June 1, 2000 - the 50th anniversary of Mauna Loa's
most spectacular eruption!
The 1950 eruption was the largest and most spectacular
historical eruption from the southwest rift zone of Mauna Loa.
It was especially noteworthy, for lava was erupted from a nearly
continuous 20-km-long fissure along the middle portion of
the rift. One of the significant things about this eruption
was that the flows reached the sea in less than four hours.
The eruption began on June 1, 1950. It followed the summit
eruption of 1949 by almost one year, consistent with the pattern
of flank eruptions succeeding summit eruptions within two years.
On the 50th anniversary of the eruption, this article summarizes
the high (and low) points of the eruption.
