Since the 1919 foundation of the International Association of Volcanology and Chemistry of
the Earth's Interior (IAVCEI), the fields of volcano seismology and acoustics have seen …

Several sources of interest often generate both low‐frequency acoustic and seismic signals
due to energy propagation through the atmosphere and the solid Earth. Seismic and …

Over the past two decades (2000–2020), volcano infrasound (acoustic waves with
frequencies less than 20 Hz propagating in the atmosphere) has evolved from an area of …

Volcanic eruption columns typically have unsteady source conditions, where mass and heat
fluxes from the vent evolve or fluctuate on time scales from seconds to hours. However …

Infrasound data are used by scientists and monitoring observatories to track shifts in eruptive
behavior, identify signs of unrest, and ultimately help forecast major eruptions. However …

Infrasound signals are used to investigate and monitor active volcanoes during eruptive and
degassing activity. Infrasound amplitude information has been used to estimate eruptive …

Abstract The volcano of Hunga Tonga-Hunga Ha'apai in Tonga erupted on 15 January
2022, generating severe disturbances in the atmosphere and the ionosphere. This event …

Explosive volcanic eruptions radiate seismic waves as a consequence of pressure and
shear traction changes within the conduit/chamber system. Kinematic source inversions …

Laterally directed explosive eruptions are responsible for multiple fatalities over the past
decade and are an increasingly important volcanology problem. To understand the energy …

摘要声源识别与参数反演是次声探测应用的重点与难点, 研究次声非线性传播模型及其特征是
解决上述问题的关键点之一. 典型的次声能量传播路径包括平流层及热层折射波波导 …
