This map shows recent unrest at Kīlauea volcano. Yellow circles mark earthquake locations from January 31, 2024 through 6:00 a.m. HST February 2, 2024, as recorded by HVO seismometers. Seismicity began early January 31 in the summit region and shifted to the southwest along the Koa‘e fault system late on January 31, 2024. In total, over 1,300 events have been detected in this area since January 31. Depths have remained consistent, 1–4 km (less than a mile–2.5 mi) below the surface, and the rates have persisted at 20-35 locatable earthquakes per hour. Magnitudes range from less than 1 to a maximum smaller than 4. Colored fringes in the map indicate areas of ground deformation from January 17–31, 2024, as measured by satellite radar. Each color cycle represents 1.5 cm (0.6 in) of ground motion toward the satellite, indicating a pattern of ground motion associated with magma accumulation. Global positioning system (GPS) instruments have recorded up to 8 inches (20 cm) of motion at stations in this area, consistent with magma moving into a dike-like body in the region.
