At least five homes in South Kona sustained such substantial damage during last week’s 6.0-magnitude earthquake that they’ve been deemed “destroyed,” the Hawaii County Civil Defense Agency said Tuesday.

At least five homes in South Kona sustained such substantial damage during last week’s 6.0-magnitude earthquake that they’ve been deemed “destroyed,” the Hawaii County Civil Defense Agency said Tuesday.

The handful of homes in question are among 143 properties reported damaged to Civil Defense as of Tuesday morning. Prior to that, the agency had completed 78 damage assessments — all for residential properties — which accounted for the five destroyed homes as well as 34 cases of “major” damage, 22 cases of “minor” damage, and more than a dozen “affected” properties.

Under the Federal Emergency Management Agency standards used by Civil Defense, a house is considered destroyed if it has been so heavily damaged that repair is unfeasible, including the collapse of two or more major structural components like foundations, load-bearing walls or roofs.

According to Civil Defense, at least two residential households have made requests for emergency housing assistance and were subsequently referred to the American Red Cross.

The powerful temblor struck the west flank of Mauna Loa just before 10 p.m. on Friday with its epicenter located approximately eight miles south of Honaunau-Napoopoo at a depth of roughly 14 miles below sea level. It caused power outages, widespread structural damage to homes and rockslides that blocked portions of Highway 11 and Napoopoo Road for several hours.

State road crews worked through the night to clear rocks and debris, with reports of boulders as large as 5 feet in diameter blocking the right of way. Highway 11 fully reopened around 6 a.m. on Saturday, with the piles of debris remaining on shoulders beginning to be cleared on Tuesday.

Civil Defense officials said that inspections of roads and bridges are ongoing, but so far there have been no reports of significant damage.

“We asked all departments to go look at their critical infrastructure Saturday, and there were no negative reports or any reports of anything compromised,” Civil Defense Administrator Talmadge Magno said. “I followed up again (Tuesday) for folks to get us information, and I’ve not received any. I’d say other than the rockslides on the roadways, the roads are okay.”

About 1,000 Hawaiian Electric customers in South Kona were left without power in the quake’s aftermath, the vast majority of whom were reconnected by Saturday evening, the company said in a press release.

However, according to Civil Defense, a few residents in the area were still in the dark due to outages that happened on the homeowner-side of the electrical grid.

“There was a handful of people that still had different situations,” Magno said. “When power separates on the homeowner-side, they’ve gotta bring in an electrician. So, HECO will do their side, and they did as much as they could, but there were a few that still had some issues.”

According to the U.S. Geological Survey, the quake was caused by downward flexing and tectonic stress on the oceanic plate under the immense weight of the Hawaiian Island chain — not by magma movement — with shaking felt as far away as Kauai, more than 300 miles northwest of the epicenter.

Although Civil Defense had only received reports of residential damage as of Tuesday morning, social media videos and anecdotal accounts suggest stores like Kona Walmart and multiple KTA Super Stores locations suffered minor damage from items falling off of shelves and breaking.

KTA Kealakekua saw reports of cleanup crews working through the night Friday in order to ensure the store was safe to open Saturday morning.

Kona Community Hospital located in Kealakekua had only minor damage, with all medical services remaining fully operational.

“They did have damage, but they were able to quickly resolve things and get back online,” Magno said. “They were in an emergency posture for maybe 24 hours … (but) they never shut down any services — they were always open.”

Civil Defense has seen an increase in call volumes since the long weekend, with a significant uptick Tuesday.

“It was surprisingly light on Saturday and Sunday, and we took only seven messages overnight last night,” he said, referring to Monday evening. “I guess people thought we were closed over the weekend, so now they’re calling. (Tuesday has) been very busy.”

It’s crucial that residents report earthquake damage suffered by their homes or businesses to the agency, he said, because future state and federal disaster aid will depend on that data.

“I think we’ve got a pretty good idea of the extent of the damage, but as far as the totality of who’s been impacted, I hope people report in,” he said. “By the end of the week, I’d give it, people need to let us know. Because we’ve got to push numbers up to the state and federal government, and the better the picture — the more comprehensive numbers we have — the better it is for any kind of assistance.”

When asked if any state or federal disaster declarations could be forthcoming, he said it remains a possibility.

“There’s multiple levels, so we’ve probably hit some of those levels already,” he said.

Residents can report earthquake damage to Civil Defense via its website at tinyurl.com/2s3c6cze.

The agency requests that residents include clear photos or videos while filing damage reports, and to save any receipts related to stabilization and cleanup.

Those unable to access the online forms can submit their reports over the phone by calling the agency at (808) 935-0031.
