Hotspot volcanoes

More volcanoes found around Santorini, but they are inactive | archives, greece, history & science


ATHENS – After American and Greek researchers warned in early 2021 that Santorini, home to a now dormant volcano that erupted 3,666 years ago, could explode again, researchers have discovered other inactive volcanoes around the island.

A seismic study of the seabed, using sound waves, revealed the discovery buried under volcanic eruption deposits to the west of the island and scientists also revealed for the first time how Santorini and its Neighboring volcanoes, Kolumbo and Christiana, were created and have evolved over time. .

The results were published a few in the scientific journal Geology. The research was led by Jonas Preine, from the Institute of Geophysics at the University of Hamburg, said Kathimerini. Participants also included Associate Professor from the University of Athens Evi Nomikou and Professor Emeritus Dimitris Papanikolaou, as well as researchers from the Helmholtz Center for Ocean Research Kiel and University of Clermont Auvergne.

In March of this year, the US-Greece team of scientists working to create a geomorphological map of Santorini’s tourist hotspot to “improve hazard assessments” said it was “at high risk of volcanic hazards. and seismic ”.

The scientists, whose article on the subject was published in the Journal of Maps, applied planetary geological mapping methods to underwater data to create an onshore-offshore geomorphological map of the Christiana-Santorini-Kolumbo volcanic group, according to the article.

“Underwater geomorphological maps are used to provide geological context and spatial information on landforms and associated geohazards for risk management,” their summary reads.

The long dormant submerged volcano called Caldera on the Nea Kameni islet opposite the main island of Santorini is one of the main attractions and tourists can walk to the top.

In 2012, the Volcano Discovery site stated that “there are (still minor) signs that the Santorini volcano could wake up in the average future (months to years). Predicting IF and if so, WHEN exactly there will be an eruption again is impossible – volcanoes are and always will be unpredictable.

“It is quite certain, however, that the volcano will erupt again in the future, as it is an active volcano and far from extinct,” the report added, with the volcano having erupted nine times. in 2000 years, the last in 1950.
