HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE U.S. Geological Survey Monday, January 20, 2025, 8:25 AM HST (Monday, January 20, 2025, 18:25 UTC)Current Volcano Alert Level: WATCH Current Aviation Color Code: ORANGE Activity Summary: The summit eruption at Kilauea?volcano that began on December 23 ended its fourth eruptive phase around 10:10 a.m. H.S.T., January 18. Glow from the vents and the crater floor has been persistent since as breakouts and overturning crustal plates expose molten lava. This indicates that lava remains close to the surface of Halema?uma?u within Kaluapele (the summit caldera). No unusual activity has been noted along Kilauea’s East Rift Zone or Southwest Rift Zone. Summit Eruption Observations: The summit eruption at Kilauea?volcano that began on December 23 ended its fourth eruptive phase around 10:10 a.m. H.S.T. yesterday January 18. Activity greatly decreased at approximately 9:45 a.m. when the north vent fountain and associated lava flow stopped erupting, and south vent activity greatly diminished at the same time. Lava continued to flow from south vent for another 20 minutes at a much reduced rate, and stopped erupting by 10:10 a.m. Since then, there has been glow from both vents, and from the crater flow as breakouts and overturning crustal plates expose molten lava. This indicates that lava remains close to the surface. Pele's hair formed in earlier stages of Episode 4 may continue to be remobilized by winds within the National Park and in nearby communities over the next few days (see Hazards section below). Analysis: The current eruption at the summit of Kilauea is the sixth eruption since 2020 within Halema’uma’u crater, which sits inside the southern part of Kaluapele. The recent summit eruptions have lasted from one week to more than a year. Like most of the other eruptions, this event began with vigorous lava effusion and volcanic gas emissions from an initial fissure system. The current eruption is marked by episodic fountaining not seen in any of the other eruptions. There have been four fountaining episodes to date lasting from a few hours to over a week. The onset of fountaining of each episode is accompanied by strong deflation of the summit region. Pauses or periods of repose between all of the fountaining episodes are marked by an immediate change from deflation to inflation of the summit as magma recharge repressurizes the magma chamber. The prior four episodes all began after the Uekahuna tiltmeter recorded between 6 and 12 microradians of inflationary tilt. The Uekahuna tiltmeter has recorded about 2 microradians of inflationary tilt in past 24 hours and is currently inflating at a rate of 2 microradians per day. If this relatively high rate of inflationary tilt continues and magma remains high in the vent as indicated by strong glow at night, it suggests that there is a high probability that the fifth fountaining episode could begin sometime between Tuesday January 21 and Friday January 24. If the rate of inflation slows, the probable window of time for resumption of activity would be longer. |
