Automatic classification of volcanic tremor using Support Vector Machine

open access: yes, 2008
A system for automatic recognition of different volcanic activity regimes based on supervised classification of volcanic tremor is proposed. Spectrograms are calculated from volcanic tremor time-series, separated into four classes, each assumed as ...

Fracture mechanics of volcanic eruptions [PDF]

open access: yes, 2009
Seismology is a key tool in the forecasting of volcanic eruptions. The onset of an eruption is often preceded and accompanied by an increase in local seismic activity, driven by fracturing within the edifice.

Systematic mapping study: automatic recognition and localization of volcanic seismic events

open access: yesFrontiers in Earth Science
Active volcanoes represent a significant hazard to surrounding communities, requiring continuous and reliable monitoring. While seismic signals constitute the main source of information, each volcano produces massive datasets that are difficult to ...

Subband decomposition and reconstruction of continuous volcanic tremor

open access: yes, 2012
A new method of analyzing volcanic tremor is presented, which uses properties of undecimated wavelet packet transforms to filter, decompose, and recover signals from continuous multichannel data.

Volcanic Lakes

open access: yes, 2015
Volcanic lakes are amongst the most spectacular natural features on the planet. These intersections of magmatic-hydrothermal systems and the Earth’s surface are, poetically speaking, “blue windows” into the depth of a volcano (Fig. 1).

Volcanology of the Raventhorpe and Pokeno West Volcanic Complexes, South Auckland Volcanic Field [PDF]

open access: yes, 2012
The South Auckland volcanic field hosts at least 82 volcanic centres throughout the Pukekohe, Bombay, Tuakau, Pukekawa and Onewhero regions. The monogenetic basaltic volcanic field was active between 1.59 to 0.51 Ma, producing tuff rings, maar craters ...

Analysis of volcanic tremor during the 2021 Fagradalsfjall eruption

open access: yes, 2022
Volcanic tremors are low frequency seismic events, occurring prior to or during eruptions and are believed to be caused by the movement of magma. The study of those events can reveal subsurface processes during volcanic activity, furthermore it can help ...

Volcanic tremor location during the 2004 Mount Etna lava effusion

open access: yes, 2006
A lava emission started at Mt. Etna, Italy, on 7 September, 2004. Neither earthquake seismicity heralded or accompanied the opening of the fracture field from which the lava poured out, nor volcanic tremor changed in amplitude and frequency content ...

From Dome to Disease: The Respiratory Toxicity of Volcanic Cristobalite [PDF]

open access: yes, 2012
Exposure to fine-grained volcanic ash can potentially cause acute and chronic respiratory disease. The toxicity of ash is likely to vary depending on the type and style of eruption; eruptions at dome-forming volcanoes, in particular, can produce ash ...
