Volcanic Eruptions may be Easier to predict once Magma cools down: Research

A new research suggests that volcanic eruptions could be easier to forecast once the magma cools down. The research team reached the conclusion after studying crystals.

Information was gathered from the two eruptions that occurred in Mount Hood. The first eruption occurred 1,500 years back and the second one erupted 200 years before the present time. With every occurrence of the volcano, crystals were formed, which provide insight into a history of the events causing the eruptions and the temperature at that time.

One finding reveals that crystals were trapped in cool lava and were full of minerals. The study also reveals that the magma is too cool to cause the eruption and might have continued to exist in the same state for 100,000 years prior to the first eruption.

Reservoir of molten rock in Mount Hood lies approximately three miles underground. The average temperature is 1,380 degrees Fahrenheit, which is very cool to kick off a volcanic eruption.

Researchers consider that if this temperature is increased a little i. e. by 200 degrees Fahrenheit, an eruption could occur. Kari Cooper, professor of geology at the University of California states the above findings prove that eruption cannot take place as magma is not that hot to initiate it. She added, "That means that having a magma that can erupt is a special condition. Our expectation is that there are a lot of volcanoes that behave this way".

Mount Hood took its shape when one continental plate was pressing into and under a second plate in a subduction zone. When the crust is pushed into the ground, it heats and melts rocks, thereby leading to eruption of volcano.
