Abstract Following a volcanic eruption which killed almost 2000 people in Cameroon in 1986, the Délégation aux Risques Majeurs, a French Government Agency, requested a report evaluating the risks of a similar eruption of CO2 in Auvergne: this volcanic province of the French "Massif Central" has structures comparable with those which were at the location of the Cameroon eruption. The lake Pavin, 90 m deep, located in a volcanic crater, is of meromictic type: the annual circulation of water is incomplete with the deep layer, (60-90 m), remains stagnant year to year. This property was confirmed by ten profiles of the content of 3H of the water column. A weak inflow of water (about 0.1m3.m2.yr') at the bottom of the lake plays an important role...
