A lava flow from Kilauea volcano’s Puu Oo vent that claimed a Kalapana home last week has slowed down its movement toward other area homes for now. But the volume of lava being sent to two ocean entries near the Big Island of Hawaii residential area doesn’t appear to be lessening.
According to the Hawaiian Volcano Observatory’s daily update this morning, lava from the Puu Oo vent on Kilauea’s upslope east rift zone was still flowing through underground tubes, feeding two ocean entries on the Puna coastline. Fast-moving breakouts flows, which have occurred occasionally during the last week as inflating surface flows released pressure, are still possible. But HVO reported no such breakouts in the flow's northern and eastern sides, closest to homes in Kalapana.
On July 25, lava flows from Kilauea volcano claimed their first home in the Kalapana area in more than a decade, before reaching the ocean. Between April 1990 and February 1991, the small town of Kalapana and its Kalapana Gardens residential subdivision had been largely destroyed by lava flows from Kupaianaha, a now inactive vent two miles northeast of Puu Oo.
Though Kilauea has since continued to send Puu Oo flows to the coastline further south of Kalapana, the last flow to enter the Puna district town happened in 1992. Over the years, a handful of residents had moved back into the Kalapana Gardens area, rebuilding homes and makeshift roads over hardened Kupaianaha flows.
Of the two current ocean entry points, HVO reports the western ocean entry (farthest from Kalapana) is the most active and continuing to expand. The east entry point, closer to Kalapana, remains active.
Access to the coastline lava entry points is still being blocked by Hawaii County Police and Civil Defense officials, as Kalapana Gardens is a private residential area. For updated information on the status of the current viewing area, call (808) 961-8093.
