Kīlauea images of eruptive activity, field work, and more.
The area south of Halema‘uma‘u has many ground cracks, many associated with the 2018 Kīlauea summit collapse and others associated with more recent earthquakes and ground deformation. While tephra from the ongoing summit eruption has covered and obscured many ground cracks, the deposit itself in places has deep cracks.

The north vent (right in photo) in Halemaʻumaʻu erupted a lava fountain during episode 47 at the summit of Kīlauea on May 14, 2026. It reached a maximum height of around 650 feet (200 meters). The south vent (left in photo) had intermittent spattering during the first two hours of the episode. USGS photo by L. Forster.

USGS Hawaiian Volcano Observatory geologists monitor lava fountaining in Halemaʻumaʻu at the summit of Kīlauea during episode 47 on May 14. 2026. From various locations around Kaluapele, Kīlauea summit caldera, USGS scientists check for tephra fallout, document and characterize eruptive activity, and measure the lava fountain and volcanic plume heights.

Episode 47 of the ongoing eruption at Halema‘uma‘u started at on May 14 at 3:27 p.m. HST and lasted 9 hours. This photo was taken shortly after sunset at 6:55 p.m. HST. The incandescent north vent lava fountain and its associated lava flows are seen through the vegetation at Kīlauea's summit region. USGS photo by L. Forster.

The lava fountain erupting from the north vent during episode 47 on May 14, 2026, seen here, sent light tephra into public areas of Hawai‘i Volcanoes National Park and surrounding communities to the northeast. Tephra is a general term for any fragmental material ejected during a volcanic eruption. USGS photo by L. Gallant.

The lava fountain erupted by the north vent during episode 47 on May 14, 2026, reached about 650 feet (200 m) in height. It fed lava flows that covered portions of the floor of Halemaʻumaʻu crater and the southwest side of Kaluapele, Kīlauea's summit caldera. USGS photo by L. Gallant.

Episode 47 lava fountaining at Kīlauea summit began at approximately 3:27 p.m. HST Thursday, May 14, and continued for about 9 hours. Only the north vent produced high fountains with only sporadic spattering activity from the south vent. This photo taken around 5 p.m.

Misty weather partially obscured views of episode 47 at the summit of Kīlauea on May 14, 2026. This photo was taken approximately 2 1/2 hours into the eruptive episode, which began at 3:27 p.m. HST. Only the north vent erupted a lava fountain, which fed channelized lava flows across the crater floor within Kaluapele. USGS photo by L. Forster.

Tilt record from December 1, 2025, to May 12, 2026, for tiltmeter UWD near the summit of Kīlauea, during which lava fountaining episode 38–46 occurred. Deflationary tilt is shown as a tilt “decrease” and inflationary tilt as an “increase”. Tilt variations during pauses, especially after episode 41, have led to adjustments of the forecast windows.

The arrival of misty rains during the USGS Hawaiian Volcano Observatory helicopter overflight on May 12, 2026, precluded a full imaging of the Halema‘uma‘u crater floor, but it did offer views of an ānuenue (rainbow) in front of the Kīlauea summit eruptive vents. USGS photo by P. Dotray.

From the north rim of Halemaʻumaʻu crater at the summit of Kīlauea, the lava fountain from the north vent rises above the crater rim visible in the foreground. This photograph was taken just after 10 a.m. HST, and cooled, dark-colored tephra particles falling from the lava fountain are visible, illuminated by the incandescent lava fountain the background.
