January 2, 2025—Kīlauea summit eruption reference map

This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u as of January 2, 2025. Since the onset of the eruption on December 23, 2024, it has covered a total of 673 acres (272 hectares) with new lava (pink area), and approximately half that area still hosts active flows (red area). The total lava volume is at least 4 billion gallons (15 million cubic meters), based on measurements from a December 27 overflight and estimates from observations of subsequent activity.
