A Volcano in the Alps?

Resumo

This paper analyzes the article published in Sankt-Peterburgskie Vedomosti (SPV) and a number of foreign studies addressing the natural cataclysm that occurred in Savoy (Western Alps) in 1751 and was recognized by witnesses as a volcanic eruption. This event was observed by V. Donati, a famous natural sc-ientist of the 18th century, and described by H.B. de Saussure, a prominent researcher of the Alps. Other evidence of similar phenomena in the Alps is presented from the historical data. It is suggested that a special type of explosive eruption, not accompanied by lava pouring out but still very dangerous may occur in the Alps.
