Hawaii National Guard prepares for air evacuations if lava cuts off key evacuation route

An air evacuation of the portions of Lower Puna that are threatened by the Kilauea volcano eruption could be accomplished within four hours if that becomes necessary because of damage to ground transportation routes, according to Hawaii Army National Guard commander Brig. Gen. Kenneth Hara.

In a briefing at Hawaii County Civil Defense headquarters, Hara told state, county and federal officials that he has arranged for two Sikorsky CH-53 Sea Stallion helicopters to be available for evacuation missions now that lava from the Lower East Rift Zone has flowed to the sea and severed Highway 137 along the coast.

The movement of that river of the lava means there is only one ground evacuation route available left for an estimated 1,000 residents who are still in homes scattered across on thousands of acres of rural land in the Kalapana area, including Opihikao, Black Sand Beach subdivision, Kalapana Seaview Estates, Puna Beach Palisades and Kahena.

Janet Snyder, spokeswoman for Hawaii Island Mayor Harry Kim, said the Sea Stallions can ferry up to 43 people out of the area at a time. One of the helicopters is already on Hawaii island, and the other is expected to arrive today, she said.

“They can basically evacuate a whole subdivision of 500 people within two hours,” Snyder said.

Hara has been appointed head of a “dual-status command Joint Task Force 5-0” in response to the eruption, an arrangement gives him authority to command both National Guard and active military forces to carry out operations in response to the emergency in Puna.

Hara reported that he can also call on Sikorsky UH-60 Black Hawk helicopters from the 25th Combat Aviation Brigade at Wheeler Army Air Force Base on Oahu if they are needed.

An air evacuation is emerging as a real possibility because scientists know that lava has been passing beneath Highway 130 along the East Rift Zone and surfacing in areas in and around Leilani Estates since the latest eruption began on May 3.

That suggests it is possible new fissures could open west of Leilani that would cut Highway 130, leaving a large area from MacKenzie State Recreation Area to Kalapana without a ground evacuation route.

Hawaii Civil Defense Agency Administrator Talmadge Magno said Tuesday the cracks in Highway 130 that closed the route for a time earlier this month have not been widening. The highway reopened after crews dropped steel plates across the cracks to provide safe access for traffic.

“Our state highways folks and our public works folks say they can try to keep it open as long as possible,” he said. “Right now, they’ve got the steel plates on it. Whether it is dumping out huge quantities of material just to fill cracks and so forth, they’ll do it.”

“We’re looking at some alternate routes, but everything’s going to have to cross that East Rift, so we’re limited on alternatives, but part of our messaging all the time has been to let these people know that this is coming down, that possibly they’re going to get isolated, so they need to make that decision,” Magno said. “If you need to be in Hilo or another place for work, you need to start considering moving out.”

The one road that could direct traffic away from the East Rift eruption area is Chain of Craters Road. State and federal officials have been planning to reopen that route, which extends from Kalapana to the Hawaii Volcanoes National Park, but construction has not yet begun on that project.

Chain of Craters was reopened by the county as an emergency access route when another lava flow threatened Pahoa in 2014 and 2015, but lava from Kilauea has once again blocked the route. The flow that caused the latest blockage ceased last year.

Gov. David Ige told reporters Tuesday that “we are evaluating reopening Chain of Craters Road, but it’s a very dangerous road, it hasn’t been used for a long time, so we do have county and highway people really looking at it and trying to prepare it should it be necessary.”

Ige said transportation officials are “also looking at other alternative routes and trying to decide what would make the most sense in terms of providing safe passage. We do know that we need to keep roads open so that residents can get around, and we’re committed to doing that in the best and safest way that we can.”
