Kīlauea images of eruptive activity, field work, and more.
Pāhoehoe lava flows paved the floor of Nāpau Crater during the recent eruption on Kīlauea middle East Rift Zone. Pāhoehoe is characterized by smooth, billowy, and ropy surface textures. Recent lava flowed over tephra that previously coated this area of the crater floor.

A helicopter overflight on September 20, 2024, allowed for aerial visual and thermal imagery to be collected at the middle East Rift Zone eruption site on Kīlauea. This thermal map shows that the eruption at Nāpau Crater had paused this morning, with no fountaining or active lava on the surface.

USGS Hawaiian Volcano Observatory field monitoring crews reported minor spattering and small fountains at one end of the vent as of 8:30 a.m. HST on September 20, 2024. By 10 a.m. HST, eruptive activity had paused but the eruptive vents continued to emit volcanic gas and steam, visible in this aerial photograph.

USGS Hawaiian Volcano Observatory field crews reported small fountains and lava flows erupting from one of the western fissures just before 9 a.m. HST on September 20, 2024. By 10 a.m. HST, that activity had ceased and the middle East Rift Zone eruption of Kīlauea had paused. USGS photo by M. Patrick.

From the floor of Nāpau Crater, USGS Hawaiian Volcano Observatory geologists observed where recent lava flows covered the trail in the crater. The trail is visible in the lower center portion of the photograph, as a track in tephra deposited during previous eruptions in the area. USGS photo by M. Patrick.

USGS Hawaiian Volcano Observatory gas scientists measured the composition of gases being emitted by Kīlauea during the waning phase of the middle East Rift Zone eruption on September 20, 2024. They used a FTIR spectrometer, which measures how the plume of gases being emitted at the eruption site absorbs infrared energy.

USGS Hawaiian Volcano Observatory geologists conducted a reconnaissance overflight of the eruption near Nāpau Crater on the middle East Rift Zone of Kīlauea. They observed a 150-m-long (nearly 500 feet) fissure west of the crater erupting lava that is flowing in the crater via a channel more than 50 meters (about 164 feet) wide.

The 150-m-long (nearly 500 feet) fissure erupting west of Nāpau Crater within Hawaʻi Volcanoes National Park began erupting yesterday, September 18, around 3:15 p.m. It's part of an eruptive sequence that began in this area the night of September 15, 2024.

During the USGS Hawaiian Volcano Observatory reconnaissance overflight the morning of September 19, geologists observed the fissure west of Nāpau Crater generating a lava flow that travels northeast before cascading into the crater on the remote middle East Rift Zone of Kīlauea. This aerial view is looking in a south direction, from north of the eruption site.

USGS Hawaiian Volcano Observatory geologists conducted a reconnaissance overflight of the eruption near Nāpau Crater on the middle East Rift Zone of Kīlauea. They observed lava cascading over the rim of the crater from a channel more than 50 meters (about 164 feet) wide. Lava is contained within Nāpau Crater and now covers about two thirds of the crater floor.
