Ten days after the largest active volcano in the world, Hawaii's Mauna Loa, began erupting, activity at the volcano's Northeast Rift Zone is still going, and flows of lava have been filmed pouring down the volcano's flanks at speeds of up to 18 miles per hour.

The flow front is moving due north toward one of the island's major highways, the Daniel K. Inouye Highway, known locally as Saddle Road. However, while the lava is traveling at high speeds close to the volcano's vents—as seen in a video released by the United States Geological Survey—the lava front itself is advancing much more slowly, at an average speed of only 68 feet per hour.
