Panoramic image showing the fissure 3 lava channel at a high elevation on Mauna Loa's Northeast Rift Zone. In field, Hawaiian Volcano Observatory scientists measure how fast the lava is flowing. On average, the velocity of lava within the channel is estimated to be flowing at a rate of nearly 10 meters per secon (32 feet per second). USGS image by H. Dietterich.
