What is the highest speed lava has gone down a volcano?

Dear Reader,

The fastest moving flow I know of is from the 1977 eruption of Nyiragongo in Africa. I fissure developed on the flank of the volcano that drained the lava pond at the summit. Lava was moving about 40 mph (60km/hr) and at least 38 people died.
