Highway 130, portion of 137 to reopen

Lava flows Saturday around islands in the lava channel. The direction of flow is from the upper right to lower left. Field crews can make a rough calculation of velocity by timing large blocks as they pass between two landmarks that are a known distance apart. (U.S. Geological Survey/Special to West Hawaii Today)
At the Kapoho coast, lava enters the ocean along the northern margin of the flow field on Saturday. (U.S. Geological Survey/Special to West Hawaii Today)
Lava from fissure 8 is fed into a channel that travels about 8 miles to the sea on Saturday. A plume marks the location of fissure 8, visible in the upper right; a small plume in the upper center marks the location of fissure 22. Each morning, HVO field crews conduct an overflight of the lava channel to determine if there have been any overflows. Intermittent small, short-lived overflows have occurred, but these overflows rarely extend beyond the existing flow field.
Lava was entering the ocean over a broad area Saturday morning. This image shows an active entry area along the northern flow front at Kapoho. View to the south. (U.S. Geological Survey/Special to West Hawaii Today)
Fountains from the fissure 8 spatter cone continue to supply lava to an open channel. The spatter cone on Saturday was about 180 feet at its highest point. As observed during this morning's helicopter overflight, the fountains rarely rise above the rim of the spatter cone. (U.S. Geological Survey/Special to West Hawaii Today)
