  1. After watching a PBS documentary on the incredible Tonga blast, they indicated Kolumbo could be among thousands of submarine volcanoes which could erupt explosively. I’ve been to beautiful Santorini, having married a Greek girl, and I’ve always been interested in volcanology and seismology along with meteorology. I’d hate to see anything bad happen in Santorini… such a beautiful place. We also went to the nearby island of Milos a couple of times, which is also an ancient volcanic island and very beautiful.
