Lower sea levels over the last 360,000 years are linked with more eruptions
When sea level drops far below the present-day level, the island volcano Santorini in Greece gets ready to rumble.
A comparison of the activity of the volcano, which is now partially collapsed, with sea levels over the last 360,000 years reveals that when the sea level dips more than 40 meters below the present-day level, it triggers a fit of eruptions. During times of higher sea level, the volcano is quiet, researchers report online August 2 in Nature Geoscience.
Other volcanoes around the globe are probably similarly influenced by sea levels, the researchers say. Most of the world’s volcanic systems are in or near oceans.
“It’s hard to see why a coastal or island volcano would not be affected by sea level,” says Iain Stewart, a geoscientist at the Royal Scientific Society of Jordan in Amman, who was not involved in the work. Accounting for these effects could make volcano hazard forecasting more accurate.
Santorini consists of a ring of islands surrounding the central tip of a volcano poking out of the Aegean Sea. The entire volcano used to be above water, but a violent eruption around 1600 B.C. caused the volcano to cave in partially, forming a lagoon. That particular eruption is famous for potentially dooming the Minoan civilization and inspiring the legend of the lost city of Atlantis (SN: 2/1/12).

It's simple if you know the rules.
That is one impressive place,, no telling when it may blow again.. but you can be assured ‘climate change’ will follow when it does.. for awhile anyway..
The Erf spins on locked in glide path with whatever takes a shot at it or shoots out of it.
Expeditions in the caldera have shown some interesting stuff lies within.. I’d go back just for the views.
Sea levels are not dropping around Santorini.
The island is rising.
Just like the land near Thermopylae.
It used to be next to the ocean but not anymore.
Total BS
“… when the sea level dips more than 40 meters below the present-day level, it triggers a fit of eruptions….”

Correlation is not necessarily causation. Unless a person is pushing an agenda.
I thought sea levels are rising?! But a drop of 40 meters? C'mon man!
We were supposed to go there, then COVID happened.
Since volcano induced globull warming is making the sea level rise, this should take care of itself in a few minutes, right?
I would like to spend the rest of my days sitting on that mountainside watching the sunset, eating bread w/ olive oil and drinking wine.
One can dream…
Better have lots of moo-lah.
Me too. Gotta have a dream.
I visited in ... 1982. Have wanted to go back ever since for another visit.
Perhaps the two events are related, but…..
“ Santorini’s magma chamber, which sits about four kilometers beneath the surface of the volcano. In the simulation, when the sea level dropped at least 40 meters below the present-day level, the crust above the magma chamber splintered. “”
So, the crust above the magma chamber, at 4000 meters is affected by a 40 meter drop in the water level. Maybe. Some have blamed earthquakes on dam reservoirs.
