Professor of Geophysics at the Aristotle University of Thessaloniki and president of the Institute for the Study and Monitoring of the Santorini Volcano (IMPIS), Kostas Papazachos, has analyzed possible scenarios of a tsunami caused by the underwater volcano Kolumbo, located about 6 kilometers northeast of Santorini.
The study, published in the Bulletin of Volcanology, uses simulations of marine gravity wave generation.
The results show that the ports and areas within the caldera of Santorini are relatively safe, with small waves of up to one meter. While the eastern and southeastern coasts, such as Monolithos, Kamari and Perissa, are more affected and could experience waves of up to 5 to 10 meters in the event of a total collapse of the Kolumbos caldera. The tsunami wave could reach the nearest coasts in just 2-3 minutes, and the most distant ones in 10 minutes.
Papazachos emphasizes that these scenarios do not indicate an immediate danger, but are important for preparing for an extreme event in the future. He suggests that residents and visitors know the safe places to which they can evacuate in the event of a tsunami warning.
"Santorini remains safe, but these studies help improve emergency plans and protect residents and visitors from a specific risk," the professor said.
