Mokuaweoweo caldera is at the summit of Mauna Loa Volcano. The caldera is 2.7 miles long by 1.6 miles wide (4.3 by 2.5 km). This photo is a view across Mokuaweoweo Caldera looking to the north. Immediately north and south of the caldera are pit cra
ters, appropriately named North Pit and South Pit.
Mokuaweoweo Caldera can also be seen from space. The Island of Hawaii is
made up of five volcanoes:
Mauna Loa, and
Kilauea. This space shuttle photograph shows the
characteristic features of each volcano. On the north flank of Kohala Volcano, just to the west (right) of the clouds, lies
deeply eroded Pololu Valley. Light colored glacial deposits cap the summit of Mauna Kea Volcano. The 1800-1801 lava flows
are clearly visible on the northeast rift of Hualalai Volcano. Historical lava flows drape the northeast and southwest rift
zones of Mauna Loa Volcano. Most of Kilauea Volcano is obscured by clouds, except for the southwest rift zone. Courtesy of

This color infrared space shuttle photograph shows Mauna Loa and Kilauea Volcanoes. Mauna Loa's Mokuaweoweo Caldera is to the left of center. The northeast and southwest rift zones are the source of the historical lava flows. Hilo Bay is at the top
right. The summit of Kilauea is obscured by clouds. Historical lava flows of its southwest rift zone are just below the center. Aa lava flows from the early episodes of the Puu Oo eruption are visible near the right center. Notice the small plume fro
m the on-going eruption. Courtesy of NASA and the Hawaii Space Grant College, University of Hawaii.
