"What we're seeing at Kilauea is interaction between groundwater and hot rock", said Michael Poland, a geophysicist with the U.S. Geological Survey in Vancouver, Washington.
Some people in the community closest to the volcano slept through the blast, said Kanani Aton, a spokeswoman for Hawaii County Civil Defense, who spoke to relatives and friends in the town called Volcano.
A powerful but short-lived explosion occurred at the summit of the Kilauea volcano on Hawaii's Big Island, producing a massive volcanic cloud, officials said.
Tarson said the ash plume looked different than others he's witnessed because of its sheer height.
Kilauea volcano on the Big Island of Hawaii erupted from its summit early Thursday, shooting a huge plume of ash miles into the sky and prompting authorities to urge area residents to take cover.
"Ash fall was pretty localised to volcano village area and volcano national park.
So a big event that got people's attention but not with widespread impacts", Michelle Coombes said.
Following the eruption from the Kilauea summit crater, a webcam at the Hawaii Volcano Observatory captured this image of wet ash raining down and splattering on the window. The major response is to protect yourself from fallout.

Besides this, a BSF jawan posted in the border outpost at Pittal in Arnia sector was injured in the firing around 6:45 am. Earlier, the administration declared schools within 3 kms radius of global border be closed.
In the 1924 eruption, which lasted 2-1/2 weeks, one person was killed by debris shot from the crater and areas as far as 35 miles (56 km) to the southwest and 30 miles (48 km) to the east were dusted with ash, according to the USGS. Pahoa fire station on Thursday morning recorded a "red level" of sulfur dioxide, meaning it would cause choking and an inability to breathe, Fenix Grange of the Hawaii Department of Health told a news conference in Hilo.
The volcanic eruption is harming his livelihood, he said, as he owns a music retreat and cultural center on his land.
Poland said the explosion likely only lasted a few minutes and that ash accumulations were minimal, with likely trace amounts near the volcano and at the town, named Volcano.
Hazel said Thursday that it was "time to go" after the volcano sent an ash plume high into the sky following two weeks of lava eruptions from fissures that emerged on the flanks of the volcano.
As the caldera sinks further, it may set off additional steam-driven explosions, they said. The lava flow which has traveled almost two miles from the fissure seems to have stopped moving for now, though more lava flows remain possible, and geologists warn that additional fissures could open up at any time.
Hawaii County officials say the volcano on the Big Island exploded at 4:17 a.m.
Since a new zone of Kilauea began erupting nearly two weeks ago, lava has wrecked dozens of homes and forced hundreds of people to be evacuated.
