Changes in seismic velocity and earthquake rates at Kīlauea from July to mid-August 2024

Changes in seismic velocity and earthquake rates at Kīlauea from July to mid-August 2024. Changes in seismic velocity with time are shown in the top panel. The bottom panel shows earthquake rates with time for the same period. The dashed magenta line indicates the opening of cracks and fractures as the magmatic intrusion began in the ERZ. The continued decrease in seismic velocity seen to the right of the magenta line reflects continued intrusion of magma into the region.
