Not all the fissures were still active, it added.
The USGS Hawaiian Volcano Observatory said that as of Friday afternoon, spatter and lava were accumulating primarily within a few dozen yards from the crack.
Janet Babb, a spokeswoman for the observatory, said by telephone that the eruptions could carry on "for weeks or months".
Scientists forecast more eruptions and more earthquakes, perhaps for months to come. Hawaii's Department of Transportation said there was no damage to roads that had been reported. "It kind of gets you nervous".
Gabbard said more than 1,800 residents in Leilani Estates and Lanipuna Gardens have been ordered to leave their homes since Thursday, when public works officials first reported steam and lava erupting from fissures in a road.
Gary McMillan said his home is about 3,000 feet (914 meters) from one of the fissures in Leilani Estates. Magma moving through Kilauea set off the earthquakes, said geologists, who warned of aftershocks. "This is unfortunately not the end".

► Neal also said that Friday's large natural disaster caused major large collapses, and that Big Island residents should expect several more earthquakes and aftershocks.
But on Saturday, officials said the danger was too high and the earliest residents could go back would be Sunday.
"Until we see quake activity dying down and the ground stops moving, it's likely that this activity is going to continue", said Tina Neal, a scientist in charge at the USGS Hawaii Volcano Observatory, after a community meeting attended by about 300 people on Friday.
"The people that are choosing to stay there are really putting themselves at risk from the sulphur dioxide", she said.
Although no significant lava flows have yet formed, additional outbreaks of lava, which can reach temperatures of about 2,100 degrees Fahrenheit (1,150 Celsius), were expected. "It felt nearly apocalyptic".
The volcanic instability at Kilauea, one of the world's most active volcanoes and Hawaii Island's youngest, began Monday under the eastern flank of the volcano, an area known as the East Rift Zone.
Lava flows from the volcano have covered 48 square miles, according to the USGS.
