A view of the lava channel erupting from fissure 3 on the Northeast Rift Zone of Mauna Loa. Near the vent, the lava channel moves at around 26-36 feet per second (8.2-11 meters per second). Farther downslope, the wide lava flow front is advancing more slowly, at an average rate slower than 20 feet (6 meters) per hour. USGS image by M. Patrick.
