Though Panarea is the smallest island of the archipelago, in reality, if the entire volcanic structure were considered, its size would be quite respectable, and comparable with the larger Lipari.
The underwater part of Panarea has a maximum depth of 100 metres, and corresponds to the levelling by marine erosion when the sea was at a different level than it is now, and when the main structure of Panarea had already collapsed in several places.
