The belt follows the coasts of South America.
Know how underwater volcanoes are formed in this ScienceStruck write-up. Shield volcanoes are formed by lava flows of low viscosity - lava that flows easily. The width of a shield volcano is usually 20 times its height on average but that doesnt mean that they do not reach high altitudes.

It is the newest volcano created by the Hawaiʻi hotspot in the extensive HawaiianEmperor seamount chain. Mauna Loa the largest of the shield volcanoes is 13677 feet above sea level which means it rises over 28000 feet above the deep ocean floor and would be the worlds tallest mountain if much of it were not underwater.
A shield volcano is a wide volcano with shallowly-sloping sides. 9102005 Submarine volcanoes are underwater vents or fissures in the Earths surface from which magma can erupt. This underwater volcano may seem novel but it is by no means new for its formation started approximately 400000 years in the past.
3182019 The Sierra Negra located at the southeastern end of Isabela Island is classified as a shield volcano and can be found in the Galapagos Islands which is an area that owes its very existence to volcanic activity. A shield volcano is usually built up from highly fluid magma flows which results in a volcano with a low profile that is spread over a large area similar to the shield of a warrior if it were lying on the ground.
