Residents of the Leilani Estates and Lanipuna Gardens subdivisions were ordered to evacuate, officials said.

The Hawaii Police Department and members of the National Guard were helping to enforce road closings where gas levels were deemed unsafe. As of Friday night, there were 58 National Guard soldiers working in three shifts and some 75 police officers working in 12-hour shifts, officials said.

There had been no reports of injuries or death, according to officials. As of Saturday afternoon, at least five homes had been destroyed by lava, said Janet Snyder, a spokeswoman for the office of the mayor of Hawaii County. New fissures were also reported on Saturday. Officials said firefighters were not responding to fires within the subdivisions because of the high levels of gas.

The volcanic eruptions on the southern end of the island of Hawaii prompted about 66 residents to go to shelters on Friday night and forced the closing of Hawaii Volcanoes National Park.

Lava began bubbling up through a new crack in the Kilauea volcano on Thursday evening. The eruptions came after days of small earthquakes, capped by a more powerful one with a magnitude of 6.9 that struck the south flank of the volcano on Friday at 12:33 p.m. Hawaii time.

At a standing-room-only meeting attended by residents on Friday night, officials provided updates about what to expect from the eruptions.

Residents expressed concerns about leaving their homes and the potential for looting. Others worried about the lava’s uncertain path and about pets left behind in their haste to evacuate.
