The Puu Oo eruption on the East Rift of Kilauea
Volcano in Hawaii began in 1983 and is still going strong. R. Hoblitt, U.S. Geological Survey, took this photo of
an active pahoehoe lava flow on May 9, 2002, near the Royal Gardens Subdivision. The flow
lobe is about 2 feet across, has a temperature near 2000 degrees F, and a viscosity near
that of liquid honey. The red areas near the center and bottom of the photo show where the
crust is stretching -- exposing the hotter interior of the flow. The flow moves slowly,
only a few inches per minute. Return to Archive or go to Next Photo. |
