Several cameras, including a thermal one, are installed near the crater of Halemaumau located on the American island of Hawaii. The difficult to pronounce name has a very beautiful translation. The Hawaiian phrase Halemaʻumaʻu translates as “the house at the red fern.” The crater belongs to the Kilauea volcano and is part of the Hawaiian National Park.
Over the centuries, the shape of the crater has gradually changed. Today, it is an oval measuring about 800 by 900 meters. Because of its frequent activity, the depth of the crater is constantly changing. The lake of lava has a minimum depth, but it’s about 150 meters to the bottom of the crater from its top; when the crater is filled with lava, this depth becomes 30 meters.
The first descriptions of the crater date from the 19th century. A little later, in 1866, the famous American writer, Mark Twain, admired the natural beauty of the crater. At the beginning of the 20th century, an observatory was opened near the crater.
In recent years, Halemaumau has again attracted the attention of scientists and tourists from around the world. The crater has been active since 2008, and there are constant emissions of smoke and gas.
