Mauna Loa is Hawaiian for “Long Mountain”, probably because of its long, gently sloping shape. Mauna Loa is a single mountain on the island of Hawaii. The island of Hawaii is actually an island made up of five volcanoes which “blend” together because of their closeness to each other, making a single island.

The massive Haleakala shield volcano forms the eastern portion of the dumbbell-shaped island of Maui. The summit of 3055-m Haleakala contains a dramatic, 3.5 x 9.5 km summit crater that is widely breached on the north and SE sides. The “crater” is not of volcanic origin, but formed as a result of the coalescence of headward erosion of the Koolau and Kaupo valleys. Subsequently the crater has been partially filled by a chain of young cinder cones and lava flows erupted along a major rift zone that extends across the basaltic shield volcano from the SW to the east flanks. Another less prominent rift zone trends north from the summit. The most recent eruption of Haleakala was thought to have occurred between the exploring voyages of La Perouse in 1786 and Vancouver in 1793, but uncertainty surrounds the date of this event, which could have occurred in about 1750 AD (anthropological evidence) or several centuries earlier (radiocarbon dates).

Kilauea volcano, which overlaps the east flank of the massive Mauna Loa shield volcano, has been Hawaii’s most active volcano during historical time. Eruptions of Kilauea are prominent in Polynesian legends; written documentation extending back to only 1820 records frequent summit and flank lava flow eruptions that were interspersed with periods of long-term lava lake activity that lasted until 1924 at Halemaumau crater, within the summit caldera. The 3 x 5 km caldera was formed in several stages about 1500 years ago and during the 18th century; eruptions have also originated from the lengthy East and SW rift zones, which extend to the sea on both sides of the volcano. About 90% of the surface of the basaltic shield volcano is formed of lava flows less than about 1100 years old; 70% of the volcano’s surface is younger than 600 years. A long-term eruption from the East rift zone that began in 1983 has produced lava flows covering more than 100 sq km, destroying nearly 200 houses and adding new coastline to the island.
