Machine Learning in Discriminating Active Volcanoes of the Hellenic Volcanic Arc [PDF]
Applied Sciences, 2021 Identifying the provenance of volcanic rocks can be essential for improving geological maps in the field of geology and providing a tool for the geochemical fingerprinting of ancient artifacts like millstones and anchors in the field of geoarchaeology ...

Geochemistry of CO2-Rich Gases Venting From Submarine Volcanism: The Case of Kolumbo (Hellenic Volcanic Arc, Greece) [PDF]
Frontiers in Earth Science, 2019 Studies of submarine hydrothermal systems in Mediterranean Sea are limited to the southern Italian volcanism, while are totally missing in the Aegean.

The Hydrothermal Vent Field at the Eastern Edge of the Hellenic Volcanic Arc: The Avyssos Caldera (Nisyros) [PDF]
Geosciences, 2021 Almost three-quarters of known volcanic activity on Earth occurs in underwater locations. The presence of active hydrothermal vent fields in such environments is a potential natural hazard for the environment, society, and economy. Despite its importance

Tomographic imaging of the NW edge of the Hellenic volcanic arc
Journal of Seismology, 2019 The broader South Aegean area is characterized by the convergence of the African and Eurasian lithospheric tectonic plates at a rate of approximately 30 mm/year, resulting in a complex and intense deformation of the Aegean (McClusky et al. Geophys. Res. 105: 5695–5719, 2000).

Seismicity in the Hellenic Volcanic Arc: relation between seismic parameters and the geophysical fields in the region [PDF]
Geophysical Journal International, 1994 SUMMARY A study of the spatial distribution of seismicity and seismic hazard and geophysical parameters is undertaken along the Hellenic Volcanic Arc (HVA). Seismicity of the area is divided in a cellular manner allowing analysis of the localized seismicity parameters and representation of their regional variation as contour maps.

Ore Geology Reviews, 2020 Abstract Hydrothermal mineralization processes are investigated along the Hellenic Volcanic Arc (HVA) and associated environments in order to describe the factors that control the spatial and time variability in the hydrothermal intensity and the composition of the mineral deposits formed.

Microseismic activity in the Hellenic Volcanic Arc, Greece, with emphasis on the seismotectonic setting of the Santorini–Amorgos zone [PDF]
Tectonophysics, 2006 Abstract The volcanic arc of the Hellenic subduction zone with its four volcanic centers is of major relevance when evaluating the seismovolcanic hazard for the Aegean region. We present results from a 22-station temporary seismic network (CYCNET) in the central Hellenic Volcanic Arc (HVA).

Journal of Volcanology and Geothermal Research, 2005 Abstract Geothermal activity in the Aegean island of Milos (Greece), associated with island-arc volcanism, is abundant both on-and off-shore. Hydrothermal fluids venting from several sites, mainly shallow submarine (up to 10 m), but also just above seawater level in one locality, were sampled over four summer field seasons.
