September 26, 2024—InSAR image of Kīlauea deformation associated with recent eruption

This map shows recent deformation at Kīlauea over the timeframe of September 14–26, 2024, during which an eruption occurred on the East Rift Zone. Data were acquired by the European Space Agency's Sentinel-1A satellite. Colored fringes denote areas of ground deformation, with more fringes indicating more deformation. Each color cycle represents 2.8 cm (1.1 in) of ground motion. The symbol in the upper left indicates the satellite's orbit direction (arrow) and look direction (bar) and north is up on the figure. The bulls-eye feature southwest of Kaluapele (Kīlauea summit caldera) indicates ground subsidence over this time period as magma moved from summit storage regions and intruded underground into the area west of Nāpau Crater on the East Rift Zone. The butterfly-shaped feature west of Nāpau Crater indicates ground surface extension over this time period as the magma intruded, resulting in the eruption in and west of Nāpau Crater from September 15–20, 2024. Lava flows from this eruption, which covered 156 acres with new rock in and near Nāpau Crater, are shown in pink and the eruptive fissures are shown in light purple.  For information about interpreting interferograms, see this "Volcano Watch" article: Reading the rainbow: How to interpret an interferogram.
