50th Anniversary of Mauna Loa’s Most Spectacular Eruption
The 1950 eruption was the largest and most spectacular eruption from the southwest rift zone of Mauna Loa since written records have been kept. It was especially noteworthy, for lava was erupted from a nearly continuous 20-km-long fissure along the middle portion of the rift zone.

One of the significant things about this eruption is that the flows reached the sea in less than four hours.

This is what we are really breathing… Mauna Loa..

This is above Pebble Beach Subdivision.. about half way down the mountain.

If it really flows… we could be in big trouble.. the airport is on a lava flow from it.. and it would block the roads.
and the gas (Vog) is really bad…

The island of Hawaii is divided into zones according to the degree of hazard from lava flows. Zone 1 is the area of the greatest hazard, Zone 9 of the least. To read more about a particular volcano or zone, click on the area of interest in the map or on the text links below.

Mauna Loa Eruption History

General Info

(This section is based upon data discussed by Walther Barnard of SUNY College of Fredonia and Frank Trusdell of HVO in separate papers within “Mauna Loa Revealed”, American Geophysical Union Monograph 92 (1995).)
Mauna Loa has erupted 39 times since 1832. These historical flows cover 806 km² of the volcano’s surface. Typically, these eruptions began in the summit caldera, Moku’aweoweo, with a curtain of fire (which is a 1 to 2 km line of lava fountains). Eruptions may consist solely of summit activity or they progress down- flank via rift zone dike propagation (in the subsurface) to feed flank vents. In the historic period, the Northeast Rift Zone has been the eruptive locus for 31% of the eruptions and covered 202 km² of land. The northwest quadrant has been the source of 6% of the eruptions (covering 130 km²), the Southwest Rift Zone has been the source for 25% of the eruptions (covering 233 km² of the land), and the summit region has been the site of 38% of the eruptions (many of the latter have remained in the summit caldera and thus covered little land, although others have spilled out into the norwest and northeast quandrants of the volcano).

The oldest Mauna Loa eruption in written history is said to have taken place in 1780. Testimony was taken from Keaweehu, a Hawaiian guide in the Wilkes party who occupied and mapped the summit from 1840 to 1841. It was said to have taken place not long after Captain Cook’s visit to the islands. In 1868, and an eruption from Mauna Loa caused the largest earthquake in Hawaii, registering as a magnitude 8 by modern methods. The lava flow of 1855-1856 is said to be one of the greatest flows ever seen by modern observers.
