Berlin, April 4 : A new research has suggested that a sharp bend in the middle of the Hawaii `necklace' of islands is a result of a rapid drift of the region's `hotspot' in a southward direction between 80 and 40 million years ago before it came to a complete halt.
More than 80 undersea volcanoes and a multitude of islands are dotted along the Hawaii-Emperor seamount chain like pearls on a necklace.
A sharp bend in the middle is the only blemish.
This characteristic bend in the trail of the 5000-kilometer long Hawaii-Emperor seamount chain is one of the most striking topographical features of the earth, and is an identifying feature in representations of the Pacific Ocean floor.
