research chamber, capable of accommodating a human test subject. It is our vision that this project will permit others, with appropriate medical training and ethical oversight, to research human ...
