"Archeological reports that I have encountered several times indicate there was earthquake/volcanic disturbance of a less serious nature than the final cataclysm, which nevertheless was sufficient to encourage the populace of Santorini/Thera to move away before the big one, and occurred about 20 years earlier."I've never heard of that (other than in your posts). The island was apparently abandoned prior to an eruption, as no human remains were found, and (if true) that's likely to have been the result of rumbling and steam and gases in the caldera (which is prehistoric, formed 22,000 years ago, not in the13th, 14th, 15th, 16th, or 17th c BC). In Italy, the Bay of Naples, there was a severe earthquake 17 years prior to the eruption of Vesuvius, the repairs for which were still going on when the famous eruption took place in 79 AD, so perhaps you're thinking of that.
Addenda and Corrections to "The Exodus Chronicles"Recently, in relation to his ongoing excavation at Tell el Daba, which he believes to be the site of ancient Avaris, Manfred Bietak has rescinded his former assertion that the stratum in which Minoan artifacts, decorations and volcanic pumice were discovered belongs to the time of the pharaoh, Ahmose I. Bietak now concludes this stratum can be assigned to the reign of Thutmose III, instead. Bietak also dates the eruption of Thera to ca. 1500 BCE, in light of his new theory, and takes issue with those who place the cataclysmic event to about 130 years earlier. In brief, Bietak now wishes to eliminate any chronological problems connected with his newer theory. Even if he is correct and there was no volcanic blast in the Aegean at the time of King Ahmose, there still remains the unaccountably bad weather and flooding during his reign, as recorded by himself.

And then there is the interesting premise of the Thera volcano devastation while a "Tethmosis" was pharaoh, two disasters having then occurred within a half century--or less.Helmi, EzbetFormerly called Tell el-Qirqafa. Amsterdam University survey of 1984 noted the presence of a quartzite block in the village, measuring 100 x (75+) x 17cm, pierced by a central square shaft. This site was probably the location of the Djadu of the 12th dynasty, found by Labib Habachi. Now the site is the focus of a major excavation by the Austrian Institute, working under cultivated fields some 800 metres west of their excavations at Tell ed-Daba. Major discoveries include Minoan wall paintings, an Eighteenth Dynasty palace, a Hyksos palace and water-supply system.
"The eruption took place long after Herodotus wrote about the island."
Actually, concerning the date proposed for the eruption as 1628 BC +-, and the life of Herodotus being 450 BC +-, this would mean that the eruption took place long BEFORE Herodotus wrote about the island. In fact almost 1,200 years before, which means Herodotus might not even have been aware of the event it was so much earlier than his time. There is much interesting information, photos and artwork shown at serches for Akrotiri/Santorini/Thera, that covers some of the controversy, as well as the many beautiful traces that were buried by the earthquake, and later eruption.
