The Volcanic History

The Basal Volcanic Complex (ca. 160,000 to 100,000 years)
The Early Caldera Stratovolcano (ca. 100,000 to 30,000 years)
Lakki Pyroclastics and Avlaki Complex
Lacustrine and Pyroclastic Formations
The Melisseri - Evangelistra - Afionas Complex
The Emborios Complex
The Ellinika - Kyra - Lies Pyroclastic Complex
The Argos - Stavros Complex
The Main Caldera Formation (30,000 to 15,000 years ?)
The First Caldera Phase (?30,000 to 20,000 years ?)
The Second Caldera Phase (20,000 to <15,000 years ?)


The volcanic history of Nisyros Island can be divided into five major volcanic phases (Fig. 33). The given ages of the different phases are highly speculative due to sparse and contradictory age determinations.

Several methodologies are applied in a completely new way to achieve the necessary results.
