Kīlauea earthquake activity (January 26-February 2, 2024)

This video shows earthquake activity recorded by the Hawaiian Volcano Observatory at Kīlauea summit, extending southwest, from January 26-February 2, 2024, in 12-hour snapshots. 

In each image, warmer-colored circles represent more recent earthquakes within the 12-hour timeframe. Circle size represents earthquake magnitude. During this time period, over 3,000 earthquakes have been located, ranging in magnitude from less than 1 to less than 4. 

As the video shows, elevated earthquake activity began in the summit region and shifted to the southwest along the Koa‘e fault system. 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. Along with ground deformation patterns, these observations are consistent with magma moving into a dike-like body in the region.
