At least 117 homes have already been taken by lava in the Lanipuna Gardens and Leilani Estates neighborhoods where lava surfaced more than a month ago.
Okabe describes the area as a mix of vacation rentals and year-round residences.
A growing river of molten rock flowing from the fissure at the foot of Kilauea Volcano is believed to have demolished scores of homes and filled in a small bay at the eastern tip of Hawaii's Big Island, civil defence officials said on Tuesday.
On Sunday, the flow crept toward Kapoho Bay, a roughly 1,000-foot-wide ocean retreat.
"Over the course of essentially two days, that entire area was covered by lava", Dr Stovall said.
And the lava keeps spewing, swallowing homes and igniting fears of more destruction to come.
"He was very depressed", Okabe said of how Kim felt about losing his vacation home.
Snyder said from now on, the county will provide counts of homes destroyed.
About 7.7 square miles of land have been covered by lava.
Residents of the Puna District in East Hawai'i are reeling from this latest blow, many displaced, seeking shelter with friends, relatives, and in community facilities throughout the island.
Some chose to stay in the area, which now has no power, cell reception, landlines or county water, officials said.
"It's a attractive blue day, but it really seems eerie up there, lots and lots of ash covering areas near Jagger Museum and the earthquakes really make things seem very unsettled", she said.
There have been 9,900 earthquakes on the island since May 4 as a result of the geological activity, the USGS said, including about 500 near Kilauea's summit over the weekend, according to CNN.
They anxious their house would be spared by the lava but rendered inaccessible, leaving them stuck with the mortgage for an abandoned home and a fire insurance policy that was of no value, she told Reuters.
