Infrasound is increasing applied as a tool to investigate magma dynamics at active
volcanoes, especially at open-vent volcanoes, such as Mt. Etna (Italy), which are prodigious …

Highly periodic 'drumbeat'long period (LP) earthquakes have been described from several
andesitic and dacitic volcanoes, commonly accompanying incremental ascent and effusion …

The Fourier transform remains one of the most popular spectral methods in time-series
