Santorini

In a few months, Heidi and I will celebrate our 50th anniversary with a cruise to several Greek islands. We visited Greece on our 25th anniversary, too. One of the islands we visit, this time, is Santorini: Delightful! Then I learn one of the most massive volcanic eruptions happened (about 1600 B.C.) ... in Santorini !! Huh? It (probably) wiped out the Minoan civilization, is (perhaps) behind the stories of a lost Atlantis civilization, had a Volcanic Explosivity Index (VEI) of 7 and is still active. Huh? I reckon I gotta learn about this VEI stuff and when the next eruption might occur ... P.S. VEI is a measure of the amount & height of material ejected in an explosive eruption. Like the Richter scale for earthquakes, VEI=7 is 10 times greater than VEI=6. The Santorini eruption ejected some 100 km3 of material!
