February 3, 2024 — Summary map of recent unrest at Kīlauea Volcano

February 9, 2024
Color map showing earthquakes and ground deformation near summit of volcano

This map shows recent unrest at Kīlauea volcano. Yellow circles mark earthquake locations from January 31, 2024, through February 3, 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.  Colored fringes denote areas of ground deformation over a one-day timeframe from 6 p.m. HST on January 31 through 6 p.m. HST on February 1, 2024. More fringes indicate more deformation; each color cycle represents 1.5 cm (0.6 in) of ground motion toward or away from the satellite (the direction of motion depends on the sense of color change).  The complex patterns indicate overall deflation of the summit area as magma moved underground to the southwest, where the patterns show uplift (up to about 50 centimeters, or 20 inches) and spreading (along with subsidence) due to intrusion of a dike (a vertical sheet of magma).
