The Hawai`i Fire Department is reporting extremely high levels of dangerous Sulfur Dioxide gas detected in the Leilani Estates and Lanipuna Gardens Subdivisions evacuation areas.
A mandatory evacuation remains in effect for those area.
Hawai`i County officials say the heightened sulfur dioxide gas makes it even more urgent that the elderly, young and people with respiratory issues comply with the evacuation order as soon as possible.
In addition, Hawaiian Volcanoes Observatory says the active flow in Leilani Estate has subsided.
The eruption in the Leilani Estates subdivision in the lower East Rift Zone of Kīlauea Volcano that began in late afternoon ended by about 6:30 p.m. Lava spatter and gas bursts erupted from the fissure for about two hours, and lava spread a short distance from the fissure, less than about 10 m (33 feet).
HVO says that at this time, the fissure is not erupting lava and no other fissures have erupted.
HVO geologists are working near the fissure overnight to track additional activity that may occur, and other scientists are closely tracking the volcano’s overall activity.
