They added that the flow is still very active and there is no way of knowing when the eruption will end or if more lava-spewing vents will open.
As the fiery eruption of Kilauea continues to force evacuations on the Big Island of Hawaii, authorities are warning about other phenomena that could harm those in the area.
Kim, who had previously said it would take a minimum of $5 million per mile to fix roads ravaged by Kilauea, said the $12 million will help Hawaii County "focus on the critical tasks of making life better for our people affected by the eruption".
That help came Thursday after Hawaii Gov. David Ige signed a memorandum of understanding that freed up $12 million in immediate disaster relief to the island.
Lava filled Kapoho Bay and created land that now juts out almost a mile from the former shoreline.
"A lot of the ocean entries are extraordinarily unstable", Ferracane said.
Kilauea began erupting lava in a residential community on May 3.
More recently a huge river of lava that has crept several miles across the landscape to the eastern tip of the island engulfed two entire seaside housing subdivisions - Kapoho Beach Lots and Vacationland. It also includes all homes in Vacationland.
One of the areas they have been used extensively is in capturing video of the lava flow in the lower East Rift Zone coming from the fissures in Leilani Estates.
Kim told reporters in Hilo on Thursday the total includes about 320 homes in the coastal community of Kapoho. "I'm talking about 600 families". The lake was hundreds of feet deep in some places.
So too have airborne volcanic glass fibres, called "Peel's Hair", wispy strands carried aloft by the wind from lava fountains and named for the volcanic goddess of Hawaiian myth. Lava has since been pouring out of large fissures in the earth and down to the ocean.
