Explore the 'dragon's territory' at the volcanic island of Hawaii

Indeed the world still has many beautiful wonders, just waiting for people to discover it.

Hawaii is a volcanic archipelago, where the mountains have never slept until today. For example, the great volcano Kilauea on the big island of Hawaii has flattened many homes in 2014 in lava tanks.

However, the same lines of lava - over hundreds of thousands of years - can contribute to forming one of the most beautiful heritage created by nature. That is the cave, or lava tube.

There are many types of lava tubes formed over time, but there are tubes that can be up to 15 meters wide, and up to kilometers long.

Those caves might have resorted to the word "art" to describe its beauty - nature's artistic masterpieces.

The origin of the lava tubes comes from the temperature difference . When the lava flows accumulate thick enough, the outer lava layer cools faster, turning it into a shell.

The origin of the lava tubes comes from the temperature difference.

The shell itself acts as an insulating layer, causing the lava inside to continue to melt, gradually forming a pipe. When lava flows into the sea, the only thing left is the lava tubes we are talking about here.

As we fumble in the cave from the sea, it means we are moving towards the cracks where lava escapes for the first time. And indeed, if this is called the cave created by dragons, many people may believe it.

Lava stone stalactites can form within hours.

Fumbling along the length of the pipe, they are indeed like caves by . dragons should dig.

In normal caves, you will see stalactites and stalagmites (stalactite and stalagmite) , which take about millennia to form. But lava stalactites can form in a few hours, just as thick and frozen lava drops are fast enough.

Occasionally, you will encounter "lava ponds" (of course, cold). It is formed when a large amount of lava concentrates on one point and then shrinks when it cools.

There are a lot of lava dungeon systems in the world like in Hawaii. For example, Jeju Island of Korea, with a system of Geomunoreum lava tubes longer than 8km. The cave is also very dark, cold and humid, but no less mysterious for visitors to explore.

As expected, the world still has many beautiful and extremely mysterious areas. It is important that you are brave enough to discover it or not.
