Maths News: Volcano Survivor 2
May 8, 2018Kilauea erupts in Hawaii MAY 2018.
The amazing maths of volcano eruptions.
The fastest Lava flows recorded were in Hawaii in 1950 when Mauna Loa erupted. The lava traveled at 6 miles (10 kilometers) per hour through thick forest. But once the lava flows became established and good channels developed, the lava in the channels was flowing at up to 60 miles/hour (97 kph)
Can you out run a lava flow?
You are 2 km from the volcano rim and start running.
VL = 97 kph = 1.6 km per minute (k/min)
= 60 mph
VH = 18 kph = 0.3 km/min
= 11.2 mph (miles per hr )

How long will it take for the lava to catch you?
