19034 Santorini           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Santorini is a Greek island in the Aegean Sea. The old name of the island is Thera. The 1950 eruption produced a small lava dome. About 1200 B.C. there was also a great eruption and its following tidal wave may have destroyed the Minoan culture of Crete.
