Hawaii County Civil Defense officials said that late Saturday night a lava flow moving at 300 feet-per-hour reached Highway 137, one of the main highways in the Puna district. A section of the road was shut down.
The officials also reported that a lava flow had reached the Pacific Ocean. Lava entering the water creates laze, a type of volcanic gas that may endanger nearby residents.
Laze is formed when hot lava makes contact with the ocean, sending hydrochloric acid, steam and fine glass particles into the air.
Brushfires caused by the lava forced the agency to ask residents on Kamaili Road to “evacuate the area immediately” on Saturday around 6:40 p.m. local time. County and state firefighters were going door-to-door in that area informing residents of the evacuation and assisting them when necessary.
“Everyone needs to stay clear of this area,” the agency said.
The flows began forming on May 3, after several fissures opened up in the Leilani Estates subdivision of Puna, located on the volcano’s lower east rift zone. Since then, at least 44 structures have been consumed by lava, including dozens of homes.
On Friday, lava engulfed four more homes and a flow from fissure 20 crossed a part of Pohoiki Road, near Malama Ki Place, cutting access to a remote neighborhood with 40 homes. As a result, four people had to be evacuated, according to officials.
Over the past two weeks, an estimated 1,700 residents have been evacuated from Leilani Estates and neighboring Lanipuna Estates subdivisions.
The U.S. Geological Survey’s Hawaiian Volcano Observatory, which has been monitoring the eruption, said that several fissures have merged to form a “continuous line of spatter and fountain” in an update sent Saturday afternoon.
Hawaii County Civil Defense administrator Talmadge Magno said at a news conference Saturday afternoon that one man sustained a “serious” injury after a spatter of lava hit his leg while he was sitting on the porch of a house earlier in the day.
The “lava bomb hit his leg and he got injured,” Magno told reporters. “The injury was quite bad.”
Aerial footage of the lava shows several large flows from a number of fissures swallowing the land in a fiery, loud and explosive display.
Janet Williams-Downing, a resident of Nanawale Estates, a few miles north of Leilani Estates, told HuffPost that she has been feeling about 100 earthquakes every day with “a little shake every once in a while.”
“You can hear the explosions” from the fissures, Williams-Downing told HuffPost in a message. “It sounds like a war zone right outside my door.”
Williams-Downing said that the explosions and sounds similar to that of “jet engines” are normal now that numerous fissures have been cracking open and spewing lava for nearly two weeks.
“It was scary at first with all the explosions and not knowing which way the lava was going to go,” she said.
A crater on Kilauea’s summit erupted with a giant ash plume on Thursday, launching ash and volcanic debris up to 30,000 feet high. As expected, more eruptions followed and on Saturday, another large ash plume could be seen exploding from the Halema‘uma‘u Crater.
Earlier Saturday, Hawaii County Civil Defense asked residents between Kamaili Road and Pohoiki Road, located southwest of Leilani Estates, to decide whether they wanted to voluntarily leave the area.
Officials believe the active flows are headed in the general direction of MacKenzie State Park, located on the island’s eastern coast.
This story has been updated with officials reporting the closure of part of Highway 137 and a lava flow reaching the ocean.
