Around 3:20 p.m. HST on September 29, 2021, the USGS Hawaiian Volcano Observatory (HVO) detected a glow in Kīlaueasummit webcams suggesting that an eruption has begun in Halemaʻumaʻu crater. This thermal image from the webcam at 3:38 pm shows cracks that have opened on the surface of the recently active lava lake in the Halemaʻumaʻu crater. (HVO / Special to West Hawaii today)

Around 3:20 p.m. On Wednesday, the observatory announced that it had discovered a glow in the webcam images of Kilauea Summit, indicating that an eruption had begun in the Halemaʻumaʻu crater in the Summit Caldera of Kilauea in Hawaii Volcanoes National Park.

Webcam images show cracks at the foot of Halemaʻumaʻu crater that create lava flows on the surface of the lava lake, which was active until May, the observatory announced on Wednesday afternoon.

The US Geological Survey’s Hawaiian Volcano Observatory increased then Kilauea’s volcano warning level from WATCH to WARNING and its aviation color code from ORANGE to RED as this new eruption and associated hazards are assessed.

The observatory said activity was limited to Halemaʻumaʻu on Wednesday afternoon and the Hazards will be reassessed in the course of the eruption.

The observatory said the eruption occurred in an enclosed area of ​​the park and that it was high Volcanic gas is the main hazard as it can have far-reaching effects in the direction of the wind. « Large amounts of volcanic gas – mainly water vapor (H2O), carbon dioxide (CO2) and sulfur dioxide (SO2) – are produced during eruptions of the Kilauea volcano released continuously. When SO2 is released from the summit, it will react in the atmosphere creating the visible haze known as vog (volcanic smog) that has been observed downwind of Kilauea, ”HVO said. « Vog poses potential airborne health hazards for residents and visitors, harms agricultural crops and other crops, and affects livestock. »

Fanned by southerly winds, the Vog normally moves through Ka’u District and first reaches areas such as Pahala, Naalehu and Ocean View before being caught in a sea breeze that takes him towards West Hawaii and on to land.

The observatory said additional hazards include Pele’s hair and other light volcanic glass fragments from the lava fountains falling downwind of the stomata and pollinating the ground within a few hundred meters of the openings. Strong winds can blow lighter particles at greater distances. Residents should minimize exposure to these volcanic particles, which can cause skin and eye irritation.

Other significant hazards also exist in the vicinity of the Kilauea Caldera due to the instability of the Halemaʻumaʻu crater wall, cracking in the ground and rock falls may be amplified by earthquakes in the area closed to the public.

Officials said Wednesday that increased earthquake activity and ground swelling had been detected, and raised the alert levels accordingly.

Kilauea had a major eruption in 2018 who destroyed numerous homes and displaced thousands of residents.
