A seamount forms through volcanic activity, where magma rises from beneath the Earth's crust to create a mountain-like structure on the ocean floor. Over time, as the volcano becomes inactive and cools, it sinks below the ocean surface but remains as a seamount.
Muirfield Seamount was created in 1973.
Davidson Seamount was created in 1933.
Lōʻihi Seamount was created in 1940.
Buddha's Seamount was created in 2012.
A seamount is formed by volcanic activity beneath the ocean's surface, where magma rises and solidifies to create a mountain-like structure. Over time, the seamount can grow larger through continued volcanic eruptions or tectonic plate movement. As the seamount ages, it may eventually become extinct and eroded by ocean currents, forming a flat-topped seamount called a guyot.
Great Meteor Seamount was created in 1938.
Louisville seamount chain was created in 1972.
South Chamorro Seamount was created in 1977.
A sonar device can detect a seamount by sending out sound waves that bounce off the seamount and return to the device. By measuring the time it takes for the sound waves to travel to the seamount and back, the device can calculate the distance to the seamount and create a visual representation of its shape and size.
One possibility is Makarov Seamount at a height of 3,950m with a depth of 5,250m.
As the Meiji Seamount approaches the Asian Plate, it will encourage deterioration. It is estimated that the Seamount will be completely deteriorated within a few million years.
