In a new paper, the authors examined the frequency of supervolcano eruptions on the island of Santorini and the factors that could
About 3.6 thousandyears ago, a powerful explosion occurred here, as a result of which the central part of the island plunged into the sea. As a result, traces of more than 200 previous eruptions were exposed. Through their study, we found out the connection between the level of the Mediterranean Sea and the eruptions of Santorini.

Next, scientists studied in detail the consequences of 211eruptions of the volcano and found out that volcanic activity occurred when the water level in the Mediterranean was 40-80 m below modern. Only four eruptions of the supervolcano occurred when sea level was close to modern.
Geologists have modeled how the level changesThe world's oceans affect magma flows and it was determined that when the sea level was several tens of meters lower than the modern one, it was easier for molten rocks to move towards the Earth's surface.
This means that a decrease in the level of the world's seas can provoke volcanic eruptions: the authors believe that 60% of volcanic centers behave in this way.
