NASA showed the evolution of the youngest volcanic island on Earth

NASA showed the evolution of the youngest volcanic island on Earth
In 2014, in the Pacific Ocean, after the eruption of an underwater volcano, the island of Hunga Tonga-Hung Haapai appeared, which has not gone under water so far. 

The American space agency NASA filmed a video that shows the changes to which the youngest volcanic island is exposed on Earth.

It is noted that ashes from the eruption finally settled only in 2015, and scientists were able to see the island with a 120-meter high, located between the two older islands.

According to NASA scientists, now he can "live" from six to 30 years. The study, which gives an idea of ​​its longevity and erosion, allows us to understand some of the processes taking place on Mars, experts say.

Our interest is to calculate how the 3D landscape changes over time. This is the first step to understanding the rates and processes of erosion and deciphering why the island lasts longer than expected


- one of the authors of the study, Jim Garvin.


The largest changes in the shape of the island occurred in the first months after the eruption. So much of the once-oval island went under the water. NASA believes that these processes are similar to those that occur on Mars, and will help in its study. In particular, scientists hope, therefore, to find out whether there was ever an oceanic environment on Mars.

Previously, NASA told about the program of development of the Moon and Mars and about the joint work of Russia and the United States in the preparation of the flight to the moon.
