Abstract Despite Mt. Etna's long-standing reputation as an effusive volcano, since 1986
there has been an evident increase in mid-intensity explosive eruptions from its summit …

Volcanic tremor is often observed to be associated with an increase in volcanic activity and
during periods approaching eruptions. It is therefore of crucial importance to study this …

The accelerating growth of seismic unrest before eruptions has been observed at many
volcanoes and utilized for eruption forecasts. However, there are still many eruptions for …

Ground deformation in volcanic areas induced by geothermal fluid circulation can reveal
useful information about the dynamical processes occurring in the subsurface hydrothermal …

Seismic interferometry is a powerful tool to monitor the seismic velocity change associated
with volcanic eruptions. For the monitoring, changes in seismic velocity with environmental …

Résumé Identifying precursory phenomena is central to the short-range assessment and
anticipation of volcanic hazards. The chemistry of gases, which may separate from magma …

Earthquakes are known to precede volcanic activity, including long‐period or very long
period (VLP) volcanic seismicity. However, the relationships among earthquakes, VLP …

Abstract Long-period signal (LPs, 0.2–2 s) and very long-period signal (VLP, 2–100 s)
observed in the shallow volcanic plumbing system are typically repetitive and time-invariant …

The earth is a dynamic planet with abundant vibrating processes. Besides the earthquakes,
volcanoes and other activities, there is a special type of sources called persistent localized …

Earthquake magnitude (size) distribution is a major component required for seismic hazard
assessment and therefore, the accurate determination of its functional shape and variation is …
