Phreatic and hydrothermal eruptions are small energetic explosive events that generally
have few to no precursors and represent a considerable hazard in tourist and urban areas …

Carbon dioxide is one of the most important gasses naturally released from geothermal
systems. Establishing the processes and pathways that regulate the CO 2 diffuse degassing …

Degradation mechanisms affecting non-methane volatile organic compounds (VOCs) during
gas uprising from different hypogenic sources to the surface were investigated through …

The actively extending axial zone of the southern Apennine mountain belt of Italy is
characterized by a substantial flow of non-volcanic gas to the surface. In this study, we have …

We present the results of a detailed bathymetric survey of Pozzuoli Bay (Gulf of Naples,
Italy). This shallow marine area, along with the Campi Flegrei inland, is a highly active …

Volcanic CO2 emissions play a key role in the geological carbon cycle and monitoring of
volcanic CO2 fluxes helps to forecast eruptions. The quantification of CO2 fluxes is …

Cerro Pabellón is a hidden high-enthalpy geothermal system (reservoir temperature up to
250° C) located in the Pampa Apacheta (northern Chile), where the first geothermal power …

Ciomadul is the youngest volcano in the Carpathian‐Pannonian Region, Eastern‐Central
Europe, which last erupted 30 ka. This volcano is considered to be inactive, however …

The chemical composition of volatile organic compounds (VOCs) in soil gases from the
Solfatara crater (Campi Flegrei, Italy) was analyzed to investigate the effects of …

Surface geothermal expressions such as mud pools, fumaroles, mineral deposits, collapse
pits, and hydrothermal eruption craters vary in scale and type over space and time. The …
