A research has been done to understand the formation of islands.
Careerindia brings forth the various aspects of the creation of islands.
Here goes some of the interesting facts about the islands!
An undersea volcano in Tonga erupted in 2022 with a force greater than the largest US nuclear explosion of March 1954, making it one of the largest natural explosions in more than a century.
The mega-tsunami that struck Tonga's most populous island had waves up to 17 metres high on Tongatapu and up to 45 metres high along the shore of Tofua Island.
Researchers from the University of Miami in the US and the Khaled bin Sultan Living Oceans Foundation, a non-profit organisation established to promote ocean preservation, conservation, and restoration, were in charge of the study.
A tsunami simulation of the Tongan Archipelago was made for the study using field observations from the University of Auckland, New Zealand experts, before-and-after satellite film, drone imaging, and data from the Foundation.
According to the analysis' findings, which were reported in the journal Science Advances, the extremely shallow depth of the Pacific Ocean in the area served as a low-velocity wave trap.
The findings capture a tsunami that lasted for more than an hour and had waves as high as 85 metres one minute after the first explosion.
In 1883, the Hunga Tonga-Hunga Ha'apai, submarine underwater volcanic eruption occurred.
As a result of the Pacific and Indo-Australian tectonic plates colliding, a chain of islands formed.
The eruption provided as a great natural testing ground for theories and models that can be applied elsewhere to enhance disaster preparedness in the future.
It better comprehended previous eruptions and the ensuing tsunami as they are preserved in history and the geologic record.
