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).
It has been recorded lava flowing at an excess 25 mph which is very fast for lava. It also depends on where the lava is being measured, for example if you were to measure how fast the lava is flowing at the front of the flow it's going to be very slow.bout 1 to 2 miles per hour with the fastest being about 5 miles per hour. Lahars, a mix of rock debris and water, flows very fast, usually around 60 miles per hour. Pyroclastic flow, a mix of hot gases, ash, and rocks that form a dense super heated current can reach speeds greater than 100 mph.
