And the dramatic explosion reactivated several fissures and opened a new one in the last 24 hours.
The state’s Civil Defense has issued new policies to keep the population as safe as possible from the volcanic fumes and ash fall.
Kilauea is releasing the extremely irritating sulphur dioxide gas (SO2), which can be “especially dangerous for elderly, children and people with respiratory problems,” authorities said.
The Civil Defense warned those living in areas downwind of rifts they may intermittently experience higher levels of fumes than civilians living in other areas.
People with breathing problems should avoid being outdoors and leave the area if deemed necessary
In a statement, the authorities said: “People with breathing problems should avoid being outdoors and leave the area if deemed necessary.”
Locals have also been warned of the dangers of volcanic smog – called vog – a haze containing volcanic dust and gases, which can cause headaches and irritation to the lungs and eyes, according to the University of Hawaii at Hilo.
AccuWeather meteorologist Faith Eherts said: “Short-term symptoms to exposure to vog include itchy eyes, a sore throat, coughing, nausea and trouble breathing.
“These are especially pronounced for the elderly, the very young and anyone with pre-existing respiratory and cardiovascular health issues such as asthma.

“Smoke and other particles in the air such as sulfur dioxide enter the bloodstream through the lungs, leading to longer term health problems down the road.”
The Civil Defense is distributing one mask per family member to help civilians venturing outside to filter the ash.
A third shelter has been opened on Pohaku Circle in Keaau, near Puna, to help people with breathing problems.
The Civil Defense said: “The shelter will cater specifically to people with breathing issues, but everyone is welcome.”

Hawaii volcano eruption: 29 earthquakes have been recorded in Hawaii in the last 24 hours
The Hawaiian Volcano Observatory (HVO) has raised the number of fissures to 21 after a new one opened down rift of Makamae Street in Leilani Estates, an area that has been already evacuated earlier this month over the fear of spreading lava.
The unrelenting activity of the volcano and the level of lava dropping in the main crater is also triggering earthquakes.
The Hawaiian soil has been shaken by tremors 29 times in the last 24 hours, with a 3.6 magnitude quake being the most aggressive so far.
The USGS Hawaiian Volcano Observatory said in a statement: “As deflation continues, strong earthquakes in the area around Kilauea Volcano’s summit are expected to continue and may become more frequent.”
