Where oceanic crust subducts beneath continental crust, belts of volcanoes known as continental arcs can form. Located around the world, these arcs may undergo episodic magma flare-ups—dramatic surges in the flow of magma into the continental crust at rates up to 20 times higher than normal. However, what triggers these extreme surges, which last tens of millions of years, can be unclear.

📋 Key Takeaway
The article discusses the geological phenomenon of magma surges in continental arcs, which are formed where oceanic crust subducts beneath continental crust. While this topic is primarily geological, it does not directly involve Iran or its political landscape. Understanding such geological processes can have implications for natural disaster preparedness in regions, including Iran, that may be affected by volcanic activity.
