I read an interesting analysis on the impact of Thera on the demise of the Minoan civilization.
According to this theory, the initial eruption would have caused a significant tsunami (there was a recent PBS story on research on Crete showing significant tsunami damage at the right age). This would have destroyed the port area, as well as killing many of the skilled workers who would have been near the shipyards. The ships at sea would have been able to survive and make it home OK, but there would have been few skilled workers to maintain them and build replacements for any lost, or as they deteriorated. Thus after about a hundred years, the Minoans would no longer have been the major seapower as their ships rotted away, and the Myceneans would have been able to successfully conquer them.
AFAIC, it’s not new research, it’s just another part of the supereruption mythos. The supposed tsunami knocked down a single house. There’s no sign of rapid decline in Minoan sites, just everything going along as if nothing is wrong, then the Minoan sites were sacked by the Mycenaean Greeks. Where the Minoans had been running trade routes, the Mycenaeans took over. This is (at best) difficult to explain with a caldera collapse-induced tsunami, as the side that’s gone points right toward the Greek mainland and most of the major Mycenaean ports. :’)
