This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. The data for this map were collected during a Hawaiian Volcano Observatory helicopter overflight on November 24, 2025; as such, the provided statistics are reflective of the first thirty-six episodes of the eruption through November 9. A thirty-seventh lava fountaining episode occurred November 25, but its lava flows will be mapped in full during the next overflight, likely sometime next week.

Eruption statistics through episode 36:
Vent elevations: 3,445 feet (1,050 meters) above sea level
Vent level above surrounding lava: 130 feet (40 meters)
Vent level below crater rim: 295 feet (90 meters)
Average lava elevation: 3,219 feet (981 meters)
Average lava thickness: 210 feet (64 meters)
Total lava extent: 950 acres (384 hectares)
Total lava volume: 49.0 billion gallons (185.5 million cubic meters)
