October 23, 2024—InSAR image of Kīlauea middle East Rift Zone deformation

This map shows recent deformation at Kīlauea over the timeframe of October 6–18, 2024. Data were acquired by the European Space Agency's Sentinel-1 satellites. 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). The round feature north of Nāpau and Makaopuhi Craters on the middle East Rift Zone indicates ground surface inflation over this time period as magma accumulates underground near the recent September 15–20, 2024, eruption site. Fringes at Kaluapele are due to new topography created by past lava flows, that has not yet been incorporated into our digital elevation model (DEM).
