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).
About 90 percent of the volcano is covered with lava flows less than 1,100 years in age. Mauna Loa, the largest volcano on Earth, has erupted 33 times since 1843. The most recent eruption in 1984 lasted 22 days and produced lava flows which reached to within about 7.2 km (4.5 miles) of Hilo, the largest population center on the Island of Hawaiâi. Lava flows less than 4,000 years old cover about 90 percent of the volcano. HualÄlai, the third most active volcano on the Island of Hawaiâi, has erupted three times in the past 1,000 years and eight times in the past 1,500 years.
