Description:
Volcanic activity on the island of Ischia included both effusive and explosive eruptions,
mainly occurred in the eastern sector of the island. Vent location, eruption dynamics,
transport mechanisms and depositional processes, have been reconstructed for each
recognized unit. In the past 10 ka, periods of quiescence alternated with periods of very
intense volcanism, which was mainly concentrated at about 5.5 and over the past 2.9 ka.
Volcanism was not continuous and strongly influenced by the mechanism of a resurgence
phenomenon, which affects the island since about 33 ka. Therefore, it has been hypothesized
that magma intrusion and uplift events occurred intermittently. In the past 5.5 ka, volcanic
activity has been invariably accompanied by the emplacement of slope instability-related
deposits testifying that also slope instability was induced by reactivation of vertical
movements, likely related to resurgence.
