On September 17 at 8:36 p.m. HST, a magnitude-4.1 earthquake occurred 3 mi (5 km) south of Pāhala on the Island of Hawaiʻi at a depth of 8 mi (12 km) below sea level. The earthquake had no apparent impact on either Mauna Loa or Kīlauea.

Kīlauea summit deflation slowed and stopped by 9:00 a.m. HST. UWD tiltmeter remains flat. No surface deformation detected outside of the summit; heavy rain is producing a false inflationary peak on the Pu‘u‘ō‘ō (POC) tiltmeter.

There are currently no active lava flows. Minor deformation and seismicity are confined to the summit region. Details are in today's Kīlauea update: https://volcanoes.usgs.gov/hans-public/notice/DOI-USGS-HVO-2026-09-17T17:15:57+00:00

The north-south-west vents have had consistent strong glow and flames all night. Summit tremor and tilt began decreasing around 5 pm HST and the new vents stagnated at 8:30 pm HST. No anomalous activity or seismicity detected elsewhere.

Another new vent, vent 6, opened on the floor of Halema'uma'u crater just to the north of vent 5 and was visible just before 6 pm HST. The start of a small summit tilt drop around 5 pm HST may correlate with the opening of vent 6.

The V2 camera is now centered on the area of the new vents that opened last night north of the established vent complex.
More info in todayʻs update.

Two small breakouts occurred out at base of vent complex last night, feeding an active lava flow on the northwest corner of the crater floor. North/South/West vents continued to glow/produce spatter.

Spatter bursts and large flames are nearly continuous from the north vent tonight. Summit inflation continues and has reached a total of 15.8 microradians of inflation follow the loss of 12.7 microradians during episode 54 fountaining.
Kilauea Message 2026-09-14 18:09:26 HST
Intermittent spattering continues from the north vent cone tonight. Spattering had decreased this morning but picked up after a small portion of the cone collapsed at 3 pm HST. Summit inflation returned around 10 am HST and is continuing.
Kilauea Message 2026-09-13 18:55:37 HST
Nearly continuous spatter bursts began from the north vent around 6:30 pm HST and have picked up in intensity. Larger bursts are 35-70 feet (10-20 m) high. Tremor remains constant and slow summit inflation continues.
Kilauea Message 2026-09-13 17:02:16 HST
The tops of small spatter fountains have been visible in the north vent all afternoon, indicating magma is standing high within the vent. Slow summit inflation continues. The last precursory overflow was yesterday just before noon.
