Greeks need not lose any sleep over having to face the destructive might of a tsunami, at least not in the next 50 years, according to research made public yesterday.

The Institute for Geological and Mineral Exploration (IGME) presented a survey carried out in cooperation with the Athens Observatory’s Geodynamic Institute between 1992 and 1995, pinpointing two potential trouble zones — the Amorgos area in the Cyclades and the Bay of Argos in the northeastern Peloponnese.

Scientists concluded that major landslides that could trigger a tsunami should only be expected near Amorgos every 100 years, and twice in a millennium off Argos. As the last tsunami that started near Amorgos was in July 1956 — reaching some 20 meters in height — IGME officials said yesterday that the next one ought not to occur for another half-century.
