We review the state of knowledge on global volcanogenic Hg emissions to the atmosphere
and present new data from seven active volcanoes (Poás, Rincón de la Vieja, Turrialba …

The ability to mitigate and predict volcanic risk is a long-standing question in the
Geosciences' community, while the extent of volcanic activity may be regulated by a …

Volcanic gases have been monitored to predict eruptions since their compositions are
strongly affected by volcanic activities. Here, volcanic gas geochemistry is reviewed with the …

Fumaroles are a common manifestation of volcanic activity that are associated with large
emissions of gases into the atmosphere. These gases originate from the magma, and they …

In April 2015, an unpredicted rapid-onset eruption occurred at Calbuco Volcano, Southern
Andes of Chile. This event consisted of two, sub-Plinian eruptions separated by a few hours …

Current-day volcanic activity in the Azores archipelago is characterized by seismic events
and secondary manifestations of volcanism. Remote sensing techniques have been widely …

A field survey based on outcrop and hand-dug trench observations was conducted in the
Maruyamasawa-Fumarolic-Geothermal-Area (MFG) of the Zao Volcano. Powder X-ray …

Fumarolic fields, especially those with near-surface soil temperature< 100∘ C, are very
common features of active or quiescent volcanoes, with both open or closed conduits. Their …

Fumaroles are hydrothermal manifestations commonly associated with active volcanoes.
The dynamics of fumaroles are affected by interactions with internal and external factors …

Fumarole thermal monitoring is a useful tool in the evaluation of volcanic activity, since
temperatures strongly relate to the upward flux of magmatic volatiles. Once depurated from …
