In Hawaii the fastest flows we've recorded were those of the 1950 Mauna Loa eruption. These were going about 6 miles (10 kilometers) per hour through thick forest. That was the velocity of the flow front.nce the lava flows became established and good channels developed, the lava in the channels was going at more like 60 km/hour! On January 10,1977, a lava lake at Nyiragongo drained in less than one hour. The lava erupted from fissures on the flank of the volcano and moved at speeds up to 40 miles per hour (60 km/hr).
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.ypically, 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.
