Current Aviation Color Code: YELLOW
Previous Aviation Color Code: ORANGE
Issued: Saturday, February 3, 2024, 8:10 AM HST
Source: Hawaiian Volcano Observatory

Volcanic Activity Summary:
Earthquake and ground deformation rates extending from Kīlauea summit southwest along the Koa‘e fault system have decreased significantly over the past 24 hours. The intrusion of magma into this area appears to have slowed, and the likelihood of an eruption has decreased.
Accordingly, the USGS Hawaiian Volcano Observatory (HVO) is lowering the Volcano Alert Level for ground-based hazards from WATCH to ADVISORY and the Aviation Color Code from ORANGE to YELLOW.
In total, more than 3,000 earthquakes were recorded over the past week during this event, which coincided with ground deformation patterns indicative of magma moving from beneath the summit to the southwest under the Koa‘e fault system. More information on this intrusive activity will be available in the Kīlauea daily update published later today. Additional details on this event can be found in previously published official notices:

HVO continues to closely monitor Kīlauea for signs of renewed activity. Should volcanic activity change significantly, a new Volcanic Activity Notice will be issued.
Hazards are still present on Kīlauea and are described below. Residents and visitors should stay informed and follow County of Hawai‘i and Hawaiʻi Volcanoes National Park guidelines.
