This reference map depicts the approximate location of fissure vents that began erupting from Kīlauea Southwest Rift Zone at approximately 12:30 a.m. HST on June 3, 2024. The most recent eruption in this region was during December 1974, which lasted only about 6 hours. At this time, it is not possible to say how long the eruption will last. 

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. USGS image by N.

The recent Southwest Rift Zone eruption of Kīlauea produced small volumes of lava and spatter. When very fluid lava lands on the ground, it may flatten upon impact and produce spatter known as 'pancake bombs.' When lava is stretched even further when cooling, thin strands of glass (Pele's hair) are created.

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.

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.

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.

GPS campaign equipment being staged prior to deployment on Mauna Loa for the annual survey. Temporary GPS receivers and antennas are placed on tripods centered over benchmarks, which serve as a reference point for centering of the antenna. The equipment is left in place to collect data for a couple of days at each site.

HVO staff are conducting the annual Mauna Loa GPS campaign. During the survey, GPS instruments are deployed at established benchmarks so that their recorded positions can be compared with those from previous years to discern subtle patterns of ground deformation associated with volcanic activity.

On May 10, HVO staff performed maintenance on the F1cam, the thermal camera at the summit of Kīlauea.

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.

Gravity measurements detect subsurface mass change—for example, magma accumulation or removal beneath the surface. In this way, gravity is a way of detecting changes in the magma reservoir that might otherwise be hidden. This photo shows two gravimeters used one-at-a-time to take measurements. USGS photo by A. Ellis.

On May 8, 2024, HVO staff conducted a gravity survey around Kaluapele (the summit caldera of Kīlauea) in response to current unrest and to supplement a larger survey done in March 2024. Measurements of gravity over time can show how mass is distributed beneath a volcano.

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.
