Liquid Fireworks

The geyser creates spectacular displays of superheated water and steam

This capture shows Strokkur at the peak of its eruption, where superheated water at 100°C (212°F) explodes upward in a magnificent display of geothermal power. The eruption process begins when surface water seeps down through cracks in the rock, encounters magma-heated rock at depth, and rapidly expands into steam. The pressure buildup eventually overcomes the weight of the water column above, creating these spectacular liquid fireworks that have amazed visitors for over 1,000 years.
