Santorini on alert for absorption: activity has been detected in the Colombo underwater volcano - voila! news

The last time Colombo erupted in 1650, 70 people were killed. The increase in population and tourism on the nearby island of Santorini raises concerns about the effects of a similar outbreak today, which would be far more deadly.


It was dormant for 400 years, but now Kolumbo, an underwater volcano near the Greek island of Santorini, has awakened.

A previously undetected magma chamber is gradually filling with volcanic fluid, leading scientists to recommend real-time monitoring of the volcano.



The last time Colombo erupted, in 1650, 70 people were killed.

Now, the increase in population and tourism in Santorini is raising concerns about the effects of a similar outbreak today, which would be much more deadly.

Colombo belongs to a family of extremely explosive active volcanoes, capable of producing an eruption column tens of kilometers high. It can also trigger a tsunami.

Using new imaging techniques - similar to ultrasound - scientists from Imperial College London identified the magma chamber filling up about three kilometers below the volcano.

From the conclusions published in the journal Geochemistry, Geophysics, Geosystems, it appears that although the eruption is not immediate, the volcano poses a serious danger.



Another group of researchers from the Joides Resolution Institute are drilling into the sediments around Colombo to reconstruct its eruptive history over the past few million years.

They also hope to understand the links between earthquakes and volcanoes in the region and study the effect of sea level change on the intensity and frequency of eruptions.
