Overview
- USGS reported that three vents inside Halemaʻumaʻu erupted simultaneously on the morning of Dec. 6, local time, during episode 38.
- Sustained lava fountains rose to roughly 300–370 meters, an exceptionally uncommon display for this eruption sequence.
- A dark volcanic plume climbed above 6,000 meters, according to USGS observations.
- All lava activity stayed confined within Halemaʻumaʻu in Hawaiʻi Volcanoes National Park, and officials did not expect impacts to local airports.
- Authorities cautioned about hazardous volcanic gases and airborne glass fibers known as Pele's hair that can be carried more than 15 kilometers downwind.
