In this photo, taken on October 3, 2023, near Kīlauea's coastline in Hawai‘i Volcanoes National Park, a GPS antenna is mounted on a fixed rod. A GPS receiver, housed in the yellow box, records the positions that can be compared with those from previous years to discern subtle patterns of ground deformation associated with volcanic activity.

During the annual Kīlauea GPS campaign, scientists temporarily deploy a number of GPS instruments at established benchmarks; their recorded positions can be compared with those from previous years to discern subtle patterns of ground deformation associated with volcanic activity.

Hawaiian Volcano Observatory geophysicists completed the annual GPS survey of Kīlauea. Most Kīlauea and Mauna Loa GPS campaign survey sites have been occupied every year since the early 1990s, whereas the less active volcanoes Hualālai and Haleakalā are surveyed every 3–5 years.

This reference map depicts the Kīlauea summit region following the most recent eruption in September 2023. The provided statistics for the eruption were measured and calculated from detailed aerial mapping that was completed after activity had ceased; a much weaker gas plume allowed for more accurate modeling of the post-eruption lava surface.

This map shows recent unrest at Kīlauea summit. Yellow circles denote earthquake locations from October 4–24, 2023, as recorded by HVO seismometers. Nearly 2,000 earthquakes were detected during this time period. Colored fringes denote areas of ground deformation from September 24–October 10 as measured by satellite radar.

A GPS site is occupied on the south flank of Kīlauea, inside Hawai‘i Volcanoes National Park, as part of the 2023 annual campaign survey. The survey data will supplement continuous data collected at permanent GPS sites on Kīlauea volcano. The Pacific Ocean is visible in the background. USGS photo by A. Ellis.

A GPS survey benchmark is being occupied on the Southwest Rift Zone of Kīlauea. The metal disk on the ground beneath the tripod is the benchmark, which is cemented to the lava flow surface. Each year during the Kīlauea GPS campaign survey, a high-precision GPS unit is centered over the benchmark to collect data.

HVO field crews observed no eruptive activity at the summit of Kīlauea this morning, September 17, 2023. The eruption within the caldera that began on September 10 stopped on September 16. Some areas of steam persist, and overnight webcam views showed incandescence across the eruption area as lava erupted over the past week continues to cool. USGS photo by J.
