Mauna Loa

Mauna Loa

. This radar image of the Mauna Loa volcano on the Big Island of Hawaii maps lava flows and other volcanic structures. Mauna Loa has erupted more than 35 times since the island was first visited by westerners in the early 1800s. The large summit crater, called Mokuaweoweo Caldera, is seen near the center of the image; this central depression was formed after lava flowed down the flanks of the volcano and magma was withdrawn inside it. If the height of the volcano is measured from its base on the ocean floor, Mauna Loa is the tallest mountain on Earth, rising almost 9 thousand meters above the ocean floor.
