How Does Lava Pours Steadily From Hawaii's Kilauea Volcano | WSJ Work?

Lava flows from Hawaii’s Kilauea volcano like water pouring from a tap, but much hotter and slower.

Imagine you have a big pot of soup on the stove. The heat makes it bubble and move, and if you open the lid just a little, some soup starts to pour out slowly. That's kind of what happens with lava inside Kilauea, a volcano in Hawaii. Deep under the ground, there’s molten rock, called magma, that gets really hot, like 1,000 degrees! When the pressure builds up, it finds a way out through cracks or holes in the Earth's surface.

Think of the magma as a river underground. It moves slowly but constantly. When it reaches the surface, it becomes lava and starts to flow, like syrup coming from a bottle. Sometimes the lava is thick and moves slowly, other times it’s more runny and goes faster.

This steady pouring is why people can watch lava flows for hours, they're like nature's own slow-motion show! Lava flows from Hawaii’s Kilauea volcano like water pouring from a tap, but much hotter and slower.
