Hidden crystals from volcanic rocks could predict volcanic eruptions

Volcanic rocks contain crystals formed when the magma moves from the depth towards the surface during volcanic eruptions. Recently, scientist studied the crystals using a new technique based on lasers. They discovered that these crystals contain growth layers similar to the growth rings from a tree. Interestingly, the layers represent a form of “memory” and understanding them may help predict volcanic eruptions. The crystals can record the changes occurring inside the volcano, before the eruption begins, thus providing a valuable warning signal.
