Kīlauea images of eruptive activity, field work, and more.
This thermal image, collected on September 14, 2023, shows features of the eruption site at the summit of Kīlauea. The image looks roughly west. The brighter colors are hotter temperatures, which are closest to the several active eruptive vents on the downdropped block within the caldera.

A helicopter overflight on September 12, 2023, allowed for aerial visual and thermal imagery to be collected at the summit of Kīlauea. The eruptive activity continues with fountains active on the downdropped block, just east of Halema‘uma‘u crater, with lava pouring west onto the crater floor.

Much of the plume from Kīlauea’s current eruption is sulfur dioxide (SO2). HVO’s gas monitoring station HRSDH has measured up to 12 ppm of SO2 at its location, nearly 2 miles (3 km) southwest, downwind of the eruption.

View from the ground of one of the vents erupting in Kīlauea caldera on September 14, 2023. The lava fountain heights at the vents reached up to about 10-15 meters (32-50 feet) and the horseshoe-shaped spatter ramparts that have accumulated on the south/downwind side of the vents are 20 meters (66 feet) high.

View from above of the fissures erupting and feeding the lava flows within Halema‘uma‘u and Kīlauea caldera. The shiny black patches are new lava flows, erupting since September 10, 2023, whereas the black dull patches tend to be spatter (molten bombs thrown out) from the vents. The vents farthest to the east have already stopped erupting molten bombs and lava.

The far eastern end of the fissure system that opened in Kīlauea caldera on September 10, 2023, was in a talus slope at the eastern end of the downdropped block. The vents associated with this part of the fissure produced weak lava fountaining that did not last long. The lava cascaded down and covers the blocks that make up the talus slope. USGS photo by D.

A Hawaiian Volcano Observatory geologist sets up remote cameras for a close-up view of the September 2023 eruption within Kīlauea summit caldera. These cameras will help capture changes in the eruption's behavior so that geologists studying the volcano can determine better the processes at work that create the lava fountains. USGS photo by D. Downs.

View of eruptive activity in Kīlauea caldera, from the west side of the caldera, looking east. The three easternmost cones, ranging from 14-20 meters (46-66 ft) fall, were far more active than the west cone in the image which was only 10 meters (33 ft) tall.

A view of the active fissure in Kīlauea summit caldera, with a chain of cinder cones as seen during an overflight on the afternoon of September 14, 2023. The vents within the cones are feeding lava flows that have covered nearly 500 acres (200 hectares) with new lava since the eruption began on September 10.

These thermal images look west and show the eruption at the summit Kīlauea on September 11 (the day after the eruption started) and on September 14. On September 11, multiple vents were active in a roughly east-west trending line and the area of active lava flows was approximately 448 acres (181 hectares).

View of the eruptive vents from the east side of Kīlauea caldera, looking west-northwest toward Kīlauea Overlook. Mid-day on September 14, 2023, the cone in the foreground of the image had mild spattering within ponded lava inside the cone. USGS photo by K. Lynn.

A row of scones in Halema‘uma‘u are actively ejecting spatter, which helps build the height of each structure. Cone heights of 20 meters (66 feet) have been measured by field teams. Of the line of vents spanning 0.8 miles (1.4 km) that were observed active during the initial phases of the eruption, only six remain active as of September 14, 2023. USGS photo by L.

During an eruption monitoring overflight mid-day on September 12, 2023, activity in Kīlauea caldera was focused on six active vents that were producing lava fountains and flows. In this photo, oriented looking toward the southwest, several inactive fissures on the northeast side of the downdropped block appear silver and brown in color.

Tephra created within approximately the first 18 hours of the eruption that began in Kīlauea caldera the afternoon of Sunday, September 10, were collected on September 12, 2023, and dried in the lab overnight. Today, these samples will be processed for various analyses to determine what the lava composition is and what minerals it might contain, such as olivine.

These tephra and spatter clasts were eruption recently at the summit of Kīlauea. They were collected from an inactive fissure on September 12, 2023, and brought back to the lab where they will be analyzed in several ways, including their density, shape, size, and chemistry. The larger clast on the bottom is about 8 inches (20 cm) long. USGS photo by K. Lynn.

From Kīlauea caldera floor overlooking the downdropped block, HVO scientists had a beautiful view of the six erupting vents on the floor of the downdropped block. HVO scientists were on the caldera floor retrieving seismic nodes, which had been deployed during the Kīlauea Seismic Imaging Project earlier this year. USGS image by L. DeSmither.

This view of the eruption site within Kīlauea caldera was captured in the afternoon of Tuesday, September 12 from the southeast rim of Kaluapele. Multiple vents are spattering and effusing lava as the Kīlauea summit eruption nears the end of its second full day. USGS photo by M. Zoeller.
