Shield volcanoes: Hawai’i. (A) Shield volcanoes are built of layers of basaltic lava flows. There are no alternating layers of pyroclasts like those found in stratovolcanoes. (B) Mauna Kea, on Hawai’i, has a typical shield volcano profile. The island of Hawai’i, formed on a hot spot (see Section 12.4), is made up of five shield volcanoes that have joined together. Mauna Kea is the highest, standing at 4,207 m (13,803 ft).(B. © Peter French/Design Pics/Corbis)
