The Latest on the eruption of Kilauea volcano on Hawaii's Big Island (all times local):
A volcanologist says there's just no telling when Kilauea's volcanic activity will subside.
Janine Krippner of Concord University in West Virginia says much of what is happening is below the earth's surface on Hawaii's Big Island, making it tough for experts to say for certain.
Charles Mandeville of the U.S. Geological Survey's volcano hazards program says Kilauea has produced similar eruptions several times in the past 2,000 years.
Ash coming out of the volcano's summit can be a nuisance for area residents, though people are unlikely to be at risk as the park surrounding Kilauea has been closed and evacuated.
Mandeville says a larger hazard is lava flowing and hot, toxic gases coming out of open fissure vents in the middle of housing and infrastructure.
Hawaii authorities are handing out masks to protect people from ash as residents brace for an explosive eruption at the summit of Kilauea volcano.
One such eruption occurred Thursday. But most people found only thin coatings of ash, if they saw any at all. Winds blew much of the 30,000-foot (9,100-meter) plume away from people.
Joe Laceby of the town of Volcano says the ash felt like sand at the beach. He says it was a bit of an irritant but not too bad.
Laceby sealed windows and cracks in his home with cellophane wrap to keep out ash and volcanic gases. He has gas masks to protect himself from the toxic fumes and ash.
The explosion at Kilauea's summit came shortly after 4 a.m.
