Kilauea volcano lava now threatening Pahoa town, sole access roads to Hawaii Island’s eastern tip
A lava flow from Kilauea volcano continued to advance toward residential areas in Hawaii Island’s Puna district this week, turning toward the town of Pahoa and the only access roads connecting it to the rest of the island.
The front of the slow-moving lava flow, which we reported last Friday was threatening the residential subdivision of Kaohe, this week bypassed neighborhood homes and began moving northeast towards neighboring Pahoa. On Mon., Sept. 17, the flow crossed the Wao Kele o Puna Forest Reserve boundary and into forested vacant lots within Kaohe. As of this morning, however, the 11.6-mile flow had entered open ground roughly three miles upslope from Pahoa.

The USGS Hawaiian Volcano Observatory’s current projection anticipates the flow will cross two critical access routes within the next few weeks. Keeau-Pahoa Road (Pahoa Village Road), a small two-lane outlet running through Pahoa town, and the larger Highway 130 (Pahoa Bypass Road), are the only arteries connecting the small communities of Hawaii Island’s easternmost tip to the rest of the island. Both are threatened by the approaching flow.
As of this morning, the front of the flow was still 1.5 miles upslope from Apaa Road, a small back road connecting to Keeau-Pahoa Road. The latest Hawaiian Volcano Observatory estimates suggest the flow could cross Apaa Road within a week, and Keeau-Pahoa Road (Pahoa Village Road) in 11 days.

Situated 20-miles southeast of Hilo, Pahoa and Kaohe are part of Hawaii Island’s Puna district, which encompasses the island’s eastern-most tip. The current flow, which began on June 27, is part of a long-running eruption from the Puu Oo volcanic cone, on the eastern flank of Kilauea volcano. Eruptions in the area have been continuous since 1983. According to USGS statistics, lava from the three-decade plus eruption has already destroyed 189 structures and claimed eight miles of highway.
Hawaii County Civil Defense officials have yet to order evacuations of Pahoa or Kaohe. A Friday morning web update from the agency stated that the flow did not pose an immediate threat to the communities and that residents would be given adequate notice to safely evacuate should it become necessary.
