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).
By contrast, typical Pu`u `O`o `a`a (try saying that fast three times) flow advance rates were less than 1/3 mi/hr or 0.15 m/s. The fast `a`a flow on the night of February 1, 1996, advanced from near Pu`u `O`o over Pulama pali at a ripping 2/3 mi/hr, or 0.3 m/s. Pahoehoe flows are even slower than this.Now, lava can flow quite a bit faster than 6 mi/hr, but only in tubes or channels where it is confined and thermally insulated.Like most fluids, lava flows faster if it stays hot. For example, chocolate syrup that's just been in the refrigerator may not flow at all until it is warmed over the stove.ithin the current tube system, lava speeds have been measured up to 23 mi/hr, or 10 m/s. To put these speeds into perspective, let's compare them to typical human running speeds. Athletes can run the 100 yard dash in about 10 seconds, an average speed of 23 mi/hr or 10 m/s.
