The Methana Volcano is Still Active
Introduction
Scientists studied the Methana volcano in Greece. It is near Athens. The volcano did not erupt for 100,000 years. But it is not dead. There is still hot rock under the ground.
Main Body
Scientists looked at 1,250 small crystals. These crystals tell the history of the volcano. The scientists found that hot rock, called magma, is always there. There is a lot of water in the magma. This water comes from the ocean floor. The water helps make more magma. The magma turns into hard rock quickly. Because of this, the volcano does not erupt often. But the magma still grows under the ground. This means the volcano is not dead. It is just waiting.
Conclusion
A quiet volcano is not always a dead volcano. It can still be dangerous. Scientists must watch these volcanoes more carefully now.
