This Oct. 25 photo provided by the U.S. Geological Survey's Hawaiian Volcano Observatory shows a sporadic breakout of lava near the Kalapana access road and lava viewing trailhead on the Big Island. Civil Defense officials on the Big Island believe the trailhead of the Kalapana viewing area is safe from a tongue of lava erupting from Kilauea volcano. Janet Babb, a geologist and spokeswoman at the U.S. Geological Survey's Hawaiian Volcano Observatory, said today that the flow front near the trailhead had stagnated.

A slow-moving tongue of lava has crept to within 100 yards of the trailhead of the Kalapana viewing area.

"Everything's pretty much stalled, the part that was nearest the trail," said Jim Kauahikaua, scientist-in-charge of the Hawaiian Volcano Observatory. "And action has resumed on the coastal plain about two-thirds or 1 mile up from the trail."
Kauahikaua said that the most recent surge eastward came just as the ongoing eruption experienced what's known as a "deflation-inflation" event, when the flow pauses and resumes.
During the pause portion of the event, the flow stopped, filling in a dip in the landscape and gobbling up a portion of the closed Kalapana access road. When the flow resumed, the breakout began feeding lava onto the coastal plane relatively far from the lava viewing area trail, easing the threat for now.
"I didn't see it move," said Civil Defense staff officer Bill Hanson. "We could not tell that it had moved."
Civil Defense believes that for now the trailhead and equipment are not at risk of inundation. Lava has resumed flowing into the ocean through the Waikupanaha entry point.
