Santorini GPS Station (1 of 3) (IMAGE) Georgia Institute of Technology Caption Georgia Tech associate professor Andrew Newman has positioned more than 20 GPS stations on Santorini. Some have moved as much as 9 cm since the caldera reawakened in January 2011. Should the volcano erupt underwater, it could produce local tsunamis, which could be dangerous for cruise ships that commonly visit the tourist attraction.
