March 12, 2026—Summary map of tephra fall after episode 43 lava fountaining at the summit of Kīlauea March 12, 2026—Summary map of tephra fall after episode 43 lava fountaining at the summit of Kīlauea
This map shows the tephra fall associated with episode 43 of Kīlauea's episodic summit eruption, on March 10, 2026. Tephra is a generic word for any material erupted by a volcano that travels through the air before landing on the ground.
March 2, 2026—Kīlauea summit eruption reference map March 2, 2026—Kīlauea summit eruption reference map
This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. As of this posting on March 2, 2026, the eruption has had forty-two episodes, with the most recent occurring on February 15.
February 26, 2026 — Thermal maps of Kīlauea summit in February 2026 February 26, 2026 — Thermal maps of Kīlauea summit in February 2026
These thermal maps at the summit of Kīlauea show the crater floor after episodes 41 and 42. Episode 41 produced a lava flow that covered much of the eastern crater floor, while episode 42 produced flows that stopped short of reaching the eastern edge of the crater floor.
February 18, 2026 — Kīlauea lava flow and tephra fall map following episode 42 February 18, 2026 — Kīlauea lava flow and tephra fall map following episode 42
This map shows lava flow and tephra accumulation at the summit of Kīlauea volcano associated with episode 42 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.
February 16, 2026—InSAR image of Kīlauea deformation associated with episode 42 of ongoing summit eruption February 16, 2026—InSAR image of Kīlauea deformation associated with episode 42 of ongoing summit eruption
This map shows recent deformation at Kīlauea, over the timeframe of February 10–16, 2026. Data were acquired by the European Space Agency's Sentinel-1A/C satellites. Each color cycle represents 2.8 cm (1.1 in) of ground movement in the direction between the satellite and the ground (range change).
