The eruption of the volcano in Tonga did not only affect the surrounding areas, but apparently the shock wave reached as far as Greece. Professor of Natural Disasters at the Technical University of Crete, Costas Synolakis, speaking at the First Program, pointed out the similarities between this explosion and that of Santorini, which destroyed the Minoan civilization.
“The eruption of the volcano in the Tonga Islands is a geophysical interesting natural phenomenon that does not happen often. The waves reached not only Peru but the west coast of Africa, while all the earth’s oceans felt the explosion. “The reason we are interested in Greece is because that is how the explosion of Santorini was,” he stressed.
“A powerful submarine eruption had taken place in 1883 on the Krakatoa volcano in Indonesia, when the waves were actually felt as far as the London Observatory,” said Mr. Synolakis, referring to the Minoan eruption in Santorini 3500 years ago. of the 10 largest explosions ever in history.
According to the first calculations for the explosion in Tonga, it turns out that the explosion in Thira was 100 times stronger. “So we are interested in understanding what has happened since the eruption of the Tonga volcano, because that way we will better explain the impact of the Santorini volcano and we will understand what happened, how the Minoan civilization disappeared, what happened next,” he said.
As for the underwater volcanoes, the volcano of Santorini has one of the largest craters in the world, noted Mr. Synolakis. “Santorini makes small explosions every 50-70 years and makes big explosions, like the Minoan eruption every tens of thousands of years, some say every 16,000 years. “For a big explosion to happen soon, looking at what has happened historically in the past, the probability is very small”, explained Mr. Synolakis.
Finally, he mentioned that in our country there are many active volcanoes and there are always geophysical phenomena that can surprise us, however he noted that “the good thing about volcanoes is that before they make a big eruption they start long before they make seismic vibrations and give different signs in order to prepare. “It’s very rare for a volcano to erupt without giving any warning at all, in fact the warning signs can last for up to several months.”
