Acting Mayor Wil Okabe says officials are trying to confirm a fourth vent.
He says two homes have burned. He says one owner lives on the U.S. mainland and officials are trying to find the owner of the second home, who is likely in a shelter. Officials are trying to confirm the extent of the damage, but Okabe says the houses likely burned completely.
Some residents living near spattering lava in Hawaii said Friday morning they were frustrated that they were not being allowed to go home.
Hawaii County issued a mandatory evacuation order for neighborhoods near the lava flow in the mostly rural Puna district of the Big Island. In addition to the danger from lava, civil defense officials are warning the public about high levels of sulfur dioxide.
Brad Stanfill says the lava is more than three miles (5 kilometers) from his house but he's still not being allowed in. He wants to go home to feed his pets and check on his property. He's concerned about reports of looting.
One woman angrily told police guarding Leilani Estates she was going into the area and they couldn't arrest her. She stormed past the police unopposed.
