TLDR
In this paper, the authors have shown that there is a considerable inflow of gas into both crater lakes of Monticchio, Southern Italy, which are located in two maars that formed 140, 000 years ago during Mt. Vulture volcano last eruptive activity.Abstract:
Geochemical investigations have shown that there is a considerable inflow of gas into both crater lakes of Monticchio, Southern Italy. These lakes are located in two maars that formed 140 000 years ago during Mt. Vulture volcanos last eruptive activity. Isotopic analyses suggest that CO2 and helium are of magmatic origin; the latter displays 3 He ⁄ 4 He isotope ratios similar to those measured in olivines of the maar ejecta. In spite of the fact that the amount of dissolved gases in the water is less than that found in Lake Nyos (Cameroon), both the results obtained and the historical reports studied indicate that these crater lakes could be highly hazardous sites, even though they are located in a region currently considered inactive. This could be of special significance in very popular tourist areas such as the Monticchio lakes, which are visited by about 30 000 people throughout the summer, for the most part on Sundays.read more

Lakes Nyos and Monoun Gas Disasters (Cameroon)—Limnic Eruptions Caused by Excessive Accumulation of Magmatic CO 2 in Crater Lakes
TL;DR: In this article, a review paper on the lakes Nyos and Monoun gas disasters in Cameroon, and their related geochemistry is presented, which describes the unusual geochemical characters of the lakes, i.e., strong stratification with high concentrations of dissolved CO2; the evolution of the CO2 content in the lakes during preand syn-degassing; the noble gas signatures and their implications; a review of models of a limnic eruption; a revision of a spontaneous eruption hypothesis that explains the cyclic nature of a Limnic eruption.

Active degassing of mantle-derived fluid: A geochemical study along the Vulture line, southern Apennines (Italy)
TL;DR: In this paper, a geochemical study of gas emissions along a NE-SW transect in southern Italy was conducted to test the hypothesis that the region around Monte Vulture is affected by degassing of mantle-derived fluids through a lithospheric discontinuity.

Multidisciplinary characterisation of sedimentary processes in a recent maar lake (Lake Pavin, French Massif Central) and implication for natural hazards
Emmanuel Chapron,Patrick Albéric,Didier Jézéquel,Willem Versteeg,Jean-Louis Bourdier,J. Sitbon +5 more
TL;DR: In this paper, the most recent maar lake of the French Massif Central (Lake Pavin) is documented for the first time based on high resolution seismic reflection and multibeam bathymetric surveys and by piston coring and radiocarbon dating on a sediment depocentre developed on a narrow sub aquatic plateau.
