Map of Island of Hawaiʻi, highlighting the four active or potentially active volcanoes of the Island, the number of people living on each volcano based on 2020 census data, major roads (transportation corridors) and minor roads (proxy for population density), when each volcano last erupted, and each volcano’s national threat assessment designation.

This reference map depicts recent unrest along Kīlauea's upper East Rift Zone. Earthquakes that occurred between July 22–25, 2024, are shown as yellow circles. Recent ground deformation in this region, over the timeframe of July 15-24, 2024, is shown as colored fringes; data were recorded by the Italian Space Agency's (ASI) Cosmo-SkyMED satellite.

On July 25, USGS-Hawaiian Volcano Observatory (HVO) staff again drove down the closed portion of Chain of Craters Road in Hawaiʻi Volcanoes National Park to check for any damage related to the July 22-25 intrusion on Kīlauea's upper East Rift Zone. They found many new small cracks in Chain of Craters Road, including this one, near Hiʻiaka Crater.

This map shows recent deformation at Kīlauea, over the timeframe of July 15-24, 2024. Data were recorded by the Italian Space Agency's (ASI) 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.

On July 23, USGS-Hawaiian Volcano Observatory (HVO) staff drove down the closed portion of Chain of Craters Road in Hawaiʻi Volcanoes National Park to check for any damage related to the July 22-25 intrusion on Kīlauea's upper East Rift Zone.

This map shows recent deformation at Kīlauea, over the timeframe of June 6 to July 8, 2024. Data was recorded by the Italian Space Agency's (ASI) 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.

While HVO geologists were moving temporary webcams, they revisited the site of the June 3 eruption. This photo looks downrift, with the June 3 pad of lava in the upper right. Extensive cracking uprift of the fissure had weak residual outgassing and vibrant sulfur deposits. USGS photo by M. Patrick.

HVO geologists visited Kīlauea's Southwest Rift Zone and site of the June 3 eruption. The mission was to remove the temporary webcams deployed during that eruption, given a new temporary webcam nearby on Cone Peak. This photo shows the temporary webcam removed today near the June 3 eruption site. USGS photo by M. Patrick.

Sulfur deposits downwind of the cracks show the southwest direction of trade winds in Hawaii. These cracks were just uprift of the June 3 eruption site on Kīlauea. USGS photo by M. Patrick.

Once the sand was removed from the borehole, HVO field engineers could begin the process of leveling the UWE tiltmeter located at the base.

Before the UWE tiltmeter could be leveled, sand had to removed from the six-meter-deep (20 feet) borehole housing the tiltmeter. HVO field engineers use a high-power vacuum to remove the sand, in order to access the tiltmeter. USGS image by M. Warren.
