Frequency‐Dependent Acoustic Reflection Coefficients of Flat Ground Assessed Using the Sonic Boom From the OSIRIS‐Rex Sample Return Capsule Recorded on Free Flying Balloons

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Low frequency sound can travel great distances in planetary atmospheres. When these waves reflect off the air/ground interface, energy may be absorbed or transferred to mechanical waves in the subsurface. This study describes the direct and reflected acoustic wave generated by the re‐entry of the OSIRIS‐REx Sample Return Capsule captured on a ...

The Dominant Source Mechanism of Infrasound Generation in Powder Snow Avalanches

Geophysical Research Letters
Powder snow avalanches (PSAs) radiate infrasound energy, yet the source mechanism remains unclear, limiting hazard monitoring and mitigation with infrasound‐based technologies.

Aerial and Space‐Borne Seismology on Venus: Viability and Design Implications for Future Missions

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Venus' evolution remains a mystery because of the lack of in situ geophysical data to constrain its interior structure. Recently‐selected planetary missions VERITAS (NASA), DAVINCI+ (NASA), and EnVision (ESA) will investigate the planet's interior, surface, and atmospheric chemistry.

Eruption Source Parameters in Volcanic Plume Modeling: Advances, Challenges, and Future Directions

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Accurately predicting the atmospheric dispersion of volcanic ash and gases is crucial for both scientific understanding and hazard mitigation. Estimating Eruption Source Parameters (ESP), such as mass eruption rate, plume height, duration, and particle size distribution and properties, remains challenging due to the complex nature of volcanic ...

A simple method to evaluate the air-to-ground coupling efficiency: a tool helping the assessment of seismic/infrasonic energy partitioning during an eruption

Earth, Planets and Space, 2021
A volcanic eruption transmits both seismic and infrasound signals. The seismo-acoustic power ratio is widely used to investigate the eruption behaviors and the source dynamics.

Unsupervised Deep Representation Learning for Infrasound Phase Identification

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Infrasound phase identification is challenging because atmospheric variability strongly influences signal propagation on short timescales that are not resolved by standard atmospheric models. While traditional approaches rely on propagation modeling and array‐derived parameters, recent work suggests that waveform structure itself encodes ...

Rocket Launch Detection with Smartphone Audio and Transfer Learning

Signals
Rocket launches generate infrasound signatures that have been detected at great distances. Due to the sparsity of the networks that have made these detections, however, most signals are detected tens of minutes to hours after the rocket launch.
