Geomorphology
Although the fracturing process is not yet known, the altitudinal statistical analysis indicates that the caldera had formed just before the eruption. During this period the area of the island was smaller and the southern and eastern coastlines appeared regressed. During the eruption period the landscape was covered by the pumice sediments. In some places, the coastline vanished under thick tuff depositions, and in others recent coastlines were extended towards the sea. After the eruption, the geomorphology of the island was characterized by an intense erosional phase, during which the pumice was progressively removed from the higher altitudes towards the lower ones.
