The Hawaiian–Emperor seamount chain is a mostly undersea mountain range in the Pacific Ocean that reaches above sea level in Hawaii. It is composed of the Hawaiian ridge, consisting of the islands of the Hawaiian chain northwest to Kure Atoll, and the Emperor Seamounts: together they form a vast underwater mountain region of islands and ...
The Hawaiian Emperor seamount chain is a well-known example of a large seamount and island chain created by hot-spot volcanism. Each island or submerged seamount in the chain is successively older toward the northwest.
The physical mechanism causing the unique, sharp bend in the Hawaiian-Emperor seamount chain has been uncovered in a collaboration between the University of Sydney and the California Institute of Technology (Caltech).
The Hawaiian-Emperor Chain is one of the most spectacular geological features on Earth, stretching nearly 6,000 km from the active submarine volcano Lō’ihi near Hawaii to the Detroit (81–75...
This study would involve seagoing expeditions to obtain critical information about the volume and composition of new crust formed from hot spot magmatism, how it varies along the island chain, and how the tectonic plate deforms in response to the weight of the volcanoes.
These volcanic peaks rising above the ocean surface represent only the tiny, visible part of an immense submarine ridge, the Hawaiian Ridge—Emperor Seamount Chain, composed of more than 80 large volcanoes. Mauna Kea Volcano on the island of Hawaii has an altitude of 13,796 feet.
FULL STORY. The volcanic islands of Hawaii represent the youngest end of a 80 million years old and roughly 6,000 kilometres long mountain chain on the ground of the Pacific Ocean. The so-called...
The physical mechanism causing the unique, sharp bend in the Hawaiian-Emperor seamount chain has been uncovered in a collaboration between the University of Sydney and the California Institute of Technology (Caltech).
The new ages for the Hawaiian-Emperor bend and seamount chain help to clarify the connections among mantle dynamics, Pacific plate motion, and major reorganizations of plate boundaries in the western Pacific Ocean.
The Hawaiian–Emperor seamount chain is a series of volcanoes and seamounts extending about 6,200 km (3,900 mi) across the Pacific Ocean. [n 1] The chain was produced by the movement of the ocean crust over the Hawaiʻi hotspot, an upwelling of hot rock from the Earth's mantle.
