caps the summits of Mauna Loa (center) and Mauna Kea (toward the top, center)
volcanoes on the island of Hawai`i. With its summit standing roughly 17 km
(56,000 feet) above its base and its flanks covering about half of the Island
of Hawai`i, Mauna Loa is the world?s largest volcano. According to the U.S.
Geological Survey, Mauna Loa?s peak rises roughly 4 km above sea level, its
flanks slope downward another 5 km to the ocean floor, and then it is so
massive it compresses the sea floor another 8 km!
Meanwhile,
toward the island?s southeastern shore, the ongoing eruption of Kilauea
continues. The red boxes indicate the location of the lava flow from the
volcano?s Pu`u `O`o cone, which has been erupting since 1983.
