This week, USGS Volcano Science Center scientists from other locations are helping the Hawaiian Volcano Observatory to deploy the 1,800 seismic nodes (small earthquake-detecting devices) across Kīlauea summit region.

This view of Halema‘uma‘u was captured from partway up the northwestern wall of the crater by an HVO geologist visiting the area on Wednesday, May 3, to collect geologic samples.

HVO scientists conducted a routine Kīlauea summit monitoring overflight during the morning of May 3, 2023. During the overflight, the helicopter flies around Halema‘uma‘u several times, and scientists take both regular pictures and infrared images that tell us about the temperatures on the crater floor. These images are used to create maps of the crater.

During a morning overflight on May 3, 2023, HVO scientists did not observe any activity within Halema‘uma‘u crater at the summit of Kīlauea. The most recent eruptive activity was observed on March 7.

A helicopter overflight on May 3, 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.

A pallet of buckets containing equipment for the Kīlauea Seismic Imaging Project is placed on netting so that it can be moved via helicopter sling load. These pallets package a small portion of the 1,800 seismic nodes (small earthquake-detecting devices) that are being deployed in Kīlauea summit region as part of the project.

The gear for the Kīlauea Seismic Imaging Project is staged and ready to be moved on Crater Rim Drive in the closed area of Hawai‘i Volcanoes National Park. Portions of Crater Rim Drive collapsed into Kīlauea caldera in 2018 and this project is partially funded by the Additional Supplemental Appropriations for Disaster Relief Act of 2019 (H.R.

An HVO scientist prepares netting to move a pallet of equipment via helicopter for the Kīlauea Seismic Imaging Project on April 28, 2023. During the project, caches of equipment are deployed around Kīlauea summit. HVO scientists and collaborators then distribute the equipment from the cache into a network across the summit region.

Scientists at the Hawaiian Volcano Observatory deployed caches of seismic node instruments via helicopter around Kīlauea summit yesterday, April 17. Seismic nodes are small earthquake-detecting devices and 1,800 of them are being placed across Kīlauea summit for the next two months as part of the Kīlauea Seismic Imaging Project.

Seismic nodes are prepared to be deployed to Kīlauea summit on April 17 as part of the Kīlauea Seismic Imaging Project. The nodes will be temporarily placed on the surface of Kīlauea's summit region for the next two months and will collect data that will outline the geometry and nature of the magma system beneath Kīlauea summit.

The lava lake basin that formed during the September 2021-December 2022 eruption was steaming the morning of April 14, 2023. This lava lake formed in the western half of Halema‘uma‘u crater and is part of a tapestry of deposits that have formed during different Kīlauea summit eruptions over the past several years.
