Mauna Loa Volcano towers nearly 3,000 m above the much smaller Kilauea Volcano (caldera in left center). Hualalai Volcano is in upper right. In recent years Mauna Loa has not erupted with the frequency of Kilauea, but its 33 historical eruptions have, on average, generated much larger volumes of lava on a daily basis -- more than 10 times the lava output from Kilauea's current Pu`u`O`o eruption. Lava flows on Mauna Loa tend to travel much longer distances in a shorter period of time than those on Kilauea. Thus, warnings and notifications in the first few hours of an eruption are critical for public safety.
