Overview

• Episode 32 began around 6:35 a.m. HST on Sept. 2 and ended at 8:01 p.m., with lava fountains reaching about 150 meters (500 feet).
• Multiple vents at the summit were active, covering roughly 40–50% of Halemaʻumaʻu’s floor with about 12.5 million cubic yards (337 million cubic feet) of lava.
• USGS estimated roughly 50,000–55,000 tons of sulfur dioxide were released, prompting National Weather Service advisories about vog and downwind air-quality impacts.
• All activity remained within the crater inside Hawaiʻi Volcanoes National Park; the alert level is Watch with Aviation Color Code Orange and no homes were threatened.
• HVO attributes the recurring episodes to magma rising along the same pathway at about 3.8 cubic meters per second and continues 24/7 monitoring and public guidance on hazards including Pele’s hair, ash, unstable rims and rockfalls.
