HCl degassing from extremely acidic crater lakes: preliminary results from experimental determinations and implications for geochemical monitoring. [PDF]
, 2016 Crater lakes are monitored to detect volcanic unrest starting from the assumption that they behave as condensers for magmatic gases. A further assumption is that acidic gases such as HCl are conservative once dissolved in water.

Toward a Magnitude Scale for Low Frequency Seismicity The LP energy for Campi Flegrei caldera [PDF]
, 2014 The energy released during a seismic crisis in volcanic areas is strictly related to the physical processes in the volcanic structure. In particular Long Period seismicity, that seems to be related to the oscillation of a fluid-filled crack (Chouet ...

Mercury in a geothermal and volcanic area in Patagonia, southern South America [PDF]
, 2019 Mercury and heavy metal contents are monitored using lichens as a tool for evaluation of air pollution. Lichens allow the identification of zones with anthropic impact, pollution hotspots and natural sources of contamination like volcanic emissions.

Geothermal systems in the Sunda volcanic island arc : Investigations on the islands of Java and Bali, Indonesia [PDF]
, 2015 The different physicochemical characteristics between volcano-hosted and fault-hosted on the Java island were determined. Boron isotope was applied to further distinguish the two geothermal systems.
