The caldera would slowly refill with magma, building a new volcano, which erupted and then collapsed in an ongoing cyclical process.
This cataclysmic eruption was centered on a small island just north of the existing island of Nea Kameni in the centre of the then-existing caldera.

were responsible for NEEM project management, sample distribution, logistics support, and management.
It is also suggested that several months before the eruption, Santorini experienced one or more earthquakes, which damaged the local settlements.
Ice-core chemistry measurements were performed by J. The North Atlantic INTIMATE group of the INQUA Palaeoclimate Commission has previously recommended an Event Stratigraphy approach for the synchronisation of records of the Last Termination using the Greenland GRIP isotopic record as the regional stratotype and INTCAL98 for the calibration of radiocarbon dates [Lowe, J. Inter-regional correlation of palaeoclimatic records for the Last Glacial-Interglacial Transition: a protocol for improved precision recommended by the INTIMATE project group. Here, we present a revised protocol for time-stratigraphic correlation in the North Atlantic region over a more extended time period (30–8 ka).This employs the new NGRIP isotopic record and associated Greenland Ice Core Chronology 2005 (GICC05) as the regional stratotype, INTCAL04 for the calibration of radiocarbon dates, Bayesian-based statistical procedures for the construction of age models, and tephrochronology to validate correlations between regional site records.Volcanic eruptions contribute to climate variability, but quantifying these contributions has been limited by inconsistencies in the timing of atmospheric volcanic aerosol loading determined from ice cores and subsequent cooling from climate proxies such as tree rings. Here we resolve these inconsistencies and show that large eruptions in the tropics and high latitudes were primary drivers of interannual-to-decadal temperature variability in the Northern Hemisphere during the past 2,500 years.
