Volcanic Maps

This reference map depicts new vents and lava flows that erupted within Halema‘uma‘u crater at the summit of Kīlauea from September 14–16, 2026.

This thermal map of the summit of Kīlauea was constructed from images collected during a morning overflight on September 16, 2026. The map shows two small but active flows in the northwest portion of Halema‘uma‘u crater, erupting from new vents that opened in the past two days.

This reference map depicts new eruptive vents and lava flows in Halema‘uma‘u crater at the summit of Kīlauea since September 14, 2026.

This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. Most of the data for this map were collected during a USGS Hawaiian Volcano Observatory helicopter overflight on August 28, 2026, so the provided statistics are reflective of the entire eruption through episode 54 on August 25.

This map depicts cumulative tephra thicknesses for the Kīlauea summit eruption in areas southwest of the Halema‘uma‘u eruptive vents as of July 29, 2026.

This thermal map shows the summit of Kīlauea hours after the end of episode 52 lava fountaining on July 29, 2026. The lava flow produced by this fountain mainly flowed along the southern perimeter of the crater floor, and was stalled by the time of the overflight. However, several small breakouts were still active in several areas.

This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. Most of the data for this map were collected during a USGS Hawaiian Volcano Observatory helicopter overflight on June 30, 2026, so the provided statistics are reflective of the entire eruption through episode 50 on June 27.

This map shows thickness values for lava flows within Halema‘uma‘u crater from the Kīlauea summit eruption that began on December 23, 2024.

This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. Most of the data for this map were collected during a Hawaiian Volcano Observatory helicopter overflight on June 9, 2026. As such, the provided statistics are reflective of the first forty-eight episodes of the eruption through June 1, 2026.

This map shows lava flow and tephra accumulation at the summit of Kīlauea volcano associated with episode 48 of the ongoing eruption in Halemaʻumaʻu that started on December 23, 2024, using data recorded by the Italian Space Agency's (ASI) COSMO-SkyMed Second Generation satellite constellation.
