Hawaii's Kīlauea volcano erupted explosively early Thursday, tossing boulders hundreds of feet and sending a plume of ash about 30,000 feet (9,144 metres) into the predawn sky. "They didn't hear it", Ms Aton said. Those came after days of earthquakes.
"Hawaiian Volcano Observatory reports that an explosive eruption at Kilauea's Summit has occurred", County of Hawaii Civil Defence said in a phone alert.
One person was killed by falling debris from the largest eruption.
Time lapse images taken from a camera at the Gemini Telescope on the Big Island captured the eruption plume just before sunrise. "We also have masks if needed and have a safe place for people to be". It wasn't as much as she expected, she said.
The lava lake had drained from the summit crater a number of the months previous - the scenario now being repeated.
Residents as far away as Hilo, about 30 miles from Kilauea, were starting to notice the volcano's effects.
The masks do not protect against sulfur dioxide, a toxic gas that is still seeping from 21 fissures caused by volcanic activity.

So far, Congolese medics have identified 44 suspected cases of Ebola , with three confirmed by lab tests. Salama said that isolation and rudimentary management facilities had been set up in Mbandaka.
Though disruptive, even painful for people living near Kīlauea - especially those who have already lost their homes - the eruption will not significantly affect life on the rest of the Big Island, Poland said.
Anyone with respiratory difficulties, such as asthma or emphysema, should limit exposure to the ash, Green said. That said, he is happy is there to help those in need. The earlier limit was up to 10,000 feet (3,000 meters). The crews of the aircraft are ordered not to enter the airspace above the volcano within a radius of 8 km around the crater. "You should shelter in place if you are in the path of the ash plume".
The National Weather Service issued ash fall advisories for the Big Island through 6 p.m. Geologists said the result would likely release trapped steam rather than lava, similar to the explosions at Kilauea in 1925.
Lava spits out from a fissure created by the eruption of Kilauea, on the big island of Hawaii. It is one of the most active in the world and has been erupting continuously for more than 30 years.
"There's so many variables". It's complicated, like a bad Facebook relationship status.
"We're beginning to see the cycle of clogging and pressure building and then the blast", Klemetti said.
