USGS Hawaiian Volcano Observatory geologists visited the young lava flows formed within the past 9 hours on the upper Southwest Rift Zone of Kīlauea volcano. At the eruption site, geologists documented lava flow margins, collected samples, and deployed a new webcam to monitor the eruption. USGS image taken the morning of June 3, 2024.

Lava fountains from the June 3, 2024 fissure eruption in Kīlauea's Southwest Rift Zone were estimated to have reached as high as 20 meters (66 feet), with an average height of 10 meters (33 feet). 

Scientists observed cracks in previous eruptive surfaces near the new fissure eruption southwest of Kīlauea's summit on June 3, 2024. These cracks ranged from a few centimeters (inches) to approximately 2 meters (6.6 feet) wide.

Frothy, glassy fragments of lava from the fountains of Kīlauea's June 3 eruption fissures were found scattered around newly-erupted lava flows. These tephra contain valuable geochemical information about the magma which fueled the eruption. USGS image by D. Downs. 

A new eruption began along Kīlauea's Southwest Rift Zone on June 3, 2024, and this map depicts activity on the eruption's first day. New lava flows are shown in red, only covering about 88 acres (36 hectares) of ground within relatively short distances of the eruptive fissures.

In this photo taken at about 6 a.m. HST on June 3, both lava fountains (left) and emissions of volcanic ash (right) are visible erupting from the new fissures in Kīlauea's Southwest Rift Zone. The ash is dark gray, while the remainder of the whitish plumes are composed of steam and other volcanic gases. USGS photo by Tricia Nadeau (HVO)

Around 6 a.m. HST on June 3, 2024, a helicopter overflight by USGS HVO scientists was observed by a field crew taking gas measurements of the new fissure eruption in Kīlauea's Southwest Rift Zone.  USGS photo by Tricia Nadeau (HVO)

A field team of HVO geochemists visited the site of Kīlauea's Southwest Rift Zone fissure eruption to measure gases released from the fissures. The team used a Fourier transform infrared (FTIR) spectrometer, an instrument that detects gas compositions on the basis of absorbed infrared light. USGS photo by Tricia Nadeau (HVO)

Early morning glow of the eruption southwest of Kīlauea summit on June 3, 2024. This image was taken at 4:27 a.m. HST looking southeast toward the eruptive fissures. USGS image by H Winslow.

On June 3, 2024, HVO field crews collected cooled spatter from the then inactive vents of Kīlauea's Southwest Rift Zone eruption. Samples are processed in the laboratory to determine their chemistry, which helps HVO scientists understand where the magmas were stored prior to eruption. USGS photo by K. Lynn.

The recent Southwest Rift Zone eruption of Kīlauea produced small volumes of lava, and fountains left volcanic spatter on top of and beyond the extent of the newly erupted flows. The collected pieces of spatter range in size up to 4 inches (1 to 10 centimeters). USGS image by A.R. Nalesnik.

A close up of the cone that formed in the June 2023 eruption, at the southwest end of Halema‘uma‘u crater, at the summit of Kīlauea. Lava from the vent poured into a ponded region, which later drained as the eruption waned. USGS photo by M. Patrick.

An HVO scientist takes gravity measurements at a benchmark near a crater in Hawaiʻi Volcanoes National Park. The gravimeter is the small, shoebox-sized instrument, which can measure a change in the force of gravity to one-in-one billionth of the force you feel every day. USGS photo by A. Ellis.

This map shows recent deformation at Kīlauea from April 19 to May 5, 2024, as recorded by the Italian Space Agency's (AGI) Cosmo-SkyMED satellite. Colored fringes denote areas of ground deformation, with more fringes indicating more deformation.  Each color cycle represents 1.5 cm (0.6 in) of ground motion indicative of inflation as the magma reservoi

This map depicts recent unrest at Kīlauea. Yellow circles mark the locations of approximately 1,600 earthquakes that have occurred between April 27 and May 2, 2024. Most earthquakes have been smaller than magnitude-2, with locations clustering in an area known as the upper East Rift Zone or East Rift connector.

This photo shows the southwest portion of Kaluapele (Kīlauea's summit caldera). In the lower right corner of the image is the cone formed during the June 2023 eruption. This cone hosted impressive lava fountaining that supplied lava through a narrow channel into the lava pond in the lower left portion of the image. USGS photo by M. Patrick.

Despite a significant increase in small earthquakes at the summit and upper East Rift Zone in recent days, activity at the surface was quiet On May 1, 2024. This photo shows the floor of Halema‘uma‘u, at the summit of Kīlauea, which last erupted in September 2023.

The V1cam webcam, which provides the livestream at the summit of Kīlauea, is a pan-tilt-zoom model that allows HVO staff to adjust the view remotely based on changes in activity in the caldera. USGS photo by M. Patrick.
