This list is based mainly on the remarkable 1631-1944 eruption log compiled by Scandone et al. Vigorous tephra emission continues for about a week, and much destruction is caused by the fall of pyroclastics, mainly in Ottaviano, Somma and other villages in the N to NE sector of the volcano. Vigorous tephra emission follows, causing total destruction in Somma, Ottaviano and S. Anastasia.
Lahars occur during and after the eruption.
This is one of the most devastating eruptions of the 1631-1944 cycle, with about 400 casualties. Since early April 1944, Vesuvio has remained in a state of repose, the longest repose period since the one ending in 1631.
