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.

UAS‐Based Observations of Infrasound Directionality at Stromboli Volcano, Italy

Geophysical Research Letters, 2023
Infrasound (low frequency sound waves) can be used to monitor and characterize volcanic eruptions. However, infrasound sensors are usually placed on the ground, thus providing a limited sampling of the acoustic radiation pattern that can bias source size

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 ...

Evaluation of infrasound sensors [PDF]

, 1998
Sandia is evaluating the performance of various infrasound sensors that could be used as part of the International Monitoring Systems (IMS). Specifications for infrasound stations are outlined in CTBT/PC/II/1/Add.2.

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 ...

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.

The Mount Meron infrasound array: an infrasound array without a noise reduction system [PDF]

Geophysical Journal International, 2019
SUMMARYMeasurements of seismo-acoustic events by collocated seismic and infrasound arrays allow for studying the two wavefields that were produced by the same event. However, some of the scientific and technical constraints on the building of the two technologies are different and may be contradicting.

Head and Whisker Behaviours Observed During Foraging in Northern Elephant Seals (Mirounga angustirostris)

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We observed a range of behaviours during foraging, including forward swimming, vertical diving, swooping, dabbing, sweeping and rotations. Head dabbing was also sometimes accompanied by the seal producing infrasounds, the bouts of which coincided with rhythmic whisker protractions. ABSTRACT Pinnipeds use their whiskers to detect and follow hydrodynamic

An Analysis of Dense Seismoacoustic Signals from an Accidental Chemical Explosion in South Korea on 4 March 2020

The Seismic Record
On 4 March 2020, an accidental explosion occurred at a chemical plant in South Korea, generating both seismic and infrasound signals, which were recorded by multiple sensors at distances as great as 400 km across the southern Korean Peninsula.

Effects of Discharge and Morphology on Fluvial Sound

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Toward developing acoustic monitoring for stream gauging applications, we show the dependence of stream sounds on discharge and morphology in field and lab studies. Currently, there is need for innovative, non‐invasive, and low‐cost methods of surface freshwater discharge monitoring, and recording aerial fluvial sounds could be used ...
