An intense reaction occurs after water is injected into molten rock.

Not content with just watching the stuff explode out of volcanoes, researchers at the University at Buffalo have created their own lava -- just to watch it explode.

Research - Nov - JGR - Solid - Earth

The research, published Nov. 10 in JGR Solid Earth, details a set of experiments the team conducted to understand how volcanoes, full of magma, naturally interact with water. Sometimes when the two forces collide nothing happens at all, but other times, you get a fantastic magma-water explosion. The research team wanted to work out why that might happen.

To learn more about this strange interaction, which is termed "phreatomagmatic eruptions" in natural volcanoes, the team built furnaces and filled them with rocks, heating the materials up to around 2,400 degrees Fahrenheit. Once the rock had melted, they'd pour it into a steel box and then inject it with jets of water.

Hope - Explosion

And then they'd wait -- and hope for an explosion.

The results speak for themselves:

Interactions - Activity - Times - Water - Eruption

Sometimes, the lava-water interactions would provide intense explosive activity and other times the water would mostly evaporate without generating any huge volcano-like eruption. On...
