  Mauna Loa - Wikipedia, the free encyclopedia
Mauna Loa is an active shield volcano in the Hawaiian Islands, one of five volcanoes that form the Island of Hawaii.
Mauna Loa is a shield volcano, meaning that its slopes are shallow because its lava is extremely fluid (it has low viscosity).
Mauna Loa is a Decade Volcano, which means it has been identified as worthy of particular research in light of its frequent eruptions and proximity to populated areas.

Mauna Loa erupts less frequently than does Kilauea, but it tends to produce a much greater volume of lava over a shorter period of time.
Nearly all of the Mauna Loa eruptions observed since the early 1800's began at its summit caldera; during half of these, the activity subsequently shifted to either the northeast or the southwest rift zone.
Two areas on Mauna Loa are classed as Zone 6 because they are currently protected from lava flows by the local topography.

 Hawaii's Mauna Loa volcano is beginning to stir, new data reveal :10/02
Mauna Loa ­ Hawaii's biggest and potentially most destructive volcano ­ is showing signs of life again nearly two decades after its last eruption.
Recent geophysical data collected on the surface of the 13,500-foot volcano revealed that Mauna Loa's summit caldera has begun to swell and stretch at a rate of 2 to 2.5 inches a year, according to scientists from the U.S. Geological Survey (USGS) and Stanford University.
"Mauna Loa is capable of erupting huge volumes of lava in a relatively short period of time, and the flows can reach great distances," Segall observed.

 Hazards of Mauna Loa
Mauna Loa has a summit caldera and two rift zones, one extending northeast from the caldera and the other to the southwest.
Since more eruptions are inevitable on the flanks of Mauna Loa, the U.S. Geological Survey's Hawaiian Volcano Observatory (HVO), as a public service organization, has an obligation to increase the public's awareness of the hazards posed by future eruptions and to improve the designation of hazard zones as more information becomes available.

 AGU Web Site: Mauna Loa in Technicolor   (Site not responding. Last check: 2007-10-22)
Mauna Loa was exceptionally active in the middle of the 19th century (1843—1887) at a time when its more diminutive sibling, Kilauea volcano (to the right of Mauna Loa in the figure above), was attracting visitors to Hawaii.
Consequently, Mauna Loa eruptions tend to be much larger, resulting in extensive lava flow fields that cover the volcano's surface at a rate of 40% every 1000 years with flows that travel many kilometers from the vents; five have reached the coast since 1868.
For these reasons, Mauna Loa was chosen along with 14 other volcanoes for special study as part of the Decade Volcano Project by the International Association of Volcanology and Chemistry of the Earth's Interior.
