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).
Rhyolitic Lava. Rhyolitic lava has the highest viscosity of any type of lava, and it has the greatest content of SiO 2. Typically, the SiO 2 content of rhyolitic lava is greater than 68 percent of its total composition. It flows much slower than andesitic and basaltic lava.t has a high iron and magnesium content. It has a relatively low viscosity, when compared to other types of lava. It is the fastest flowing lava. Basaltic lava is commonly expelled from shield volcanoes, and it usually flows in the Pahoehoe or A'a style.
