A northward-looking helicopter view of Colima volcano on February 8, 1999 shows the steaming lava dome and active lava flows with Nevado de Colima in the background. A single flow originated from the summit dome, but the light-colored topographic high on the upper SW flank caused the block lava flow to split into separate lobes. The easternmost lobe can be seen here descending diagonally to the lower left, with other lobes farther to the left. The lava flow from 1991 was completely covered by the new lava.
