Geysers
A geyser is formed when Subterranean water from under the earth is heated by molten lava, and is forced out turbulently.
This whole area is in one of the most active volcanic regions in the world. The water in underground caves is pressurised by the intense heat and forced out through the pipe.
Stunning photos! it looks like a different world ...
Is it dangerous to get close to the geysers? The combination with the steel blue sky is breathtaking! Very well done :-)
