An eruption at the summit of Kīlauea volcano began on September 10, 2023. The main fountain, which HVO geologists estimate is approximately 50 meters tall, is on the eastern margin of Halemaʻumaʻu crater. As of approximately 4:30 p.m.

Map of the American Samoa volcano-monitoring network (top). Data from Wake Island hydrograph (located about 4,500 km, or 2,900 miles, northwest of Taʻū Island) shows the general trend in the number of events during the 2022 earthquake swarm (bottom left). Locations for larger earthquakes (M2.5 and greater) are available starting August 20, 2022 (bottom right).

A summit eruption of Kīlauea volcano, within Halemaʻumaʻu crater, began at approximately 4:44 a.m. on June 7, 2023. Lava is flowing on the crater floor and there are several active vent sources. The eruption at Kīlauea’s summit is occurring within a closed area of Hawai'i Volcanoes National Park and high levels of volcanic gas are the primary hazard of concern.

During the annual Mauna Loa 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.

The Vibroseis vehicle has been operating on roads in Hawai‘i Volcanoes National Park and in the Kīlauea summit region for the past several weeks. The vehicle belongs to the Natural Hazards Engineering Research Infrastructure (NHERI) experimental facility at the University of Texas at Austin, which is supported with funding from the National Science Foundation.

A helicopter overflight on May 23, 2023, allowed for aerial visual and thermal imagery to be collected of Halema‘uma‘u crater at the summit of Kīlauea. No active lava was present in the crater, with only scattered warm spots on the crater floor.

Hawaiian Volcano Observatory geophysicists are performing the annual GPS survey of Mauna Loa. Most Mauna Loa GPS campaign survey sites have been occupied every year since 1996, whereas less active volcanoes Hualālai and Haleakalā are surveyed every 3–5 years. USGS image by A. Ellis.

USGS scientists deploy a bucket, containing a seismic node, which was set on a hard lava flow surface. There are now about 1,800 seismic nodes deployed around the Kīlauea summit region to record seismic signals for the next three weeks.
