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).
They are not speedy-even the fastest Hawaiian lava flows of the last century would not have aroused the interest of those speed-cam operators lurking in parked vans. In the 2000 years or so that people have been around to observe lava flows, few were well timed until the 1950 Mauna Loa eruption.This is a small data set-the only one that we have to estimate future potential lava flow speeds.he good news is that there are some ways to determine lava flow velocities from these older flows. While advancing across the ground, lava flows can run up onto pre-existing features like cinder cones. The faster the flows advance, the larger the amount of run up.
