A group of international scientists revealed that the heightened earthquake frequency
A group of international scientists revealed that the heightened earthquake frequency in Santorini at the dawn of 2025 was due to an enormous vertical magma column, the volume of which could have filled up a space equivalent to 20 large Giza Pyramids in Egypt.
The research team, which included a group of Greek scientists, published their findings in Science magazine and estimated that the magma column had penetrated over 20 kilometers inside the Earth’s crust.
The team estimates that the volume of magma involved was so large that it could fill nearly 200,000 Olympic-size swimming pools or amount to 200 times the volume of the Great Pyramid of Giza. They add that this quantity would be enough to cover Manhattan or the islands of Bermuda with a layer of magma about 9 meters thick.
The seismic swarm—marked by hundreds of noticeable earthquakes, some above magnitude 5—occurred within a very short time span. “It triggered a local state of emergency, school closures, and alarm among residents and visitors,” the researchers note. At the same time, there was uncertainty over whether the tremors were linked to volcanic activity or to the slipping of tectonic faults, similar to the one that caused
